| Abstract: | The basic equations for formfinding of airsupported membrane structures are derived from the nodal equilibrium condition of discrete membrane surface.On this basis,the solution methods for the two kinds of initial equilibrium membrane surfaces with equal stress density or equal stress are proposed.Calculation program is realized according to the suggested methods and two form finding examples are illustrated.The examples demonstrate that in this paper the theory and program are correct and the solution methods are simple and efficient for the formfinding of airsupported membranes. |
