Resum
This paper presents newly established probabilistic models of ultimate shear and bending resistance of typical reinforced concrete (RC) and prestressed concrete (PC) bridge cross-sections. These new models were developed using advanced analysis methods and the most recent data regarding variability in mechanical properties of material and cross-section geometry. The models also take into account the uncertainty related to the inaccuracy of the analysis method used to evaluate member resistance. ...
