RESEARCH ON NUMERICAL SIMULATION OF WIND-LOAD ON SUSPENDED RETICULATED SHELL UNDER TYPHOON

In order to study the distribution characteristics of wind load of suspended latticed shell structure under typhoon，the Fluent software and computational fluid dynamics( CFD) technology was applied in this research． the numerical simulation of distribution law of wind load on shell structure under different working conditions of typhoon was carried out based on SST k － turbulence model and Tianpus turbulent intensity in this paper． And the distribution law of wind load under different wind directions and elevations was analyzed． The comparison of numerical simulation result and shape coefficient according to Load Code for Design of Building Structures ( GB 500092012) shows that the average wind pressure coefficient in numerical simulation was larger than the value of wind load shape coefficient in the load code． The result has certain reference for typhoon-resistant design of large-span spatial structure for references．
