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。以7条坚硬场地条件下的地震记录为输入,建立了适用于结构设计的屈服点谱,并且提出了基于YPS确定K型偏心支撑钢框架(EBF)屈服基底剪力的性态设计方法,对周边构件进行了能力设计。Yield point spectra（YPS） are a new response spectrum with the displacement acceleration format.A total of 7 ground motion records under the still soil site condition was selected to construct the YPS appropriate for the seismic design.The paper proposed the capacity design approach of performance,that is,the base shear of K-eccentrically braced steel frame was determined based on the YPS,and the design of elements surrounding of K-EBF was performed based on the capacity design approach.The reliability of this method was examined in the relative paper.
