Summary:This paper presents the optimization of steel penstock, designed to be built in a bored tunnel. The optimization was performed by the non-linear programming (NLP) approach. For this purpose, the NLP optimization model was developed. The model comprises the mass objective function, which is subjected to design and dimensioning constraints. The dimensioning constraints were defined according to C.E.C.T. recommendations. The penstock was designed without stiffener rings and without collaboration of the surrounding rock. Numerical example of the penstock optimization, planned to be made for the hydropower plant Kozjak in Slovenia, demonstrates the efficiency of the introduced optimization approach.
