Optimization of lattice steel structures. A parametric approach based on statically determined structures

Abstract

Abstract Although several optimization methods have been developed in recent years, their application in real projects is still not widespread due to the complexity of implementation. This paper presents a simplified practical methodology for optimizing trussed steel structures with a focus on the feasibility of the structural solution. The proposed method is parameterized based on statically determined structures with topologies inspired by Michell trusses. In the examples evaluated, the reduction in self-weight reached 24.6% combined with a reduction in displacements of 29,3% in relation to conventional structures.
