Abstract:

The membrane structure is first discreted into the cable’net structure according to the method of stress equivalence.Next,for a cable-net structure,nodal equilibrium equations of free nodes are directly established,ac-cording to which formulas for the form--finding and loading analysis of the membrane structure are individually de-rived.Then,the isostress surface assumption and wrinkle problem of the membrane structure are discussed.A pro-gram for the form-finding and loading analysis of the membrane structure are finally developed.Some examples veri-fy the feasibility of the proposed methods.

Key words: membrane structure, form-finding, loading analysis, isostress surface, wrinkle
