| 摘 要： | 改进能力谱法可以较好地评估结构抗震性能,在工程中得到了广泛的应用.本文在此基础上指出,由改进能力谱方法求得的延性是结构的延性需求,并不是结构的实际延性能力,不能以此代表结构在罕遇地震作用下的实际抗震能力.其次,基于弹塑性损伤反应谱(简称"RD谱"),结合模态Pushover分析,提出了基于RD谱的能力谱分析方法,通过R...

| Abstract: | Modified capacity spectra method(MCSM) can well access the performance of frame structures and is widely used in the actual engineering projects.The ductility of structure obtained by using MCSM is not the capacity of structure,but the demand.It can't stand for the actual seismic capacity of structure subjected to earthquake action.On the basis of inelastic damage spectra,denoted as RD spectra,a new CSM based on RD spectra is presented,called RCSM.The ductility obtained by using RCSM is the actual seismic c... |
