3.1 Prestressed concrete bridges
3.1.1 Defects in bending strength
In the past, many bridges suffered more or less serious damage as a result of an obvious lack of flexural strength. The most common causes of this inadequacy were: the "neglect" of thermal actions (thermal gradients), ignorance of the effects of stress redistribution through hindered deformation, improperly called creep stress redistribution in bridges built in phases, and an "optimistic" assessment of the prestressing force or of the effects of support...
