Abstract

Here,16 strong ground motion records for Ms 7.0 Lushan and Jiuzhaigou Earthquakes were selected with screening conditions of epi-central distance being less than 55 km and PGA being larger than or equal to 50 gal. 41 kinds of ground motion intensity parameters and accumulative kinetic energy curves based on V2 time-frequency response spectrum (V2TFRS) were extracted from each of the selected records. 111 lumped mass simplified models were established to do elastoplastic time history analyses with the selected 16 records taken as inputs,and extract the maximum inter-story drift angle and the maximum peak floor acceleration at the lumped mass of each building. Taking the limit value of inter-story drift angle as a building’s damage state parameter,damage states of 111 buildings under the action of each of the 16 selected records were obtained. Through comparing 41kinds of ground motion intensity parameters and accumulative kinetic energy curves based on V2TFRS of Ms 7.0 Lushan and Jiuzhangou earthquakes’ground motion records as well as damage states of 111 buildings,the reason why Jiuzhaigou earthquake had a smaller destructive capacity than Lushan earthquake did was described quantitatively to provide a basis for scientifically analyzing the disaster difference between Lushan earthquake and Jiuzhaigou one.

Key words

Lushan earthquake / Jiuzhangou earthquake / ground motion intensity parameters / accumulative kinetic energy curve / structural damage state
