Abstract

To study epicenter intensity model of aftershock, regression analysis on 68 sets data of main shocks and their aftershocks have done, epicenter intensity linear model has researched. According to analysis of earthquake parameters such as peak ground acceleration (PGA), ground motion duration, spectrum intensity factor, they are reasonable to obtain aftershock parameters by appropriately reducing their main shocks'. Equivalent earthquake waves were formed by combining various main shock waves and their corresponding aftershock waves. Using elastic plastic time history analysis of some concrete filled steel tube (CFST) arch column structure, displacement and hysteretic energy indexes in different fortification intensity have obtained under main shock and equivalent earthquake. Using damage index correction coefficient, Park-Ang model was modified to evaluation structure damage which show damage index increased about 7%~20% by thinking of single strongest aftershock, and lower fortification intensity is, bigger damage index increase. Through the calculation of two software, the reliability of the model was verified.
