PERFORMANCE-BASED SEISMIC FORTIFICATION CRITERION AND QUANTIFIED PERFORMANCE INDEX OF RC FRAME STRUCTURE
In China seismic design codes, the gap in probability of exceedance between frequent earthquake and extremely rare earthquake is very large, therefore, a new definition of occasional earthquake and two new structure performance levels in more detail are bring forward to form a four level seismic fortification criterion. Then five structure performance levels and fourteen structure performance objects which are ranked to three groups are established. Based on the statistical data of two hundred and fifteen seismic performance test of reinforce concrete frame or columns, two index of temporarily operational and reparably operational performance levels are put forward. By using nonlinear static analysis and time-history analysis methods, examples are presented to demonstrate that buildings satisfied the fully operational level under frequent earthquake is not ensure to be in temporarily operational level or reparably operational level under rare earthquake. If the frequent earthquake is substituted by the occasional earthquake, the problem above can be solved well.
