Abstract
The main difference between the design of a tension structure and the design of a regular structure (as buildings, bridges,...) is that the shape of a tension structure is usually not known at the beginning of the design process and many different shapes are possible for given boundary conditions. Shape-finding or form-finding is the first step in the design of a tension structure. The stress distribution and the shape of a tension structure are related, this is a particularity of this kind of structures. Several form-finding methods for tension structures are already available in the technical literature, all of them posses certain limitations and drawbacks and no single method is optimal for all problems. The engineer may select the proper combination of methods best suited to the designer's needs. In this paper we propose a combined straight method to achieve satisfactory equilibrium configurations for fabric tension structures, making use of stress control over surface elements to optimize the final shape of the tension structure. The force density method (FDM) implemented with topological mapping (TM), a method recently developed by the authors (FDM-TM), is used as a search engine for the preliminary design. A detailed example is presented to illustrate this extended application of topological mapping.
