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
本文以節點的受力特性及規律為基礎，基於若干樑柱組合體低周交變加載試驗的實測節點恢復力滯回曲線以及從中分離出來的貫穿節點的梁筋滑移變形結果、節點剪切變形結果，分析總結得到有一定代表性的梁端剪力與貫穿節點梁筋滑移之間和梁端剪力與節點剪切變形之間的滯回關系模型。 -
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 -關系基於抗震規范彈性反應譜建立了能力譜方法中的需求譜，並將該法和能力譜方法結合，建立了一種簡單實用的結構損傷評估方法；對擬靜力循環往復加載曲線的截取，得到了第二次地震作用的push - over曲線，從而能夠繼續使用能力譜方法得到結構物的累積損傷值；通過算例闡述了該法的計算步驟，所得結果符合基本規律，且具有概念明確、簡單實用的優點。 -
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
通過對一鋼筋混凝土結構進行push - over分析與擬靜力循環往復加載分析，得到了一些重要結論：在兩次地震動作用下，結構物的反應比僅考慮一次地震動作用時的反應要嚴重的多，從而說明傳統上僅僅考慮一次地震動作用的建築物震害預測是不合理的：即使在同震級組合的兩次地震作用下，前震主震型、主震餘震型地震對結構物產生的破壞作用也是不盡相同的；對結構物進行靜力彈塑性分析的方法（ push - over方法）簡便實用，並能較準確地反映大震下結構的一般性能和反應，再一次的證明了該方法具有廣闊的發展前景；根據前人的研究成果，在本文的最後，簡單的介紹了一些結構物抵禦多次地震破壞作用的方法，並給出了泉州市規劃區內鋼筋混凝土框架結構群體震害預測的結果。
