摘要

依托ABAQUS有限元分析软件,以"一"字形短肢剪力墙较薄弱的抗震构件作为研究对象,建立等效模型并模拟分析了该结构在不同轴压比、不同钢筋配筋率情况下的承载、骨架曲线等关键抗震性能指标,并与试验结果进行了对比,得出了轴压比和配筋率对暗支撑"一"字形短肢剪力墙的抗震性能影响敏度较高的结论。
The paper investigates the relatively weak seismic system components of I-shaped short pier shear wall based on ABAQUS software.The components' equivalent model are established,which are used to analyze their key seismic specification such as bearing capacity and skeleton curve,under different axial compression ratio and reinforcement proportion of the concealed bracings. Comparison of simulation results and experiments indicates that axial compression ratio and reinforcement proportion of the concealed bracings are main factors that influence the seismic specification of I-shaped short pier shear wall.
