Original Abstract

The paper describes a comprehensive computational procedure to determine global structural resistance of the existing bridge made of I-73 precast post-tensioned concrete girders using the advanced methods of statistical assessment in combination with nonlinear finite element method analysis. A fully probabilistic approach for the determination of the structural design resistance 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. Load-bearing capacity is determined for the ultimate as well as selected serviceability limit states. The paper shows that applicability of nonlinear modelling considering uncertainties is feasible and can be applied in a routine way. Shortcomings and advantages of all utilized design/assessment methods are discussed.
