Abstract
Load Path Network Method (LPNM) [1] is an equilibrium-based method for the design of three-dimensional structures based on the lower bound theorem of the theory of plasticity. The goal of this method is to stimulate the exploration of possible three-dimensional flows of internal forces in equilibrium in a structure in order to help the integration of structural concerns in the design process of a building project. This paper shows the application of LPNM for the design of prestressed shell structures. The goal of this application is to allow the designer to find the right layout of prestressing cables and the necessary amount of prestressing force in such cables in order to keep the mass of concrete of a given shell structure only or mainly under compressive forces.
