【摘要】 采用Abaqus软件建立L形柱的三维非线性有限元模型,分析了L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:加载角为135°时,承载力是最大的,延性良好;加载角为225°时,承载力是最小的,延性也最差;加载角为0°时,延性是最好的。更多还原

【Abstract】 By adopting the Abaqus,the bearing capacity and the ductility of L-shaped column under different loading angles were calculated by builting up the three dimensional finite element model of L-shaped column.The calculation results were in agreement with the experimental data.Some conclusions as follows have been reached: it is of the maximum bearing capacity and the good ductility when the loading angle is 135 degrees,which it is of the minimum bearing capacity and the worst ductility when the loading angle is 225 degrees and the best ductility when the loading angle is 0 degrees.更多还原
