A common problem in the optimization of structures is the handling of
uncertainties in the parameters. If the parameters appear in the constraints,
the uncertainties can lead to an infinite number of constraints. Usually the
constraints have to be approximated by finite expressions to generate a
computable problem. Here, using the example of the topology optimization of a
truss, a method is
... [Show full abstract] proposed to deal with such uncertainties by using robust
optimization techniques, leading to an approach without the necessity of any
approximation. With adequately chosen load cases, the final expression is
equivalent to the multiple load case. Simple numerical examples of typical
problems illustrate the application of the method.
