Abstract:The two-level seismic design methodology for reinforced concrete(RC) building structures in Japan is introduced. The design method of level 2 corresponding to severe earthquake is presented, which included the acceptable design index, the definition of the earthquake force, the design of failure mechanism for the structure, and the ensuring design of structures-failure mechanism. The corresponding analysis method, axial force limit of RC columns, concrete and steel strength value and the performance the non-structural element under the second level earthquake intensity are introduced. The method is helpful for developing a methodology to conduct quantitative anti-collapse seismic design for RC buildings under severe earthquake in China.

Keywords:reinforced concrete structure; seismic design; severe earthquake; failure mechanism; axial force ratio limit
