Based on behavior of joint core under cyclic reversal load , according to actual measurement load - displacement hysteresis loops , slip of longitudinal reinforcement passing through joint and shear deformation of joint in a serial of beam - column subassemblage tests , the typical slip hysteresis model of longitudinal reinforcement passing through joint and typical shear deformation hysteresis model of joint are proposed in this paper
本文以节点的受力特性及规律为基础，基于若干梁柱组合体低周交变加载试验的实测节点恢复力滞回曲线以及从中分离出来的贯穿节点的梁筋滑移变形结果、节点剪切变形结果，分析总结得到有一定代表性的梁端剪力与贯穿节点梁筋滑移之间和梁端剪力与节点剪切变形之间的滞回关系模型。
3. Several important conclusions are gained by the analysis of push - over method and quasi - static reversal load pattern to a reinforced concrete structure : under the two earthquakes , the responses of structure are more serious than the responses under single earthquake , by the conclusion , it is not rationality that structure ' s earthquake damage prediction under single earthquake ; the main - after earthquake action is different from fore - main earthquake action under the same earthquake magnitude combination ; the push - over analysis to the structure is convenient and utility , it also reflects the response and performance of structure under the earthquake , so the method ' s development future is wide . based on the research of the former scholars , some means of structure resisting earthquake are introduced in the last part of this thesis , and the result of earthquake damage prediction for the planning area of quanzhou city is given
通过对一钢筋混凝土结构进行push - over分析与拟静力循环往复加载分析，得到了一些重要结论：在两次地震动作用下，结构物的反应比仅考虑一次地震动作用时的反应要严重的多，从而说明传统上仅仅考虑一次地震动作用的建筑物震害预测是不合理的：即使在同震级组合的两次地震作用下，前震主震型、主震余震型地震对结构物产生的破坏作用也是不尽相同的；对结构物进行静力弹塑性分析的方法( push - over方法)简便实用，并能较准确地反映大震下结构的一般性能和反应，再一次的证明了该方法具有广阔的发展前景；根据前人的研究成果，在本文的最后，简单的介绍了一些结构物抵御多次地震破坏作用的方法，并给出了泉州市规划区内钢筋混凝土框架结构群体震害预测的结果。
4. The inelastic demand spectra are established according to the new chinese seismic design code for buildings by means of force reduction factor r and ductility factor u , thus , a simple and practical method is established for seismic damage assessment in combination with capacity spectrum method ; the structure ' s push - over curve of second earthquake is gained by cutting the curve of quasi - test reversal load pattern method , thus , the structure ' s cumulate damage level can be computed by the capacity spectrum method too ; the results of an example are compared with the facts , and the validity and simplicity of this method is approved
利用r -关系基于抗震规范弹性反应谱建立了能力谱方法中的需求谱，并将该法和能力谱方法结合，建立了一种简单实用的结构损伤评估方法；对拟静力循环往复加载曲线的截取，得到了第二次地震作用的push - over曲线，从而能够继续使用能力谱方法得到结构物的累积损伤值；通过算例阐述了该法的计算步骤，所得结果符合基本规律，且具有概念明确、简单实用的优点。
