Study On Wind Load Characteristics Of Large-span Stadium

With the rapid development of the current construction industry,large-span structures are gradually recognized by most people.However,large-span structures are easily affected by wind loads due to their light weight and small damping.In the design of engineering projects,the value of wind load plays a vital role.Based on the practicability of computational fluid dynamics and numerical simulation,and the innovative design concept of designers,the large-span stadium structure has also become more and more diversified from the traditional simple model,and a lot of complex and irregular structures have emerged,which has brought corresponding difficulties to the value of wind load,leading to the current domestic and foreign wind load specifications to not meet the needs of designers,and the lack of similar buildings with reference value,It shows that it is more significant to study the wind pressure distribution on the surface of large-span stadium.Based on the wind tunnel model test data of a large-span stadium,this paper focuses on the basic wind pressure,which is the main parameter of wind resistance design,and analyzes the wind resistance of large-span roof structure comprehensively and systematically from the aspects of average wind pressure distribution characteristics,fluctuating wind pressure distribution characteristics,wind pressure spectrum characteristics,side aluminum panel hollow wind parameter values and wind resistance structure design measures.
