The collapse of Real Class building
Abstract This paper describes the scene of the Real Class building collapse, a residential building with reinforced concrete structural system and located in the urban area of the city of Belem / PA, occurred in 2011. The unconformities found in the building are displayed using data extracted from reports and verification of structural and architectural designs. The data was compared with the Brazilian code for reinforced concrete structures, NBR 6118 (2007), valid at the time of the accident. The security of the building was evaluated through a computer model with linear analysis with the software used by the designer. The conditions of the structural system designed and as built was evaluated with parameters of global stability and load capacities of columns and foundations. The results showed that the structure of the building was subject to large displacements and the sections of columns were unable to resist the stresses produced by regional wind actions.
