A common problem in the optimization of structures is the handling ofuncertainties in the parameters. If the parameters appear in the constraints,the uncertainties can lead to an infinite number of constraints. Usually theconstraints have to be approximated by finite expressions to generate acomputable problem. Here, using the example of the topology optimization of atruss, a method is proposed to deal with such uncertainties by using robustoptimization techniques, leading to an approach without the necessity of anyapproximation. With adequately chosen load cases, the final expression isequivalent to the multiple load case. Simple numerical examples of typicalproblems illustrate the application of the method.
