description Publicationkeyboard_double_arrow_right Article 2021 FrancePublisher:Elsevier BV Authors: ASLI, M.; BRACHELET, F.; SASSINE, E.; ANTCZAK, Emmanuel;ASLI, M.; BRACHELET, F.; SASSINE, E.; ANTCZAK, Emmanuel;Abstract Most building materials, and more particularly bio-based materials, are subject to hygrothermal transfers in the environment in which they are disposed. These transfers depend on their thermophysical characteristics as well as the ambient humidity and temperature conditions. In such environment, and despite these variations, the material must be able to ensure in a sustainable manner, the functions for which it was implemented (thermal, mechanical, acoustic …). Among these materials, hemp concrete, which is a bio-based material, is widely considered in building construction for its superior thermal and hygroscopic performance. The hygrothermal modelling of such materials in real conditions is essential for a better understanding of buildings’ energy performances. Several works targeted the numerical hygrothermal modelling of hemp concrete; however most of them are done in controlled laboratory conditions, which may be different from the real buildings scenarios. In this paper, heat and mass transfer are investigated both numerically and experimentally in real conditions. The hygrothermal properties of hemp concrete were first determined through laboratory experiments; then, an experimental wall segment made of hemp concrete was instrumented in real ambient conditions in order to validate the Philip and De Vries model describing heat and mass transfer. The comparison of the numerical results to the experimental data leads to interesting results regarding local temperature and relative humidity variations. Moreover, numerical investigation of the moisture buffer values of hemp concrete was performed and the results were validated by bibliographic data. The hemp concrete was found to be a very interesting potential hygrothermal regulation material in terms of thermal conductivity , decrement factor, time lag, and humidity regulation.

The fiber beam element approach has been proved to be an interesting modeling strategy, but needs to be improved for shear effects. This can be achieved by enhancing the cross-section kinematics with a warping displacement field. This field must be free from the cross-section rigid body motions, for the problem to be well posed. This condition can be enforced by projecting the warping displacements orthogonally to the space of the plane cross-section displacements. The present contribution proposes a kinematic enhancement for a Timoshenko fiber beam element with a new formulation of the projection functions. The warping shape of the cross-section is computed along with the beam displacements and rotations by an implicit solution procedure. The proposed formulation takes into account the possible material heterogeneity of the cross-section. It enables the warping profile to evolve in time with the material damage state, as may occur in reinforced concrete structures. The element formulation is validated using an analytical solution in the case of transverse shear, and 3D simulations of beams subject to shear and torsion. To address nonlinear behavior, a comparison to experimental results is performed. The first case study shows that including warping in the model drastically improves the prediction of the experimental behavior of concrete beams in torsion. The second case study shows the ability of the model to deal with cyclic bending of a reinforced concrete column.

A VI-ABH is an adaptation of the classical ABH design consisting of a beam with a tapered edge of decreasing thickness creating an acoustic black hole (ABH), complemented by contact points on which the beam impacts during its vibration. The contact nonlinearity creates a rapid and efficient transfer of vibrational energy from the low-frequency range, where the ABH is known to be ineffective, to the high-frequency range, thus improving the global passive vibration mitigation characteristics. The optimal design of a VI-ABH follows the rule of locating the contact points at local maxima of the low-frequency modes. Experiments clearly demonstrate the gain in performance, both in forced and free vibrations.

Abstract In real structures, the proportional damping assumption is never strictly verified. Indexes of non-proportionality are then necessary to determine if this assumption leading to real modes still remains valid. If not, complex modes will appear and moreover, if their corresponding natural frequencies are close, their imaginary part can become large. In this paper, a new non-proportionality index, quantifying the “complexity” of mode shapes, is presented, derived from the notion of optimal complex modes introduced by Adhikari. This new index is designed for experimental results, for which the system’s parameters are not known, and proven to be equal to the previous one up to the first order on damping. Modal identification based on wavelet analysis is considered promising in this study for processing free responses of non-proportionally damped systems, integrated in noise, to directly obtain complex modes. A procedure for choosing an appropriate quality factor for the time-frequency resolution, necessary to get correct identification results in the case of free responses combined with responses to ambient excitation and/or to additive noise, is detailed. The proposed identification technique based on Continuous Wavelet Transform (CWT) is finally applied on different transient responses of a masonry wall specimen during an experimental campaign comprising simultaneous vibrations and shear-compression tests. The results of the CWT method for modal identification are compared with those obtained by a classical modal analysis technique, called Least Squares Complex Frequency method, by means of the Modal Assurance Criterion and the proposed non-proportionality index.

It proposes three different novel algorithms by exploiting the inherent Toeplitz /Sylvester structures impeded in the system model. The first algorithm is the structured signal subspace (SSS) method, which involves direct estimation of the signal from a multiple-input multiple-output (MIMO) system. The second algorithm is the structured channel subspace (SCS) method, whereby the MIMO channel matrix is estimated by employing its embedded Toeplitz structure. The last algorithm deals with the bilinear blind identification by utilizing the information (embedded structure) of both row and column subspaces of the received signals. The proposed methods exploit the block Sylvester structure of the signal and the channel matrix to formulate a quadratic cost function whose minimization enables us to estimate the desired system parameters. The simulation results of the proposed structured subspace methods are appealing in different scenarios.

The procedure allows to define a nonlinear mapping in order to derive accurate reduced-order models (ROM) relying on invariant manifold theory. The proposed reduction strategy is direct and simulation free, in the sense that it allows to pass from physical coordinates (FE nodes) to normal coordinates, describing the dynamics in an invariant-based span of the phase space. The number of master modes for the ROM is not a priori limited since a complete change of coordinate is proposed. The underlying theory ensures the quality of the predictions thanks to the invariance property of the reduced subspace, together with their curvatures in phase space that accounts for the nonresonant nonlinear couplings. The method is applied to a beam discretised with 3D elements and shows its ability in recovering internal resonance at high energy. Then a fan blade model is investigated and the correct prediction given by the ROMs are assessed and discussed. A method is proposed to approximate an aggregate value for the damping, that takes into account the damping coefficients of all the slave modes, and also using the Rayleigh damping model as input. Frequency-response curves for the beam and the blades are then exhibited, showing the accuracy of the proposed method. Comment: 34 pages, 10 figures, 2 tables, submitted to CMAME

The extensive literature on this NP-hard problem mostly focuses on heuristics. Using an arc-flow based optimization approach, we construct a novel formulation that represents it as a problem of determining flows in graphs. The size of the formulation increases with the machine capacity and with the number of distinct sizes and processing times among the jobs, but it does not increase with the number of jobs, which makes it very effective to solve large instances to optimality, especially when multiple jobs have equal size and processing time. We compare our model to other models from the literature, showing its clear superiority on benchmark instances and proving optimality of random instances with up to 100 million jobs.

In the Gaussian (or second-order) case this property is typically related to the periodic autocovariance function. Thus, many classical methods for detection of cyclostationarity are based on the analysis of autocovariance in time and frequency domain. In the frequency analysis, one of the most powerful tool is the spectral coherence. However, many real signals exhibit behavior adequate to non-Gaussian behavior. This is mostly related to the impulsiveness of the signals. In that case, the usage of the heavy-tailed distribution is a more appropriate. We propose to consider α -stable distribution which seems to be perfect for the impulsive behavior modeling. In this paper, the α -stable cyclostationary signals are examined and the generalization of the classical spectral coherence is proposed. The new bi-frequency map is based on the autocovariation function, which is defined for α -stable signals. It is demonstrated that the proposed statistic is not influenced by the large observations contained in the signal and thus it is more appropriate for the considered case. The introduced approach is validated for the simulated signal and for the real vibration signal from the rolling element bearings operating in crushing machine.

As the demand for thermal comfort in buildings continues to grow, energy consumption increases accordingly. The application of phase change materials (PCM) to building envelopes can improve thermal energy storage, thus they can be used to increase the thermal mass of buildings. This article shows the efficiency of using PCMs to mitigate building cooling demands in eight cities representing the Mediterranean region: Al Hoceima (Morocco), Malaga (Spain), Marseille (France), Taher (Algeria), Naples (Italy), Tripoli (Libya), Ankara (Turkey), and Port Said (Egypt). The energy performance of three types of building: single-family, collective housing and hotel housing, built with hollow bricks, with and without PCMs, is evaluated in these cities using a numerical model based on the apparent heat capacity. A wide range of PCM melting temperatures is studied (from 22 °C to 32 °C). The results confirm that climate profoundly influences the storage/release process of PCMs. Regardless of the building typology, energy savings can reach 56% in the North-East Mediterranean cities using a PCM with a 26 °C melting temperature, while no energy savings have been noted for the South-East cities. Finally, a correlation between the energy savings and the Cooling Degree Day is demonstrated, resulting in the recommendation of a PCM with a 26 °C median melting temperature in a given location.

These transfers depend on their thermophysical characteristics as well as the ambient humidity and temperature conditions. In such environment, and despite these variations, the material must be able to ensure in a sustainable manner, the functions for which it was implemented (thermal, mechanical, acoustic …). Among these materials, hemp concrete, which is a bio-based material, is widely considered in building construction for its superior thermal and hygroscopic performance. The hygrothermal modelling of such materials in real conditions is essential for a better understanding of buildings’ energy performances. Several works targeted the numerical hygrothermal modelling of hemp concrete; however most of them are done in controlled laboratory conditions, which may be different from the real buildings scenarios. In this paper, heat and mass transfer are investigated both numerically and experimentally in real conditions. The hygrothermal properties of hemp concrete were first determined through laboratory experiments; then, an experimental wall segment made of hemp concrete was instrumented in real ambient conditions in order to validate the Philip and De Vries model describing heat and mass transfer. The comparison of the numerical results to the experimental data leads to interesting results regarding local temperature and relative humidity variations. Moreover, numerical investigation of the moisture buffer values of hemp concrete was performed and the results were validated by bibliographic data. The hemp concrete was found to be a very interesting potential hygrothermal regulation material in terms of thermal conductivity , decrement factor, time lag, and humidity regulation.

The fiber beam element approach has been proved to be an interesting modeling strategy, but needs to be improved for shear effects. This can be achieved by enhancing the cross-section kinematics with a warping displacement field. This field must be free from the cross-section rigid body motions, for the problem to be well posed. This condition can be enforced by projecting the warping displacements orthogonally to the space of the plane cross-section displacements. The present contribution proposes a kinematic enhancement for a Timoshenko fiber beam element with a new formulation of the projection functions. The warping shape of the cross-section is computed along with the beam displacements and rotations by an implicit solution procedure. The proposed formulation takes into account the possible material heterogeneity of the cross-section. It enables the warping profile to evolve in time with the material damage state, as may occur in reinforced concrete structures. The element formulation is validated using an analytical solution in the case of transverse shear, and 3D simulations of beams subject to shear and torsion. To address nonlinear behavior, a comparison to experimental results is performed. The first case study shows that including warping in the model drastically improves the prediction of the experimental behavior of concrete beams in torsion. The second case study shows the ability of the model to deal with cyclic bending of a reinforced concrete column.

A VI-ABH is an adaptation of the classical ABH design consisting of a beam with a tapered edge of decreasing thickness creating an acoustic black hole (ABH), complemented by contact points on which the beam impacts during its vibration. The contact nonlinearity creates a rapid and efficient transfer of vibrational energy from the low-frequency range, where the ABH is known to be ineffective, to the high-frequency range, thus improving the global passive vibration mitigation characteristics. The optimal design of a VI-ABH follows the rule of locating the contact points at local maxima of the low-frequency modes. Experiments clearly demonstrate the gain in performance, both in forced and free vibrations.

Abstract In real structures, the proportional damping assumption is never strictly verified. Indexes of non-proportionality are then necessary to determine if this assumption leading to real modes still remains valid. If not, complex modes will appear and moreover, if their corresponding natural frequencies are close, their imaginary part can become large. In this paper, a new non-proportionality index, quantifying the “complexity” of mode shapes, is presented, derived from the notion of optimal complex modes introduced by Adhikari. This new index is designed for experimental results, for which the system’s parameters are not known, and proven to be equal to the previous one up to the first order on damping. Modal identification based on wavelet analysis is considered promising in this study for processing free responses of non-proportionally damped systems, integrated in noise, to directly obtain complex modes. A procedure for choosing an appropriate quality factor for the time-frequency resolution, necessary to get correct identification results in the case of free responses combined with responses to ambient excitation and/or to additive noise, is detailed. The proposed identification technique based on Continuous Wavelet Transform (CWT) is finally applied on different transient responses of a masonry wall specimen during an experimental campaign comprising simultaneous vibrations and shear-compression tests. The results of the CWT method for modal identification are compared with those obtained by a classical modal analysis technique, called Least Squares Complex Frequency method, by means of the Modal Assurance Criterion and the proposed non-proportionality index.

It proposes three different novel algorithms by exploiting the inherent Toeplitz /Sylvester structures impeded in the system model. The first algorithm is the structured signal subspace (SSS) method, which involves direct estimation of the signal from a multiple-input multiple-output (MIMO) system. The second algorithm is the structured channel subspace (SCS) method, whereby the MIMO channel matrix is estimated by employing its embedded Toeplitz structure. The last algorithm deals with the bilinear blind identification by utilizing the information (embedded structure) of both row and column subspaces of the received signals. The proposed methods exploit the block Sylvester structure of the signal and the channel matrix to formulate a quadratic cost function whose minimization enables us to estimate the desired system parameters. The simulation results of the proposed structured subspace methods are appealing in different scenarios.

The procedure allows to define a nonlinear mapping in order to derive accurate reduced-order models (ROM) relying on invariant manifold theory. The proposed reduction strategy is direct and simulation free, in the sense that it allows to pass from physical coordinates (FE nodes) to normal coordinates, describing the dynamics in an invariant-based span of the phase space. The number of master modes for the ROM is not a priori limited since a complete change of coordinate is proposed. The underlying theory ensures the quality of the predictions thanks to the invariance property of the reduced subspace, together with their curvatures in phase space that accounts for the nonresonant nonlinear couplings. The method is applied to a beam discretised with 3D elements and shows its ability in recovering internal resonance at high energy. Then a fan blade model is investigated and the correct prediction given by the ROMs are assessed and discussed. A method is proposed to approximate an aggregate value for the damping, that takes into account the damping coefficients of all the slave modes, and also using the Rayleigh damping model as input. Frequency-response curves for the beam and the blades are then exhibited, showing the accuracy of the proposed method. Comment: 34 pages, 10 figures, 2 tables, submitted to CMAME

The extensive literature on this NP-hard problem mostly focuses on heuristics. Using an arc-flow based optimization approach, we construct a novel formulation that represents it as a problem of determining flows in graphs. The size of the formulation increases with the machine capacity and with the number of distinct sizes and processing times among the jobs, but it does not increase with the number of jobs, which makes it very effective to solve large instances to optimality, especially when multiple jobs have equal size and processing time. We compare our model to other models from the literature, showing its clear superiority on benchmark instances and proving optimality of random instances with up to 100 million jobs.

In the Gaussian (or second-order) case this property is typically related to the periodic autocovariance function. Thus, many classical methods for detection of cyclostationarity are based on the analysis of autocovariance in time and frequency domain. In the frequency analysis, one of the most powerful tool is the spectral coherence. However, many real signals exhibit behavior adequate to non-Gaussian behavior. This is mostly related to the impulsiveness of the signals. In that case, the usage of the heavy-tailed distribution is a more appropriate. We propose to consider α -stable distribution which seems to be perfect for the impulsive behavior modeling. In this paper, the α -stable cyclostationary signals are examined and the generalization of the classical spectral coherence is proposed. The new bi-frequency map is based on the autocovariation function, which is defined for α -stable signals. It is demonstrated that the proposed statistic is not influenced by the large observations contained in the signal and thus it is more appropriate for the considered case. The introduced approach is validated for the simulated signal and for the real vibration signal from the rolling element bearings operating in crushing machine.

As the demand for thermal comfort in buildings continues to grow, energy consumption increases accordingly. The application of phase change materials (PCM) to building envelopes can improve thermal energy storage, thus they can be used to increase the thermal mass of buildings. This article shows the efficiency of using PCMs to mitigate building cooling demands in eight cities representing the Mediterranean region: Al Hoceima (Morocco), Malaga (Spain), Marseille (France), Taher (Algeria), Naples (Italy), Tripoli (Libya), Ankara (Turkey), and Port Said (Egypt). The energy performance of three types of building: single-family, collective housing and hotel housing, built with hollow bricks, with and without PCMs, is evaluated in these cities using a numerical model based on the apparent heat capacity. A wide range of PCM melting temperatures is studied (from 22 °C to 32 °C). The results confirm that climate profoundly influences the storage/release process of PCMs. Regardless of the building typology, energy savings can reach 56% in the North-East Mediterranean cities using a PCM with a 26 °C melting temperature, while no energy savings have been noted for the South-East cities. Finally, a correlation between the energy savings and the Cooling Degree Day is demonstrated, resulting in the recommendation of a PCM with a 26 °C median melting temperature in a given location.
