Analysis of wood-composite laminated frames under dynamic loads—analytical models and model validation. Part Ⅱ: frame model

摘要

This paper describes the analytical models that were used to simulate the full time-history response of timber frames subjected to dynamic loads. Three-dimensional models of two-story timber frames were developed and verified via small- and full-scale shake table experiments. The modeling of the hysteretic properties of the connections was presented in Part Ⅰ. Verification of the frame model was done using the time-history response and the dissipated energy as a measure of accuracy. The comparison reveals that the presented approach can be successfully used to simulate the load-history-dependent behavior of inelastic systems. The developed model reliably predicted the frame response in the nonlinear range and is capable of simulating initial slippage in the joints due to previous loading. The proposed model is applicable to design and analyze timber frames of arbitrary geometry and configuration under arbitrary loads.
