Sewage ponds are covered with anti-hanging membrane structure, and the load capacity usually refers to wind load and snow load. The deformation of the membrane structure is relatively large under the load, so the accurate calculation of the deformation and stress distribution of the structure must be carried out using geometric nonlinear methods. According to the most unfavorable situation of the internal force distribution in the structural members such as cables, membranes, beams, and rods calculated under different working conditions, the types and sizes of materials such as cables and membranes are selected, and the detailed node practices and structural measures are determined.
Secondly, the main purpose of load analysis is to test and determine the initial prestress in cables and membranes. In general, the form finding analysis first assumes a prestress value and distribution based on experience, and then judges its rationality through load analysis, namely The size and distribution of stress should be such that it must meet the use requirements under the most unfavorable working conditions, and at the same time meet the needs of overall and local displacement and drainage function.
The difference of the membrane cover of the sewage pond is that it adopts the principle of membrane material hanging, which not only can extend the service life of the steel structure, but also has a good collection effect for the exhaust gas, and the membrane is loaded with a strong load. Therefore, it is obtained by people in the industry. Favored, the usage rate continues to increase.
