【摘要】 本文首先分析了偏心支撑钢框架中的关键构件———耗能连梁的弹塑性性能 ,提出了一种简化的屈服模型 ,并在此基础上编制一种新型的弹塑性时程分析程序。利用所编制的程序对两个典型算例进行了弹塑性时程分析 ,并对算例中偏心支撑框架和中心支撑框架两种结构的地震响应进行了比较。其结果表明 ,偏心支撑框架结构的地震响应要明显小于中心支撑框架结构的地震响应。更多还原

【Abstract】 In the first part,this paper analyses the elastic plastic behavior of active link, which is the key member of EBSF, and puts forward a kind of simplified model of yielding. Based on this, a new elastic plastic program for dynamic response analysis was made. With this new program, the inelastic dynamic response analysis of two typical structure examples were performed, and the anti seismic efficiency of EBSF and CBSF of examples were also compared in this paper. It is shown by result that the earthquake response of EBSF is lower than that of CBSF. [更多还原
