First, the membrane structure adopts the limit state design method based on the probability theory, and calculates with the design expression of the sub-coefficient.

Second, the membrane structure should be based on the nature and grade of the building, the use of life, the use of functions, structure span, fire protection requirements, regional natural conditions and the durability of the membrane material requirements for the selection of membrane materials.

Three,the design of the membrane structure shall be carried out according to the load, the supporting conditions, the manufacturing process, the construction conditions and other special conditions.

Four,the design contents of membrane structure include shape design, load analysis, cutting design, accessory design and support structure design.

Five, the shape of the membrane structure design, load analysis, cutting design, should be considered in the construction process based on the integration of design.

Six, membrane material can only withstand tensile force, can not withstand pressure and bending moment.

Seven,the maximum principal stress of the membrane surface should be less than the strength design value of the membrane, and under the long-term load, the minimum principal stress should be greater than or equal to the stress value of maintaining its initial equilibrium shape.

Eight,when the membrane structure is integrated, the relaxation, creep and aging of the membrane material should be considered.

Nine, the membrane structure design, should consider the use of the stage membrane material replacement to the overall structure of the effect.

Ten, the membrane structure design should consider the membrane material destruction, the supporting structure should still maintain its own strength, stiffness and stability.
