摘　　要：采用有限元软件ANSYS分析了3种尺寸的混凝土夹芯承重墙板的轴向受压力学性能,并与试验结果进行了对比分析,结果表明,有限元计算的构件的荷载-应变曲线和极限荷载与试验值吻合,混凝土夹芯承重墙板在轴向荷载下首先在中部开裂,然后出现受压破坏。墙板中的钢丝网延缓了裂缝的出现,调整了板中内力的分布,增强了混凝土板的承压性能。Tbe compression mechanic performance of 3 concrete sandwich load-bearing panels under axial forces is studied using finite element analysis software ANSYS. The calculated results are compared with the tests, and it shows that the loadstrain curve and limit load accord with the test results. The cracks appear in the middle of the panel firstly and the panel damages because of the compression. The wire mesh in the sandwich panel delays the appearance of the cracks, and improves the compression performance of the concrete panel because it regulates the distribution of internal force in the panel.
