Application of Pushover Analysis on Earthquake Response Predication of Complex Large-Span Steel Structures
Abstract eng: Pushover analysis has been widely used on earthquake response predication of building structures under severe earthquakes. It needs be studied whether it is applicable for complex large-span steel structures or not. In this paper, pushover analysis of two practical engineering projects, Beijing A380 hangar at Capital Airport and the National Stadium for 2008 Beijing Olympic Games, are introduced. The first mode lateral loading pattern for the hangar structure and twelve cases for the stadium steel structure are adopted to perform the pushover analysis respectively. The pushover analyses results are compared with nonlinear time history analyses results. It is concluded that pushover analysis is applicable for certain types of complex large-span steel structures, providing the total modal mass participation factor is larger than about 0.65.
