Research on Performance-Based Design Method of RC Structure

Abstract

Three level and two stage design method is the main seismic design of China, which has continued to use until now. However, the design method lacks specific quantitative performance index of the Reinforced concrete (RC) structure. Comparing with the present internationally advanced performance-based seismic design method, the design method has still a certain gap. In order to develop the performance-based design method at domestic, it is necessary to carry on the refinement to China's performance level of RC structure and quantify essential performance index under different seismic level. In the paper, seismic levels are divided into four seismic levels performance levels of RC structure are divided into four run phase. And then, the story drift angle limit of RC structure in the four run phase is quantified.
