A large number of buildings with large-span or complex-shape have come to the fore in recent years. To these structures, wind load tends to be control load in the structural design. Shape coefficient of wind load which Chinese load code for the design of building structures can provide is extremely limited due to complex-shape of long-span space structures, therefore carrying our related study is of great practical significance. Yancheng Financial Center model is established in this paper based on ETABS software. The acquired date in the use of wind tunnel test is to simulate wind load which is on the structure and to analysis stress distribution of critical element in order to ensure safety and applicability of structures. This paper mainly covers wind tunnel test, equivalent static wind load, and wind-induced response, etc.
The isolation of large-span Steel Truss Roof structure is developed on the basis of base isolation. The isolation of large-span Steel Truss Roof structure is to limit the transmission of wind load effect to the substructure. Based on the engineering background, we mainly discuss using rubber bearing isolation structure wind load effects. This paper will explains and demonstrates the isolation mechanism of Large-span Steel Truss Structure,and than test and verify isolation effect by Calculating through the analysis of wind tunnel tests conducted on the Yancheng financial services center, which the steel truss roof isolation bearings for wind load effect isolation effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
