Comparison of the vulnerabilities between former and current RC frame structures after the 2008 Wenchuan earthquake are performed in the paper. Two representative types of RC frame building in Wenchuan county town are studied by nonlinear finite element method (FEM). Probabilistic seismic demand models (PSDM) for RC frame structures is built to assess the safety levels of two representative RC frames in Wenchuan county town. The fragility curves for immediate occupancy (IO), significant damage (SD), and collapse prevention (CP) damage levels of the RC frame building are analyzed. The result indicates the safety levels of current RC frame building in Wenchuan district are well improved compared to the former RC frame building after the 2008 Wenchuan earthquake.
