Abstract


In the sphere of decision-making for resistant structures project, the mere mechanical analysis of a model does not suggest the possible material reduction resulting from changes in the structural form. In order to quantify these improvements it is essential to be able to measure the structural consumption in the early stages of design. So in this paper we present and compare two of the currently most developed theories that connect geometry with material consumption of the structure. To demonstrate the versatility of these concepts, they will be applied to a type of structure with both residual stresses and large deformations: coupled structures. This particular case of structures is generated by pre-bent elements, where the components are associated by pairs to form tied-archs groups.
