In rainy days, there will be stagnant water in many places. If the problem of stagnant water is not dealt with, it will become more and more severe, with serious consequences. For membrane structures, how can we prevent and solve the problem of water accumulation in membrane structures in rainy days? Let's discuss it together today.
How to prevent and solve the problem of water accumulation in rainy days?
The first problem to be solved is to avoid local flat areas when looking for patterns. This can be prevented by increasing the arc of the arc around the membrane structure and increasing the slope of the membrane.
How to solve the overall stability of membrane structure under wind load?
First, find out the large deformation parts under wind load, and the specific value of the deformation. By increasing the pretension of the cable and recalculating the deformation value, if it is not satisfied, a new steel cable needs to be added to control the deformation of the local membrane. In this case, the amount of steel cable will increase a lot.
How to avoid film surface damage?
Because the membrane material itself is very light, the wind load becomes the controlled external load of the membrane structure. How to properly deal with the effects of pre-tensioning on the membrane structure modeling and the effect of wind load on the stress and deformation of the membrane material to avoid excessive local stress concentration and local excessive deformation under the action of high wind are the current few membrane structure projects in China that have been destroyed. Key issues overlooked by sexual destruction.
In order to avoid this problem, it is necessary to thoroughly understand the analysis theory of membrane structure. The external loads to be considered are self-weight, wind load, snow load, and should be combined with the prestress applied to conduct a reasonable analysis. It is especially important to pay attention to analyzing The overall stability of the membrane structure under load is strictly controlled, and local excessive deformation under wind load is strictly controlled.
