1. initial equilibrium analysis. That is, the membrane structure is determined. The initial shape produced by applying prestress is the premise of structural load analysis, and a reasonable shape can ensure a reasonable equilibrium stress system. The early shape-finding technology mainly used the physical model method, its classical method is soap bubble forming method and weaving shape-finding technology object model method today, the shape-finding method is based on some basic balance surface modeling computer analysis system. In this system, structural surfaces with fixed topological relationships are discretized into finite element meshes, but the coordinates of other nodes are approximations except at fixed points. Once any form of external load is applied, the unbalanced forces at the nodes can be determined. In this way, the unbalanced forces at these nodes must cause the finite element mesh to be disturbed, so that the node coordinates of the equilibrium shape can be solved, I .e. the initial equilibrium state.
2. structure design: that is, the edge support design of the membrane structure. It may be considered to use a built building or an edge support design structure as the edge support of the membrane structure. Or use the support form of the support rod and the cable. Separate column forms may also be employed.
3. load analysis load analysis using finite element analysis technology,: load analysis membrane analysis: a variety of loads on the initial equilibrium surface. The tension membrane structure is subjected to load analysis to check whether the membrane element stress, node position and other constraints are met. If it is not satisfied, the first and second steps are repeated until it is satisfied. Structural analysis: apply loads to the structure to determine whether the overall stability of the structure and the strength and stiffness of the components meet the design conditions. If it is not satisfied, the first and second steps are repeated until it is satisfied.
4. diaphragm clipping diaphragm clipping: stress release of diaphragm; 3. Expand all diaphragms into planar form and divide them into the following steps: 1. Divide the balanced membrane into several small diaphragms; 2. Considering the influence of membrane internal force. Dimensioning is given.
