Resumo: | ||||||||
Mechanical parameters used in the analysis and design of
structures, such as the elasticity modulus and the yielding
stress for the material as well as the loads, are in fact,
random rather than deterministic variables as they are
usually considered. Consequently, the structural response,
such as displacements and stresses, are also random
variables, and in this way, there are uncertainties while
determining these variables. In this work the uncertainties
related to the mechanical parameters for the material and,
as consequence, the uncertainties corresponding to
structural response will be taken into account in the
optimum design of framed structures, such as trusses and
frames. For the determination of the structural response
considering uncertainties, the linear statistical method
will be applied. The sensitivity analyses will be performed
by the direct analytical method and the interior point
algorithm will be used as optimization algorithm.
