轴压比对轻钢-泡沫混凝土组合墙体抗震性能影响的有限元分析

Finite element analysis on influence of axial compression ratio on seismic performance of lightweight steel-foam concrete composite wall

本文采用ABAQUS软件对轻钢-泡沫混凝土组合墙体进行了有限元模拟,分析轴压比对轻钢-泡沫混凝土组合墙体抗震性能的影响.结果表明,当轴压比在0.2~0.3的范围内时,随着轴压比的增加,试件的承载能力提高,变形能力降低;轴压比达到0.4时,各项指标成相反趋势发展.

In this paper,the finite element simulation of light steel-foam concrete composite wall was carried out by ABAQUS software,and the influence of axial compression ratio on the seismic performance of lightweight steel-foam concrete composite wall was analyzed.The results show that when the axial compression ratio is in the range of 0.2 to 0.3,the bearing capacity of the specimen increases and the deformation capacity decreases with the increase of the axial compression ratio.When the axial compression ratio reaches 0.4,the indexes develop in opposite directions.
