Resum
The paper presents a model for the analysis of the response of prestressed concrete bridges to fatigue. Due to fretting effects, fatigue is mostly important in concrete bridges with post-tensioned tendons where cracking is present due to unexpected external loads or design assumptions (partial prestressing). The model considers the non-linear sectional response due to the material constitutive laws and cracking. Cracking may be due to service loads, thermal gradient and differential settlements ...
