Influence Study of Substructure upon Dynamic Responses of Reticulated Shells under Severe Earthquakes
摘要
Abstract
This paper establishes the coupling system model of reticulated shell with the substructure,the full-range dynamic response analysis method is applied to investigate the failure characteristics of single-layer steel reticulated domes with substructures subjected to severe earthquaks. The influence of substructures on the failure mode and the ultimate load of reticulated domes subjected to severe earthquakes are examined; this paper puts forward a simplified analysis method for the coupling system and discusses the influence of the nonlinear material of substructure on the failure behavior of reticulated shells; the influence of the nonlinearity of substructure on dynamic responses are discussed. It is shown that the nonlinearity of substructure obviously changes the failure characteristics of the reticulated dome.关键词
