• All the structural problems have an associated variability or uncertainty. In the design of structures there are parameters such as the dimensions of the structure, the mechanical characteristics of the materials or the loads that can have variations with respect to the design value. The goal of the robust design optimization is to obtain the design that is optimum and is less sensitive to variations of these uncertain initial parameters. The main limitation of the robust design optimization is the high computational cost required due to the high number of optimizations that must be made to assess the sensitivity of the objective response of the problem. For this reason, kriging model is applied to carry out the optimization process more efficiently. In this work, it is going to apply the robust design optimization on a continuous pedestrian bridge of prestressed concrete and box section.
