| Abstract: | In this paper, a refined Comp P element model is presented to describe the development and distributing of plasticity in a steel frame, as well as the appearing sequence of plastic hinges,the P-δ effect and the P-Δ effect.Deformations under all kinds of loads can also be well reflected.Moreover,it can model the steel structure with the permission of single element per member, so that non linear dynamic analysis for large structure can be well performed. |
