Description
Summary:(2016), it was calculated the capacity resistant to the bending moment of the composite section and the limit distributed load for dimensioning in the Service Limit State. In the analysis, comparing the values of capacity resistant to the mean bending moment of NBR 8800 (2008) with AASHTO (2017), the first presents values 17.07% higher. [...]NBR 8800 (2008) and EN 1994-2-2 (2005) allow shipments distributed to upper limits, on average, 14.51% and 13.18%, respectively, to those made possible by AASHTO (2017). [...]as the span of bridges and viaducts increases, the greater the overall variation in the resistance of the composite section. [...]the discrepancy between the normative recommendations has a significant influence on the design process, and it is important to carry out studies in this area in order to standardize the procedures to determine the effective width.
