Abstract:

This paper presents newly established probabilistic models of ultimate shear and bending resistance of typical reinforced and prestressed concrete bridge section. The models have been developed using recently collected data regarding variability of mechanical properties of concrete, reinforcing and prestressing steel, and also variability of the section dimensions. The uncertainty of the mathematical models, used for the calculation of the sectional response, has as well been taken into account. The proposed models have been developed to be used in the load capacity evaluation of existing bridges by means of probabilistic methods. However, they can also be used for the calibration of the partial safety factor in the existing design or assessment codes.
