Membrane structure parking shed Effective combination of design and construction
(1) Give design conditions such as load and boundary to control the design process
Design is a strong point of the design institute, so for complex membrane structures, the design conditions such as load values and boundary conditions should be determined by the design institute, especially the boundary conditions and wind loads. The boundary conditions membrane manufacturers basically assume that the boundary conditions are simply supported fixed points, without considering the structure nodes and the actual stress of the structure.
(2) Put forward design objectives according to building requirements; This problem is more important in engineering
In fact, the architectural appearance should be proposed by the architect, but the membrane structure has the problem of finding the shape, so the architect often requires the structural engineer to determine. But shape finding is not unique. Different internal force distribution will find a different building shape, and different shapes will directly affect the effect of the building. It is worth mentioning that different building shapes may directly affect the economy of the project. Because some shapes are difficult to realize and may require greater prestress, the problem is the difficulty of using more materials and construction technology. Therefore, the reasonable building shape should be determined by the cooperation of structural engineers and architects.
(3) Give control conditions such as output and displacement, and control design objectives
Although there are codes and regulations on cable structure and membrane structure in China, they are relatively incomplete. For some special problems, such as membrane displacement, cable displacement and other specific problems, designers need to consult relevant engineering data to determine. These details can only be carefully studied by yourself, and membrane structure companies usually do not do so much.
