Análise de tabuleiros de ponte: comparação entre os efeitos causados por um veículo real e o veículo normativo

Abstract

By definition, bridges are structures used to overcome natural obstacles and because of its socioeconomic importance and need to associate safety and cost. It’s of great relevance to obtain and compare the efforts of normative vehicle against a real vehicle. For this purpose, two calculation models were used: the standard train of the norm NBR 7188/2013 and a real vehicle. With the help of SAP2000 V12 software, via finite element methods, the analyzes were performed. The results demonstrated the superiority of the normative vehicle as compare to the actual vehicle, but it is important to emphasize the need to distribute the load in determining the efforts and the spacing between the axes of the real vehicle, so that it does no offer significant structural risks to the structure. It is worth noting that the regulatory vehicle is at the limit of its safety.
