摘要

通过对1:2缩尺三层Y形高强钢组合偏心支撑框架结构（Y-HSS-EBF）模型试件的振动台试验，考察了结构的抗震性能。基于结构的恢复力模型与等代拉杆简化模型，采用SAP2000程序中的多线段塑性Kinematic连接单元代替拉杆，进行Y-HSS-EBF结构的地震反应简化分析，并将简化分析计算结果与试验结果、有限元计算结果进行了对比。研究结果表明：Y-HSS-EBF结构具有良好的抗震性能；由简化计算方法得到的Y-HSS-EBF结构滞回曲线与试验结果基本一致，简化分析模型能较好地模拟结构的非线性性能；振动台模型的简化计算结果具有一定的精度，简化分析模型能够较好的用于Y-HSS-EBF结构的弹性与弹塑性地震反应分析。在初步设计时，可采用简化分析模型对结构地震作用进行计算。

Abstract

Shaking table tests of a 1∶2 scaled three-story Y-type high strength steel composite eccentrically braced frame (Y-HSS-EBF) were conducted to study its a seismic behaviors.A simplified seismic response analysis method for Y-HSS-EBF was proposed by using the multi-linear plastic Kinematic element in SAP2000 to replace braces,based on the restoring force model of Y-HSS-EBF and the simplified model of the replacing braces.The calculated results with the simplified analysis method were compared with the test ones and those with the finite element analysis method.The results indicated that the Y-HSS-EBF has good aseismic performances; the calculated hysteresis curves of the Y-HSS-EBF agree well with the test ones and the simplified analysis model can be used for the strucfure’s performances nonlinear analysis; the simplified calculation results of the shaking table test model has a certain level accuracy, so the simplified analysis method can be used for analyzing elastic and elastoplastic seismic responses of Y-HSS-EBF; the simplified seismic response analysis method can be applied in the preliminary design of Y-HSS-EBF.
