Resumo
The aim of this paper is the development of a probabilistic optimization
program for truss structures, by using a heuristic algorithm (Branch and Bound) and
by using a technique to determine the failure probability of a structure (Monte Carlo).
For structural volume minimization, the project variables are the areas and the
inertia of the cross-sections. The constrains are the maximum tension in each bar,
buckling in compressed bars and specific nodal displacements. Examples using
deterministic optimization are used in order to evaluate their compatibility in terms
of reliability. The obtained results show that the deterministic optimal solutions are
not compatible with this requisite, while non-deterministic solutions have a higher
material volume, in order to raise the system reliability.
