ANALYTICAL SEISMIC RESPONSE OF WOOD SHEAR WALLS USING HYSTERESIS MODELS OF NAILED JOINTS

The nonlinear seismic response of wood shear walls was studied using s ix hysteresis models for nailed joints: bilinear, hybrid, Clough, Q-hy st, Origin-oriented, and Kivell models. The main objectives of the stu dy were to investigate the performance and predictions of these models and to find the major characteristics that influence the behavior of shear walls when subjected to earthquake loadings. The obtained analyt ical responses are compared with some existing test results. Maximum d isplacements, maximum reaction forces, energy dissipation, and frequen cy contents are the significant parameters used to compare the predict ions of each model with the experimental results. It was found that mo dels with stiffness degradation and pinching effects are the most suit able models for nailed joints.
