Abstract

The effects of input parameters of pulse-like ground motions on the response of soil–structure systems are investigated through employing an ensemble of 64 ground motions. The soil and superstructure are idealised as a semi-infinite cone and a non-linear multiple-degrees-of-freedom shear building, respectively. The results confirm that the location of the critical storey is significantly affected by the pulse inputs and interacting parameters. Also, the pulse period ranges in which the critical storey complies with upper storeys are influenced considerably by interacting parameters. Moreover, there is a trade-off between pulse period and amplitude to determine the seismic demands of the structure.
