“…Achieving accurate results in a nonlinear time‐history analysis requires accurate hysteretic connection models since the joints are responsible for most of the damping of inelastic systems3. Many hysteresis models have been proposed to describe the load‐history‐dependent behavior of timber joints subjected to reversed cyclic loading4, 5. Well known is the DRAIN 2DX program from Powel6 for the dynamic analysis of nonlinear structures.…”

This paper describes the analytical models of timber connections that were used to simulate the full time‐history response of moment‐resisting frames subjected to dynamic loads. Special attention was paid to connection modeling to capture the hysteretic damping that significantly affected the performance of the system subjected to dynamic forces. To model the hysteretic properties of the dowel‐type connections a combination of bilinear springs and gaps was used. This approach allows the modeling of various hysteretic shapes including pinching, asymmetric behavior, contact phenomena, and an initial slip of the fasteners. Load–deformation curves obtained from the cyclic experiments of small‐ and full‐scale joints were used to extract the model parameters. The hysteretic models were verified by comparing the simulation with the experimental data obtained from cyclic tests. The comparison reveals that the presented approach can be successfully used to simulate the load‐history‐dependent behavior of timber joints, provided that strength degradation is negligible and a brittle failure does not occur. The predictive ability of a 3D frame model will be demonstrated in Part II by comparing the simulation with the results of shake table experiments.

“…As such, the possibility of creating and solving multiple simulations using FEM integrated with the design of experiments provides a huge advantage for efficient design optimization pathways [29,31]. Hence, research efforts have been directed toward the application of FEM for the analysis of numerous properties of wood and wood-based composite that include stress distribution [20,32], seismic performance [33], wood torrefaction [34], wood drying [35,36], microwave scattering [37], corner joint strength [28,38], nonlinear multiphase modeling for inhomogeneous composite material [39], the influence of orientation and intra-ring variation on wood strands [40], fracture behavior [41,42], viscoelastic-induced crack propagation [43], size effect on mechanical properties [44,45], etc. Therefore, this review aims to provide a contextual outlook on different scenarios of FEM applications in studying the performance characteristics of wood and solid wood-based composites as well as reconstituted wood and other lignocellulosic-based composites.…”

Performance evaluations of wood and other lignocellulosic-based composites involve complex scenarios of several factors such as material heterogeneity and geometry that often leads to complicated, expensive, and time-consuming experimental procedures. Hence, the application of computational modeling and simulation is desirable to mitigate these biocomposites’ performance testing challenges. This review paper, therefore, presents an outlook on the finite element method (FEM) application in probing performance characteristics of wood and solid wood-based composites as well as reconstituted wood and other lignocellulosic-based composites. Notwithstanding the complex nature of wood and other lignocellulosic biomass, the feasibility of FEM application in characterizing their performances has been favorably demonstrated. Going forward, broader applications of FEM combined with the design of experiments would further establish developing protocols. More exploration of FEM-based parametric and optimization studies would facilitate comprehensive, cost-efficient, and swift biocomposites design and performance optimization processes thereby enhancing their acceptance and implementation in target applications.

“…Thus, in order to improve the lateral resistance of the post-and-beam structure, modern wall technologies are used in complement. Two technologies are considered: light-frame shear walls, which provide a reference of lateral-resistant wall with well-known performance [9][10][11], and Structural Insulation Panels (SIP) [1], which provide at the same time a lateral resistance and an increased thermal insulation. Moreover, the traditional woodwood connections of the post-and-beam structure are replaced with joints with metallic connectors in order to increase the ductility and energy dissipation of the structure, thereby providing a better safety through a less sudden and more visually noticeable failure.…”

This paper presents experimental and numerical tests on a recently developed timber column concealed base joint. This joint was designed to replace the wood-wood connection found in the post-and-beam structure of Hanok, the traditional Korean timber house. The use of metallic connectors provides an increased ductility and energy dissipation for a better performance under reversed loading, especially seismic. In this study, we investigate the performance of the joint under pseudo-static reversed cyclic moment loading through the study of its ductility and energy dissipation. We first perform experimental tests. Results show that the failure occurs in the metallic connector itself because of stress concentrations, while no brittle fracture of wood occur. Subsequent numerical simulations using a refined finite element model confirm these conclusions. Then, using a practical modification of the joint configuration with limited visual impact, we improve the ductility and energy dissipation of the joint while retaining a same level of rotational strength as the originally designed configuration. We conclude that the joint has a satisfying behavior under reversed moment loading for use in earthquake resistant timber structure in low to moderate seismicity areas like Korea.
