Minimization of the expected compliance as an alternative
approach to multiload truss optimization
Felipe Alvarez and Miguel Carrasco
Key words Topology optimization, structural mechan-
ics, multiload compliance minimization, stochastic load-
ing, expected compliance.
Abstract We show that a problem of finding the truss of
minimimum expected compliance under stochastic load-
ing conditions is equivalent to the dual of a special con-
vex minimax problem, and therefore may be efficiently
solved. This equivalence makes it possible to provide clas-
sic multiload compliance minimization problems with in-
terpretations in a probabilistic setting. In fact, we prove
that minimizing the expected compliance amounts to
solving a multiload like problem associated with a par-
ticular finite set of loading scenarios, which depend on
the mean and the variance of the perturbations.
