Original Abstract

This paper compares several methods for assessing the design resistance of an existing reinforced concrete bridge structure. The determination of the load-bearing capacity of the structure is carried out by means of probabilistic nonlinear analysis using finite element method. Load-bearing capacity is determined for the ultimate as well as serviceability limit states. A fully probabilistic approach is compared to selected code-recommended semi-probabilistic methods, such as the ECoV method according to fib Model Code 2010, the method according to EN 1992-2 or the partial safety factor method. The results are compared and discussed with respect to accuracy and required computational time, which is a critical issue when performing a global nonlinear analysis of a complex structure.

Keywords

Reinforced concrete bridge, nonlinear analysis, probabilistic analysis, ECoV method, EN 1992-2 method.
