摘　　要：为研究轴压比对T形钢管束混凝土组合剪力墙抗震性能的影响,本文运用数值模拟软件ABAQUS设计并建立了轴压比为0、0.1、0.2、0.3、0.4、0.5、0.6、0.7、0.8的九个试件,进行有限元分析,系统分析了试件的抗震性能。分析结果表明:随着轴压比增大,T形钢管束混凝土组合剪力墙的承载能力有所降低,耗能能力有所提高;当轴压比大于0.6时,初始刚度显著降低。To study the influence of axial compression ratio on the seismic performance of T-shaped composite shear wall with steel tubes and concrete,this paper uses ABAQUS to design and establish nine specimens with axial ratios of 0、0.1、0.2、0.3、0.4、0.5、0.6、0.7、0.8.Finite element analysis was conducted to systematically analyze the seismic performance of the specimens.The analysis results show that as the axial compression ratio increases,the bearing capacity of the T-shaped composite shear wall with steel tubes and concrete decreases and the energy dissipation capacity increases;When the axial compression ratio is greater than 0.6,the initial stiffness significantly decreases.
