In view of the differences between Chinese and Indonesia seismic design specification,we compare the parameters of design earthquake,site classification and design acceleration response spectrum.The results show that the horizontal length of Indonesia specification acceleration response spectrum curve is longer than that of Chinese specification in macroseismic area,and the peak value of acceleration response spectrum curve is larger than that of maximum seismic fortification intensity in Chinese specification.Basing on a high-pile wharf project,we analyze the differences of seismic effect in different specifications of the same site soil by ANSYS software and response spectrum method of mode decomposition,which can provide references for the similar projects.
