中空混凝土外墙的强度数值模拟研究

NUMERICAL SIMULATION OF STRENGTH OF HOLLOW CONCRETE EXTERIOR WALL

为进一步加强对中空混凝土外墙的强度研究,通过ANSYS/LS-dyna软件,分析了中空混凝土外墙的材料本构关系,对中空混凝土外墙的三维数值模拟模型进行构建,发现随着荷载的增大,斜裂缝继续向上延伸,当施加荷载为625kN时,最大拉伸损伤程度达到0.9341,表明外墙破坏严重,最后通过结果对比,进一步验证了建立仿真模型的可靠性及合理性。

In order to further strengthen the research on the strength of the external wall of hollow concrete,this paper analyzed the material constitutive relationship of the external wall of hollow concrete by using ANSYS/LS-dyna software,and built a three-dimensional numerical simulation model of the external wall of hollow concrete.It was found that with the increase of load,the oblique crack continued to extend upward.The maximum tensile damage degree reached 0.9341,indicating that the external wall was seriously damaged and the external wall had been damaged.Finally,the reliability and rationality of the simulation model are further verified by comparing the results with the experimental results.
