Study On The Design Of Umbrella Membrane Canopy Roof Of Large Stadium

Along with the development of the times,People’s material and spiritual life levels are being improved constantly,and a variety of large stadiums, cultural facilities, commercial facilities, transportation facilities and other public facilities have been completed for Enriching our daily life. As a suitable structure for these kinds of public facilities, membrane structure has been paid more and more attention by designers. It is because of the fact that embrane structure usually appears in public places with intensive personnel, more attention should be paid by designers to the safety level of the structure. Due to the variety of construction forms, different load effect under different construction forms and mechanics particularity, the development of membrane structure is relatively backward in China, which becames the main factors of restricting the development of the industry. Thus the research on membrane structure is very important for its development.The main work of this paper focuses on the design of umbrella membrane canopy roof of large stadium. The research begins with the analysis of a single umbrella membrane structure, then finds the influence factors and the load effect of it, then does some systematic analysis and research on the key problems of the overall structure(include load effect analysis, Scheme optimization, etc).
