Resum
This paper presents a model developed in the frame of doctoral research of the first author, for the analysis of the tensional sectional response of a partially prestressed concrete bridge to fatigue action. It accounts for the non-linear constitutive relations in the materials within the section, and for the natural uncertainties inherent to the main variables involved in this problem. It also gives a statistical definition of the SN curves and of the variable "Miner Summation at Failure" for t...
