The influence of ductility, rigidity and strength of each member on the overall response behavior of R/C frame structures has hardly been clarified. The objectives of this research are to make a program of a response analysis for R/C frame structures based on ductility of all members and to establish the appropriate arrangement of ductility factor for all members of two-story R/C bridge piers as an earthquake-resistant structure.Using the restoring force model which can show ductility of each member, dynamic response analysis based on one component model was developed. Pseudodynamic tests were carried out to improve the accuracy of the program. The overall response behavior of two-story R/C bridge piers can be calculated accurately by using the restoring force model which can represent ductility factor in all members even if the load carrying capacity of some members decreased suddenly due to the occurrence of shear failure. To keep the two-story R/C bridge piers ductile when subjected to earthquakes, it was calculated how much ductility is needed in each member.

几乎没有阐明延性，刚度和强度对R/C框架结构总体反应行为的影响。这项研究的目的是根据所有成员的延展性制定R/C框架结构的响应分析程序，并为所有两层R/C桥墩的所有成员建立适当的延展性因子的布置，作为抗震抗性的结构。使用每个成员的延展性模型，基于一个组件模型的动态响应分析，都可以开发出一种恢复力模型。进行伪动力测试以提高程序的准确性。可以通过使用恢复力模型准确地计算两层R/C桥墩的总体响应行为，该模型即使某些成员的负载能力突然降低，该模型可以代表所有成员的延展性因子，即使剪切故障的发生突然降低。为了在发生地震时保持两层楼的R/C桥墩的延展性，可以计算每个成员需要多少延展性。
