摘要
采用Abaqus软件建立十字形柱的三维非线性有限元模型,分析了十字形柱在不同加载角下的承载力与延性,计算结果与试验值符合良好,分析表明:在加载角为0°和45°时,承载力和延性都相差不大;加载角为45°时,承载力稍大;加载角为0°时,延性稍好。
By adopting Abaqus software,the bearing capacity and the ductility of +-shaped column under different loading angles were calculated by building up three dimensional finite element model of +-shaped column.The calculation results are in complete agreement with the experimental data.Following conclusions are made: they are the minor difference in bearing capacity and ductility when the loading angle is 0 degrees and 45 degrees,which is a little larger bearing capacity when the loading angle is 45 degrees and a slightly better ductility when the loading angle is 0 degrees.
