Shape Finding Analysis of Membrane Structures Based on Real Material Property
In order to obtain a real shape of membrane structure, a new shape finding method was developed based on real material property. The curved shape is first obtained by raising the control points above the projection plane. The convergence was improved using pseudo material properties to get a preliminary shape, and then the real properties to get the final shape. A large number of examples were analyzed to verify the validity and practicality of this method. The results showed that the final curved surface after the second shape finding process was always quite similar to the first one. Moreover the curved surface obtained after the second shape finding process is accurate and will be realized in real.
