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

本课题的研究成果总结如下：1。根据大阪北部地区岩石遗址的加速度记录，估计了强地震动和地面条件特征。利用随机放大技术对地表SH波产生了强烈的地面运动。将Riccati法引入不规则边界冲积河谷的地震反应分析中，对SH波的地震动进行了估计。随机输入的地震动模型用这些参数表示，这些参数规定了在记录地震动的基础上的非平稳过程5。利用典型的强地震动记录，研究了木质房屋的恢复力模型与地震破坏模式之间的关系。显示了木结构房屋的地震反应特征，具有滞回和滑移类型的恢复力特征，柱的顶部和底部具有非线性旋转弹簧7。明确了基于墙比计算的水平刚度与非结构因素刚度的关系，从而估算出了房屋的总刚度。在麦克斯韦型非线性粘性阻尼器的情况下，估计了结构体系的最优地震响应控制。人们已经认识到，这一系统将能够应用于木制房屋。墙体布置对木结构房屋的扭振有影响。得到了良好的壁面布置和控制扭振设计的基本数据。结果表明，在不同程度的地震动输入条件下，由木结构的地震反应分析结果可以预测木结构的震害
