“…The developed hysteresis model of the nail connections is implemented into ABAQUS/Explicit as a user-defined element via the Subroutine VUEL. The behaviour of the nail connections is treated as isotropic, since the orthotropic behaviour has been proved negligible [26,27]. In the user-defined element, the oriented spring pair [21] was adopted to represent the behaviour of the nail connections in any given direction.…”

“…However, most of these models were developed within specific software packages. To model the behavior of wood shear walls in a more versatile way, Xu and Dolan [16] modified the Bouc-Wen-Barer-Wen hysteresis model to represent wood shear walls and embedded the model in a commercially available software package ABAQUS through a user-defined element. An oriented spring pair model was also implemented in ABAQUS by Judd and Fonseca [17] to model nail connections in wood diaphragms and shear walls.…”

The lateral performance of timber-steel hybrid shear wall systems with regard to the interaction between the steel frame and the infill wood shear wall was investigated in this paper. A numerical model for the timber-steel hybrid shear wall system was developed and verified against test results. Design parameters, such as the lateral infill-to-frame stiffness ratio and the arrangements of wood-steel bolted connections were studied using the numerical model. Some design recommendations were also proposed based on the parametric analysis. In the hybrid shear wall system, the infill wood wall was found to resist a major part of the lateral load within relatively small wall drifts, and then the steel frame provided more lateral resistance. Under seismic loads, the infill wood wall could significantly reduce the inter-story drift of the hybrid system, and a complementary effect between the infill wood wall and the steel frame was observed through different lateral load resisting mechanisms, which provided robustness to the hybrid shear wall systems.

“…However, instead of relying on the assumptions of von-Mises yield and linear kinematic hardening, the constitutive formulation proposed herein accounts for any type of yield function and kinematic hardening, within the framework of classical rateindependent plasticity. The advantages of a Bouc-Wen type model accounting for deformation dependent hardening were recently highlighted in [47,60] where the linear kinematic hardening coefficient of the Bouc-Wen model is substituted by a continuous function derived from calibration of experimental data.…”

A hysteretic multiscale formulation for nonlinear dynamic analysis of composite materials

A new multiscale finite element formulation is presented for nonlinear dynamic analysis of heterogeneous structures. The proposed multiscale approach utilizes the hysteretic finite element method to model the microstructure. Using the proposed computational scheme, the micro-basis functions, that are used to map the microdisplacement components to the coarse mesh, are only evaluated once and remain constant throughout the analysis procedure. This is accomplished by treating inelasticity at the micro-elemental level through properly defined hysteretic evolution equations. Two types of imposed boundary conditions are considered for the derivation of the multiscale basis functions, namely the linear and periodic boundary conditions. The validity of the proposed formulation as well as its computational efficiency are verified through illustrative numerical experiments.
