Analysis of Wind Loads Acting on Large Span Double-Arched Roof Structure with Opening Ends

Abstract

Due to the complexity of large span double-arched roof structure, Chinese load codes are not enough for the design. Other method should be used to ascertain the wind load on the roof structure. Computational fluid dynamic (CFD) is a newly developed research method for wind loads. The distribution of wind pressure and wind environment on the roofs of large span double-arched structure were computed based on ANSYS-CFX12 software platform with Reynolds stress model(RSM). By the simulation, the unfavorable wind shape coefficient is obtained which help the designer to enhance the key component for the safety of the serviceability performance.
