摘要
通过ABAQUS建立有限元分析模型,对配筋高强钢管高强混凝土轴压短柱的抗压性能进行研究,考察了箍筋间距对构件承载力的影响。分析结果表明,配置钢筋可以改善方钢管对核心混凝土的约束作用,增加高强钢管高强混凝土的承载力,改善其变形性能;随着箍筋间距的减小,构件的承载力增加。
Software of finite element analysis ABAQUS was used to study the compressive behavior of short column consisting of reinforced high strength concrete filled with high strength square steel tube(R-HCHSST)short column.The effect of stirrup spacing on the bearing capacity of R-HCHSST short column was studied.The analysis result indicated that the stirrup can improve the restraining effect of the square steel pipe on the core concrete,increase the bearing capacity of the R-HCHSST,and improve its deformation performance.With the decrease of the stirrup spacing,the bearing capacity of the R-HCHSST short column increases.
