The research results of this project title are summarized as follows:1. Strong ground motion and ground condition characteristics were estimated based on the recorded accelerograms on the rock site of the Osaka northern area2. Strong ground motions on the surface were generated for SH waves using the stochastic amplification technique3. Ground motions for SH wave were estimated introducing the Riccati method to the seismic response analysis of alluvial valley with irregular boundaries4. The random input ground motion models were shown using the parameters, which prescribe the non-stationary processes on the basis of the recorded ground motions5. The reiationship between the restoring force models and earthquake damage modes of wooden houses was examined using the typicai recorded strong ground motions.6. Earthquake response characteristics were shown of wooden-framed houses with the restoring force characteristics having both hysteretic and slip types and with the non-linear rotational springs at the top and the bottom of the columns7. The relationship between the horizontal stiffiless on the basis of the wall-ratio of the wooden house and the stifihess of the non-structural factor was made clear, and the total stiffiless ofthe house couid be estimated8. Optimum seismic response control of structural systems was, estimated in case of the Maxwell-type non-linear viscous damper. It have been recognized that this system will be able to be applied to wooden houses9. The wall arrangement affects the torsional oscillation of wooden houses. The fundamental data couid be gotten on the good wall arrange and the design to control the tosional oscillation10. It is shown that the earthquake damage will be able to be predicted from the earthquake response analysis results of wooden houses for the various levels ofthe input ground motions

该项目标题的研究结果总结如下：1。根据大阪北部地区的岩石部位的记录加速度图估算了强的地面运动和地面条件特征。使用随机扩增技术生成了表面上的强大地面运动3。估计SH波的地面运动，将Riccati方法引入了具有不规则边界的冲积谷的地震反应分析4。使用参数显示随机输入地面运动模型，该参数根据记录的接地运动规定非平稳过程5。使用典型的地面运动检查了恢复力模型与木制房屋的地震破坏模式之间的重新服装。6。地震响应特征显示出具有具有滞后和滑动类型的恢复力特征以及列的顶部和底部的非线性旋转弹簧。在木屋的壁比和非结构因素的Stifihess的基础上，水平僵硬之间的关系清楚了，估计房屋的总僵硬量为8。在麦克斯韦型非线性粘性阻尼器的情况下，估计结构系统的最佳地震反应控制。已经认识到，该系统将能够应用于木制房屋9。墙面排列会影响木制房屋的扭转振荡。基本数据可以在良好的墙壁安排和设计中，以控制Tosional Oscillation1010。结果表明，地震损害将能够从木制房屋的地震响应分析结果中预测到各种输入地面运动的结果
