Abstract
This paper presents hysteretic model for deterministic nonlinear time-history analysis of Japanese conventional wood houses under various earthquake ground motions including motions after main shock. The model based on Evolutionary Parameter Hysteretic Model was proposed in the part 2 and in this paper the model was slightly modified to trace the maximum response of shaking table tests for two story houses. The modifications are 1) small displacement within 1/120rad. is ignored in deterioration of cyclic loading 2) damage in the minus displacement where reach in the arbitrary point is considered in the plus side. The arbitrary points are decided in accordance with the displacement at the maximum load of shear wall. For example, the displacement of plywood is 1/30rad and that of racing is 1/45rad. Normalized backbone curve is also proposed obtained from load-displacement relationships of ten shaking table tests. The maximum responses calculated from the time history analysis accord with the test result under sever earthquakes including the motion after main shock.
