The results show that we can get actual velocity and displacement time histories by simulating broadband acceleration records. The acceleration and displacement time histories also may be obtained by simulating broadband velocity records. This indicates that strong motion observations and seismometer observations can be substituted for each other in a certain range.展开更多
