A lateral load distribution for the static analysis of base-isolated building frames under the effect of far-fault and near-fault ground motions

This paper attempts to examine the effect of the scaling of ground motion records on the seismic responses of base-isolated buildings by using the three scaling methods including the ASCE 7–10, acceleration spectrum intensity, SIa, and the spectral acceleration corresponding to the effective period of the base-isolated structure at the design displacement, Sa(TD). The buildings had steel moment-resisting and X-braced systems and were isolated...
