本研究的主要目的是为日本传统木结构房屋在各种地震作用下的确定性非线性时程分析定义滞回模型。在第一部分的报告中，三个模型，弹塑性和滑移相结合的模型，钢筋混凝土梁构件的武田模型和Magara模型进行了比较，以确认的适用性。本文提出了基于演化参数滞回模型的修正模型。修改内容如下：A）考虑循环荷载作用下骨架曲线的退化，B）考虑正、负位移的退化。通过与稳定位移循环试验、拟动力试验等试验结果的对比，验证了模型的适用性。
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. In part 1 report, three models which are combination of elasto-plastic and slip model, Takeda model for reinforce concrete beam member and Magara model are compared to confirm the applicability. In this study, the modified model based on Evolutionary Parameter Hysteretic Model is proposed. The modifications are: A) Reloading and unloading path is revised to fit with the result of cyclic loading tests, B) Consideration of degradation of backbone curve due to the cyclic loading, C) Consideration of degradation of plus or minus displacement. The comparison of the model and tests, which are stable displacement cyclic test, pseudo dynamic test and so on proofs the applicability of proposed model.
