摘　　要：基于平截面假定,以材料截面边界为计算单元,对15根钢骨混凝土L形截面柱进行非线性全过程数值分析。结论表明:钢骨混凝土L形截面柱截面曲率延性的最不利荷载角为155°,而且荷载角α,轴压比n,箍筋间距与纵筋直径之比s/d是影响钢骨混凝土L形截面双向压弯柱截面曲率延性的主要因素。Based on presumption of the plain cross section,the nonlinear full-range analysis is carried out for 15 steel reinforced concrete L-shaped columns（SRCLSC） whose sections are meshed by their edges.It is demonstrated that the least favorable ductility angle of SRCLSC is 155°,and the loading angle（α）,compression ratio（n）,and the ratio of the spaces between stirrups to the diameter of longitudinal reinforcements（s/d） are the principal influence factors in ductility of SRCLSC subjected to the biaxial eccentric compression.
