Steel Structure, Prestressing, Prestressed steel beams


The use of prestressed as a solution for steel structures has been proposed since the 1950s and, despite several published studies, is not yet widespread in the professional environment. Its application is made externally to the structure and, among its applications, it is recommended for rehabilitation and reinforcement. Its executive method is relatively simplified, since little changes from the executive procedures of passive steel structures and prestressed concrete. This work aims to analyze the behavior of a rehabilitated steel beam when submitted to the stages of prestressed. For this, tendons will be applied, causing bending also in the direction of less inertia of the structural element. According to the proposed model, it can be observed that the efforts present in the executive stage do not exceed the supporting capacity of the element. However, certain loading phases can cause instability if they are not checked correctly.
