Повний текст джерелаCross Laminated Timber (CLT, or crosslam) panels are engineered timber products composed of layers made of wooden lamellas placed side by side, glued on their upperand lower faces and stacked crosswise. In the present thesis, the influence of lateral spaces between lamellas of each layer on the panel’s mechanical response is investigated with modeling and tests. Both configurations of standard panels having short spaces and innovative CLT panels with large spaces are analyzed.As a first approach, the bending behavior of standard crosslam was modeled by means of an equivalent-layer model based on simplified hypotheses on mechanical properties of laterally glued or unglued layers. The good agreement of the predicted behavior with an experiment of the literature finally allowed an investigation on several CLT properties by means of parameter studies.Then, 4-points bending tests on standard and innovative CLT floors were performed in order to quantify the influence of periodic spaces on the panels' mechanical response. It appears that the influence of transverse shear effects on the elastic and failure behavior of spaced CLT increases with the increasing spaces between boards.In order to take into account transverse shear effects, spaced CLT have been modeled as periodic thick plates by means of a higher-order plate theory for laminated plates. This model has been applied to the geometry of spaced CLT with a periodic homogenization scheme. Existing simplified methods for spaced crosslam were compared as well with refined modeling and test results. Moreover, available in-plane shear tests of the literature have been compared to the modeling results. It appears that the bending behavior of spaced CLT can be predicted with simplified existing approaches, while only the more refined modeling can predict the in-plane and transverse shear behavior. Then, closed-form solutions for predicting spaced CLT elastic behavior were derived in order to encourage the application of spaced CLT panels in modern timber construction.One further study within this thesis concerns the analysis of fire-exposed standard CLT floors. The comparison between test results and both advanced and simplified modeling led to a suggestion for a possible improvement the standard fire design model

Повний текст джерелаMultilayered timber structures, assembled using densified wood dowels, represent a sustainable and innovative solution for the construction sector. The development of predictive finite element models requires a solid representation of the geometry for modelling the complex mechanical behaviour of these structures. However, solid models are costly, especially in the context of variability studies and optimization. In this thesis, solid, solid-shell, and solid-beam approaches are developed to obtain accurate models that can be considered as the best compromise. The study of the mechanical behaviour of multilayered timber structures reveals that the layers adopt a shell-like behaviour, while the dowels behave like beams. Higher-order displacement fields through the thickness of the layers and through the cross-section of the dowels are identified. To meet these displacement fields while maintaining a solid representation, two methods have been developed. A first method exploits standard solid elements by applying shell theories through the thickness of the layers and beam theories through the sections of the dowels. A second method uses a 32-node hexahedral element and is inspired by the principle of solid-shell and solid-beam elements, with a single element through the thickness of the layers and a single element through the section of the dowels. The results demonstrate that the methods proposed in this thesis lead to effective modelling tools for multilayered timber structures assembled with densified wood dowels. These methods offer perspectives for future developments and applications to other types of structures

Повний текст джерелаThe thesis investigates new layered fibreboard products with enhanced properties whilst minimizing their environmental impact. A review of literature revealed that layering technique, understood in term of producing multi-layered mattresses before pressing, brings many benefits in case of several types of wood-based panels, notably OSB and particleboard. Three main concepts to change layers through the fibreboard thickness were considered in the current study: effect of fibre size; effect of fibre origin and fibre pre-treatment with the enzymes. The smallest fibres were found to improve board performances when placed in outer layers, while the largest fibres are applied in the core. Fibre fractionation was suggested as an efficient way to separate the fibres by size and reduce energy consumption during their production. Paper rejects were investigated as an alternative fibre source. The substitution level could vary as 10 – 50 % and depends on final requirements to the boards. Fibre pre-treatment with enzymes was suggested for the top layer of the boards to increase it hydrophobicity and maintain mechanical resistance due to the bottom layer composed of untreated fibre. The multi-layer structure was analysed theoretically and a structural model was developed to predict MOR of the boards as a function of raw material properties. The final products showed 7 % of energy efficiency increase, 16 % reduced carbon footprint and up to 20 % raw material saving

Повний текст джерелаThis research deals with the development of a pre-existing equivalent model by including the modeling of imperfect interfaces. The aim is to improve the accuracy of the modeling in current equivalent models, which generally assume perfect continuity of the stress and displacement fields. The coupling conditions at the interfaces of the multilayer equivalent model are therefore modified. They are modeled using a complex stiffness. A high stiffness corresponds to good coupling; conversely, a low stiffness corresponds to poor coupling. This is described by a single parameter, the interface parameter, which is the inverse of the interface stiffness. This parameter is dependent on each layer, but can also be used as a global value for the apparent imperfection of the entire structure. The methodology for characterizing a planar structure, and in particular a beam, is detailed in the third chapter of this thesis manuscript. The main post-processing elements employed are presented in detail, and have enabled the characterization method to be extended up to 100 kHz. Finally, modeling and experimental methodology are employed in a complementary manner. The aim is to characterize the dynamics of samples with imperfect interfaces. The effect of imperfect interfaces is visualized not only as a function of frequency, but also as a function of space. A complementary approach between these two visualizations is finally carried out to provide more detailed characterization results

Повний текст джерелаThe development of modern technologies requires that one use materials presenting high mechanical properties specific to their employment,but whose densities are low. The composite materials are materials which fulfil the preceding requirements. Because of their interest, the composite materials were initially used in aerospace, automotive, and construction industries. In composites, a class of particular interest ragarding the possibilities of design and development concern the sandwich structures resulting from a general assembly of a skin material with high stiffness and core materials of low density. The final properties of the materials are directly derived to the industry, many developments and studies in recent years have been aimed at optimizing the ratio mechanical performance over density. This thesis was undertaken with the same objective, but by having a strategy of optimization being focused more particulary on core materials. Our process is to reconsider in its entirety core materials and to propose a new concept of core complex which rests on the material stacking of different nature according to a quite precise sequence. The experimental results are correlated with those obtained by a theoretical approach based on a finite element method
