轴向力对剪切钢板阻尼器抗震性能影响的数值模拟
Numerical Simulation on Seismic Performance of Shear Steel Panel Damper Under Axial Force
摘要
Abstract
Using the numerical simulation method,the seismic performence of shear steel panel damper under the axial force is studied,through 5 different groups of shear steel panel damper,the effects of the depth width ratio and the depth thickness ratio on the damper are discussed,and 2 types of axially free new shear steel plate dampers are proposed.The results show that the axial force has adverse effect on the damper seismic perfor-mence,the local buckling on web occurs more easily,and the degree of buckling is greater.It is necessary to take the anti-buckling measures.The yield load,the ultimate load,the initial stiffness and the post yield stiff-ness decrease significantly with the increase of the depth width ratio and the depth thickness ratio.When the depth of the web remains unchanged,increasing the width or thickness of the web can effectively improve the seismic performence of the damper.关键词
