On seismic design of pile-foundation-superstructure system by dynamic pushover analyses

（1）开发了能将桩-基础-上部结构作为一个系统进行分析的M-1程序，M-1程序是基于弹塑性模型的相对简单的质点-弹簧模型。地震运动从底部和侧面输入。（2）M-1模型可靠性分析程序的开发利用M-1模型，开发了可靠性分析程序。介绍了一种新的蒙特卡罗模拟技术MCMC。此外，有关地震运动的不确定性进行了评估。（3）结构体系的动力push-over分析本文介绍了结构体系的动力push-over分析方法，并给出了相应的研究结果。

This study includes the following three phases :(1)Development of M-1 program which is able to analyze pile-foundation-super structure as a system.M-1 program is relatively simple mass-spring model based on elasto-plastic model. The seismic motions are input from the base and the side.(2)Development of reliability analysis procedure by M-1 modelUsing M-1 model, reliability analysis procedure is developmed. New Monte Carlo simulation technique, MCMC, is introduced. Also, uncertainties concerning seismic motion are evaluated.(3)Dynamic push over analyses to evaluate the structure systemThe developed methods are introduced to analyze the reliability of the system.The results of the research are presented in the papers in the reference list.
