Two programs were developed in the study. One is based on classic plastic hinge assumption, the other is based on the whole section yielding assumption which considered the combined effects of moment, shear ,and axial force. Study about the ductility of different system was made by using these two programs.Three structure systems were included, which are ductile frames,concentric bracing systems, and eccentric bracing systems. The other studied parameters include the column-to-beam stiffness ratio, and the way to use bracings. The results were presented by the displacement ratios, force ratios, and the ductility ratios. The results show that the classic method will overestimate the structure ductility. There fore it is dangerous to use the classic method to analyze structure buildings. The structure model based on the whole section yielding is more reasonable and precise in plastic analysis.
