利用有限元分析软件ABAQUS对型钢再生混凝土(SRRAC)柱的受力性能进行了非线性数值分析。建立试件的有限元模型,对试验全过程进行非线性数值模拟,通过对比试验结果的荷载-位移曲线,分析了轴压比和再生骨料取代率对构件力学性能的影响,数值分析结果与试验结果吻合较好,表明有限元分析可以作为试验手段的有效补充,较好地模拟型钢再生混凝土柱的整个受力和变形过程。
The finite element analysis software ABAQUS was used to conduct nonlinear numerical analysis of the SRRAC columns. The finite element model of the specimen was established, and the whole process of the experiment was simulated by nonlinear method. The load-displacement curve of the test results was used to analyze the influence of the axial compression ratio and the recycled aggregate substitution rate on the mechanical properties of the member. The experimental results agree well with each other, which shows that the finite element analysis can be used as an effective complement to test methods to simulate the whole process of stress and deformation of SRC columns.
