| 摘 要： | 屈服点谱(Yield Point Spectra,YPS)是一种新的等延性位移-加速度反应谱,可用于结构的抗震性态设计及评估。给出了基于YPS的结构抗震性态评估方法,选取了两个按我国现行规范设计的偏心支撑钢框架算例,将由YPS法得出的结构顶部峰值位移、层间位移角与弹塑性时程分析的结果进行了对比,对比结果评价了YPS法用于偏心支撑钢框架性态评估的可信性。 |
| 关 键 词： | 屈服点谱 偏心支撑钢框架 顶部峰值位移 层间位移角 性态评估 |

| Abstract: | Yield point spectra(YPS),a new response spectrum with the constant-ductility displacement-acceleration,can be applied to the seismic performance design and evaluation of the construction.The paper introduces a construction seismic evaluation using YPS,which takes two eccentrically braced steel frames designed by the current Chinese specifications as an example,and then makes a contrast between the peak displacement and interstory drift indices(IDI) by YPS.The result evaluates the credibility of YPS method a... |
