Account for the contribution of higher vibration modes under seismic resistance estimation of system with elastomeric supports by nonlinear static method

Abstract

The article presents higher vibration modes accounting method to evaluate system seismic resistance by nonlinear static method. As part of the study, in order to verify the proposed method for finding the inertial forces modified system series of dynamic and static calculations was performed. Proposed inertial forces modified system can be applied for seismic resistance estimation of system with elastomeric supports. The results difference varies within 12%. © 2020 Published under licence by IOP Publishing Ltd.
