Seismic resistance evaluation of high-rising structures under ductility level earthquake by nonlinear static method

Abstract

Multimodal nonlinear static method for the high-rising structures’ seismic resistance evaluation has been considered in this article. The object of the study is 80-meters high wind power plant. The method for account of the higher vibrations’ modes and characteristic point search modified algorithm have been offered. For results verification of the systems under ductility level earthquake the nonlinear time history analysis has been performed. According to the comparative analysis the results difference between two methods does not exceed 12%.
