摘要
本文提出了钢筋混凝土耗能减振结构地震反应和损伤分析的简化方法。首先给出了考虑轴力变化效应 的耗能减振结构Ｐｉｓｈｏｖｅｒ分析方法，以及结构等价阻尼比ξ的计算公式；其次，结合文献［１２］中提出的“三 水准”地震损伤性能目标，提出了耗能减振结构基于能力谱法的地震反应、损伤分析与性能设计方法；最 后，对一座设置金属屈服型耗能器的四层钢筋混凝土框架结构进行了地震反应和损伤分析．
In this paper. simplified method of seismic damage and response analysis is put forward for reinforced concrete structures with passive energy dssipators. Firstly, the analysis procedure is given which takes axial force variability effect into account. And, the formulae of equivalent viscous damping ratio ξ are also provided. Secondly, by the three level seismic damage performance objec- tives suggested in reference [12], the capacity -spectrum-based method for the structures with passive energy dissipa...
