Resumo

Uncertainties are inherent in any structural system. Traditional design optimization techniques consider uncertainties implicitly by partial safe factors. However, Reliability-Based Design Optimization (RBDO) methods account for uncertainties explicitly. These methods find an optimum design that verifies several reliability constraints. The objective here is to obtain an economic and safe design. This paper describes several RBDO methods and the functions programmed to implements these methods. These functions form a package added to the well known Structural Reliability Toolbox Finite Element Reliability Using Matlab (FERUM). A structural example has been solved with the functions implemented: a transmission tower truss. © 2012 Springer-Verlag.
