Abstract
A generalized numerical scheme for nonlinear analysis of framed structures is presented. The proposed numerical technique is aimed at improving the reliability and efficiency of a computer program for nonlinear analysis of structures exhibiting a limit or a bifurcation point. A simple and automatic energy method for the transformation of a bifurcation point to a limit point for the tracing of the realistic post-buckling path is also suggested. The combined numerical strategy proposed in this paper and recommended for general non-linear problems will greatly enhance the feasibility and user-friendliness of a nonlinear analysis computer program for general users.
