Form Finding/Pattern Generation of Membrane Structures Using a Neural-Genetic Procedure
Membranes are 2D flexible continua which have always been under consideration for structures requiring large spans and high strength to weight ratio and elegant architecture. Because these structures undergo large deformation and cannot be made as a single piece, their design and analysis for practical purposes is very complicated. Finding the cutting pieces to be sutured and put under load to generate the final form of the structure by itself is a very important, interesting, and yet cumbersome task. Most researches on the market find these cutouts by different methods for a given final form of structure in order to obtain a less stressed fabricated final form. In this study, a parametric axisymmetric 3D surface with unknown parameters is considered and using a Neural-Genetic algorithm, both the final form and the 2D cut outs are simultaneously obtained for an optimum final configuration from a stress point of view. Some examples are presented.
