| 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。 |
| 关 键 词： | 钢骨混凝土L形截面柱 非线性全过程分析 最不利荷载角 |

| Abstract: | 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. |
| Keywords: | steel reinforced concrete L-shaped columns nonlinear full-range analysis least favorable ductility angle |
