Abstract

In the paper,the issues in wind-resistant design of Fangchenggang Culture Art Center,which has a large span roof with complex bionic shape,were studied in different structural design phases using three research methods,including CFD simulation,rigid model pressure measurement wind tunnel test and dynamic wind-induced vibration analysis.Through the analysis of the wind-induced loads on this large span roof,equivalent static wind loading on the roof surface was given for the main roof structural design.In practice,it is shown that this could be a good approach to solve some common problems in the wind-resistant design for complex large-span buildings.This study will provide a good reference for wind load estimation of the same type of buildings.
