Load Effect of Sewage Tank Film Covering

Sewage pond membrane cover is a new type of sewage pond waste gas treatment structure. This structure fundamentally avoids the corrosion of the steel frame by the waste gas in the pond, improves the service life of the steel structure, and also improves the performance of the membrane cover structure Advantage. When the anti-hanging membrane structure generates large stress or deformation under load, the membrane structure should be adjusted back to the initial shape determination stage. Usually, the size and distribution of the initial pretension can be adjusted, the structure shape can be adjusted, or the number of reinforcing cables can be increased.

The anti-hanging membrane structure of the sewage pond has a small dead weight and is a wind-sensitive structure, which is prone to large deformation and vibration under the action of wind load. A certain amount of research work has been carried out on this issue at home and abroad, but due to the different forms of membrane structures, it is difficult to describe it with a unified wind carrier type coefficient and wind vibration coefficient. For buildings with complex shapes, large spans or important buildings, wind tunnel tests and wind vibration analysis must be carried out to determine the dynamic impact of wind loads. For the more commonly used framework-supported membrane structures and tensioned membrane structures, the reference values of the wind carrier type coefficient and wind-vibration coefficient are given on the basis of summarizing the existing domestic research results, which is convenient for engineering design and application.
