荷载作用下人字撑复合板的有限元分析

Finite element analysis of herringbone composite plate under load

基于有限元软件ABAQUS,建立混凝土外边框内置人字撑的泡沫混凝土复合板模型,对其施加荷载竖向荷载和水平荷载,数值模拟计算复合板外边框、人字撑及泡沫混凝土的应力、位移,分析其受力性能及破坏形态.对比分析不同荷载作用下结构的应力、应变和位移云图,混凝土外边框、人字撑、泡沫混凝土分级承担荷载,结构各部分协同工作效果显著.

Based on the finite element software ABAQUS,a foam concrete composite panel model with built-in herringbone on the outer frame of the concrete was built,and the vertical load and horizontal load were applied to the load.The numerical simulation was used to calculate the stress and strain of the outer frame of the composite panel,the herringbone and the foam concrete.And displacement,analysis of its force performance and failure mode.The stress,strain and displacement cloud diagrams of the structures under different loads are compared and analyzed. The concrete outer frame,herringbone and foam concrete are graded to bear the load,and the joint work of each part of the structure is remarkable.
