SEISMIC BEHAVIOR OF A NEW HIGHRISE SHEAR WALL WITH SEISMIC ENERGY DISSIPATION MECHANISM

本文根据两个十层新型抗震耗能剪力墙结构模型的振动台试验结果,研究了这种结构的地震反应、变形特性和耗能机理,提出了进行非线性地震反应分析的计算模型,并与试验结果进行了对比,在此基础上进行了参数研究,分析了结构主要参数的变化对抗震性能的影响。

Based on shaking table tests of a new highrise shear wall structure, a dynamic analytical model of frame method with wide columns and rigid beams was developed for the nonlinear seismic response analysis of the shear walls. In this analytical model, the nonlinear behavior of the connecting beams and the local deformation of the beam-wall joints are taken into account. The results of shaking table test were used to verify this analytical model, and good agreements between test and analysis were obtained. By using this model, the seismic response, deformation characteristics and energy dissipation mechanism of the new shear walls were studied, and the effect of structural parameters on the seismic behavior of the shear walls was analyzed as well.
