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

Abstract

© 2019 IOP Publishing Ltd. All rights reserved. The article presents higher modes accounting method under estimation of 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 a complex of dynamic and static calculations was performed. It is established that proposed inertial forces modified system can significantly reduce system seismic resistance lack.
