Abstract

The optimal prestress reinforcement of civil engineering structures is analy- zed in this work. A modal analysis framework is assumed for the dynamic, aseismic design. The prestress action is modelled by means of induced tem- perature fields in the prestress cables. The optimal choise and the optimal placement of the tendons are treated by a ground (sub) structure technique. The proposed method is illustrated by means of numerical examples. 1 Introduction Reinforcement of structures with prestressing elements, which modify the stress distribution and permit a more beneficial use of the materials
