【摘要】 有限元分析可以作为试验的补充手段,模拟型钢混凝土构件的整个受力和变形过程。为了探讨轴压比和钢骨率的变化对SRC柱的延性和承载力的影响,利用有限元分析软件ABAQUS对型钢混凝土(SRC)柱的受力性能进行了非线性数值分析。为验证分析模型的合理性,首先利用已有的试验数据,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,通过对比荷载-位移曲线,验证有限元分析的有效性和准确性。通过建立具有不同轴压比和钢骨率的两组模型,分析了轴压比和钢骨率对构件力学性能的影响,为工程应用提供参考依据。更多还原

【Abstract】 Finite element analysis could be used as a supplementary means to investigate mechanical behavior.ABAQUS software are conducted to analyze steel reinforced concrete(SRC)columns.Firstly,in order to validate the rationality of the analytical model,finite element models of test specimens are established to simulate the test process.By comparing the analytical results with experimental ones,it is found that the results from finite element analysis coincide well with that from test.So ABAQUS software could be used as a supplementary means to simulate SRC column mechanical behavior.Further the ductility and ultimate capacity of SRC columns are studied with the changes of steel bone ratio and the axial compressive ratio.更多还原
