Modal decomposition spectrum method for structure's energy response

YE Xian-guo

Abstract

The modal decomposition spectrum method for structure's energy response is advanced in this paper.Numerical examples show that the proposed method satisfies the elastic system well,but limitations exist in its application in elastic-plastic systems.Large discrepancy may happen for structure with plasticity deep and wide developed and it would be larger when plasticity goes deeper and wider,and the structure's maximum energy response would be highly overestimated or underestimated as the characteristics of the structure and earthquake input vary.
