基于ABAQUS的墙板受压数值模拟

Numerical Simulation for Axial Compression of Wall Panel Based on ABAQUS

利用ABAQUS建立轴心受压墙板的有限元模型,模拟结果与试验结果吻合较好,论证了模型的正确性和可行性。通过在ABAQUS中建立墙板受压的模型,分析了分布钢筋的直径、混凝土的强度等级和混凝土面层的厚度对墙板轴心受压承载力和最大侧向位移的影响,结果表明:混凝土面层厚度对于承载力影响最大,混凝土强度等级影响次之,钢筋直径的影响最小。

ABAQUS was used to establish the finite element model of the axially compressed wall panel.The simulation results are in good agreement with the test results,which demonstrates the correctness and feasibility of the model.By establishing a compression model of the wall panel in ABAQUS,the influence of the diameter of the distributed steel bar,the strength grade of the concrete and the thickness of the concrete surface layer on the axial compression bearing capacity and the maximum lateral displacement of the wall panel is analyzed.The results show that concrete thickness of the surface layer has the greatest influence on the bearing capacity,followed by the concrete strength grade,and the steel bar diameter has the smallest influence.
