摘　　要：以钢筋混凝土梁设计原理作为依据,给出了L形截面钢管混凝土异形柱正截面的非线性分析方法。根据基本假定建立了L形截面钢管混凝土异形柱截面弯矩-曲率关系计算公式,并利用MATLAB语言编制了求解程序,根据得到的加载-破坏全过程弯矩-曲率关系分析构件的加载-变形特性。利用程序对不同截面、混凝土标号、钢材强度和钢管面积下的弯矩-曲率曲线进行了对比分析。Based on the design principle of reinforced concrete beam, a nonlinear analysis method of normal section of L - type concrete - filled steel tubular special - shaped column is presented. According to the plane hypothesis, a numerical solution about moment - curvature curve for L - type concrete - filled steel tubular special - shaped col- umn was presented, together with software programmed with matlab language. It is expected that loading - deforma- tion exhibition could be comprehensive grasped from the curves. Using moment - curvature curve of different section, concrete strength, the software to compare and analyse the ben- steel strength and steel tubular area.
