Reparation of Trusses in the Steel Plant Environment (Room 317)

In an competitive world, where the growing need to develop industrial production/productivity requires maximum performance, new technologies/equipment are required. Thus, is a need for reinforcement/retrofit of structural elements. After some years, a structure can present pathologies that can be caused by new loading, design/assembly/fabrication deficiency or even lack of maintenance (mainly). Therefore, when it is necessary to accommodate new loads, it is crucial that the proposals contemplate the new loadings and a good structural condition. This paper reports the field experience during the work of repowering trusses with almost twenty years of use, in an extremely aggressive environment.
