摘　　要：异形柱与矩形柱相比有明显的优势。为了研究L形混凝土偏心受压柱的性能,采用非线性有限元软件ABAQUS,对其受力性能进行模拟分析。建立了L形混凝土柱的有限元模型,计算值与试验值吻合较好。利用该模型研究了偏心距、荷载加载角度,对L形混凝土偏心受压柱受力性能的影响。结果表明偏心距及荷载加载角度对L形混凝土柱受力性能均影响较大。Special-shaped columns have obvious advantages compare to rectangular columns.In order to study the performance of L shape eccentrically compressed concrete column,this research adopted the nonlinear finite element software ABAQUS to simulate and analyze its mechanical properties.A finite element model of L shaped concrete columns was developed,the calculation results agree well with the experimental results.The effects of eccentricity,loading angle to the L shaped concrete eccentric compression columns were investigated by using the model.The results show that the eccentricity and the loading angle has great influence on the stress performance of L shaped concrete column.
