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。 -
More than 20 years reforming and opening of the shipping safety management was a process for recovering, improvement, reforming and enhancing the system of the shipping safety management. entering the new century, the shipping safety management faces a severe test and also meets a good development opportunities. the complexity, phase and reversal of the yangtze river ' s safety managemet determined it was important and urgent to seek establishment of a new system of water safety management
