Development of Analytical Model for Three-dimensional Earthquake Response Analysis of Timber Structures and its Validation by Structural Experiments

将日本传统木结构的拟动力试验结果与集中质量模型和宏单元有限元模型的结果进行了比较。利用剪力墙开裂试验得到的剪力墙滞回参数进行了mss集中模型时程地震反应分析，利用单剪钉试验得到的钉缝滞回参数进行了有限元模型时程地震反应分析。结果表明，集总模型和有限元模型均能较好地预测结构在单向载荷作用下的响应。通过半比例模型拟动力试验，研究了剪力墙布置方式和横隔梁抗剪刚度对结构动力特性的影响。拟动力加载是在试件的对角线方向进行的，以便在两个方向上施加载荷。将试验结果与集中质量模型的模拟结果进行了对比，结果表明，当横隔梁剪切刚度较大时，模拟结果与试验结果吻合较好，而当横隔梁剪切刚度较小时，模拟结果低估了响应。

Pseudo-dynamic test results of Japanese conventional wooden structures were compared with the results of both lumped mass model and Finite element model with Macro element. Time history earthquake response analysis with lumped mss model was conducted by using the hysteresis parameters for shear walls obtained from the racking test of shear walls, and that with Finite element model were conducted by using hysteresis parameters of nail joint obtained from the single shear nail test. It was proved that the simulation by both lumped model and Finite element model predicted well the response of the structure in case of one direction loading. Pseudo-dynamic test was conducted on half scale model and the effect of shear wall layout and the shear stiffness of horizontal diaphragm. Pseudo-dynamic loading was conducted in the diagonal direction of specimen in order to apply the loads in two directions. Test results were compared with the simulation by lumped mass model, and it proved that the simulation showed comparatively good agreement with the experimental results when the shear stiffness of horizontal diaphragm is comparatively high but it under estimate the response when that is small.
