Vergleich der rechnerischen Querkrafttragfähigkeit von Bestandsbrücken nach Eurocode 2 und fib Model Code 2010

Comparison of the calculative shear resistance of existing bridges according to Eurocode 2 and fib Model Code 2010

Due to the constantly increasing traffic loads and the revised design approaches it becomes necessary to reassess the expected service life of existing bridges. In many cases the calculative shear resistance turns out to be particularly problematic. In the course of the revision of the Austrian Assessment Technical Regulation ONR 24008 "Evaluation of load capacity of existing railway and highway bridges" comparative calculations according to the shear carrying capacity of existing bridges conforming to Eurocode 2 and fib Model Code 2010 were carried out. The present paper summarizes the main results of the comparison between the fib Model Code 2010 and Eurocode 2 and explains characteristics of the calculations of the shear resistance according to fib Model Code 2010.
