Many people usually don't know the points of attention in membrane structure design. So what should be paid attention to in membrane structure design? Let's look down together.
1. The stability of the structure under wind load
Although the membrane structure has good adaptability to earthquakes, due to the complexity of wind load, it is impossible to fully simulate the situation of the structure under wind load, especially when the membrane structure is prone to self-excitation under wind load. Vibration leads to structural damage. Therefore, when conducting wind load analysis, a limit state design method based on probability theory should be adopted to ensure that the membrane structure can remain stable under complex and extreme weather.
2. The choice of membrane material must meet actual needs
When designing the membrane structure, we should fully consider the natural environment of the area where the building is located, the nature of use, the service life, the structural span, the fire protection requirements and other factors. And other aspects must meet the actual needs of the building.
3. Membrane structure design must consider the feasibility of construction
Membrane structure design should consider the feasibility of the construction process in the form-finding design, load analysis, and cutting design, and consider whether the site meets the required conditions for construction in stages, and then conduct an integrated design on this basis.
4. The strength of the membrane material should be greater than the extreme stress
PVC/PVDF membrane material has strong tensile strength but weak compressive capacity. When designing, it should be noted that the strength of the membrane surface should be greater than the extreme stress, and it should be considered whether the membrane material can not be damaged under long-term load.
5. The service life of the membrane material should be greater than or equal to the service life of the building
6. Convenience of replacement of membrane materials
When the membrane structure is designed, it should be considered whether the replacement is convenient when the membrane material is damaged or aging and needs to be replaced, and it must be ensured that the replacement of the membrane material will not affect the overall structure.
7. The stability of the support structure when the membrane material is damaged
When the membrane structure is designed, it should be considered that the support structure should maintain its own strength, rigidity and stability after the membrane material is damaged. When the membrane structure is designed, the aging of the membrane material should be considered to ensure the stability of the membrane material within the normal service life.
