Otimização geométrica de treliças planas utilizadas em coberturas metálicas

Abstract

In the conception of structural projects, modern professionals seek to reduce cost by minimizing material consumption without compromising efficiency of the system. This work aims at implementing a geometric optimization program to identify the optimum solution of an aluminum truss with the objective of minimizing its weight. It also intends to stress the importance of projecting more rational and sustainable systems, with a good benefit-cost ratio. Results of the study showed the optimization potential regarding the considerable weight reduction obtained. Additional assessments were made to verify the influence of areas, and the elimination of restrictions in the final geometry of the problem.
