摘　　要：讨论了异形柱结构体系中Ｌ形截面柱在结构中的受力性能，指出Ｌ形柱是截面不对称的空间杆件，不能在两个主平面内分开考虑，无法在结构分析中用对称截面的矩形柱等效，Ｌ形截面柱在无扭转结构中截面的中性轴平行于工程轴。In this paper ,the behavior of reinforced concrete L shaped column is analysed. It is ex- plained that the L shaped co1umn is a three-dimensional member with non-symmetry section. It is not reasonable to separataly analyse the behavior in the two main plan.In the structural analysis the L shaped column can not be equivalent to the rectangular columns. In the structure with no rotation, the neutral axis of L shaped column is parallel to its engineering axis.

关 键 词：异形柱结构 L形截面柱 中性轴 钢筋混凝土 框架结构
