摘要:
为研究钢骨-方钢管高强混凝土组合柱小偏心受压力学性能,采用有限元软件ABAQUS对钢骨-方钢管高强混凝土组合柱小偏心受压试件进行非线性有限元分析,研究了长细比、偏心率、配骨指标和加载方向这些参数对组合柱小偏心受压力学性能的影响。通过回归分析提出小偏心受压承载力简化计算公式,并将简化公式计算结果与试验结果及有限元(FEM)计算结果进行对比。结果表明:长细比、偏心率对组合柱小偏心受压承载力影响较显著;配骨指标的增大能提高组合柱的延性;加载方向对承载力影响很小;简化公式计算结果与试验结果及有限元计算结果吻合良好。
Abstract:
In order to investigate mechanical properties of square steel tube filled with steel-reinforced high-strength concrete composite columns subjected to small eccentric compression, nonlinear finite element analysis of square steel tube filled with steel-reinforced high-strength concrete composite columns under small eccentric compression was conducted by the software ABAQUS. The effects of slenderness ratio, eccentricity, steel ratio and loading direction on the mechanical properties of composite column under small eccentric compression were analyzed. Simplified calculation formula was proposed, and simplified calculated results were compared with test results and FEM results. The results indicate that slenderness ratio and eccentricity ratio have significant impact on bearing capacity of composite column under small eccentric compression. Increasing of steel ratio can improve the ductility of the composite columns, and loading direction has small influence on bearing capacity. Calculation results of simplified formula are in well agreement with experimental results and FEM results.
