The main objective of this study is to define hysteretic model for deterministic nonlinear time-history analyses of Japanese conventional wood houses under various earthquake ground motion. Three hysteretic models are used to fit cyclic loading tests of walls. Their models are combination of elasto-plastic and slip model, Takeda model for reinforce concrete beam member and Magara model defined based on cyclic tests of wooden shear walls. Their applicability is confirmed from the comparison to pseudo dynamic tests. The maximum response is estimated within a range of twenty percent difference on every hysteretic model. Due to several cyclic loading, ductility is decreased in bracing wall therefore the maximum responses of bracing walls are overestimated. Residual displacements are not followed by every hysteretic model. The parameters of simple combination of elasto-plastic and slip model are proposed based on the structural design values and results of fitting of cyclic loading tests. The proposed model almost corresponds to the fitting model.
