Fatigue Behavior of Pretensioned Concrete Girders
This report summarizes the fatigue testing of full scale precast pretensioned girders with unshored cast-in-place slabs. It includes an extensive literature review of prestressed concrete fatigue and of development of design specifications relating to fatigue of prestressed concrete. Detailed summaries are given of the fatigue and ultimate behavior of a series of full scale test specimens including static and dynamic loads, deflections, stresses, and crack measurements. The main variables included maximum nominal concrete tensile stress level; girder strand stressranges; cross sections (both Texas Type C and AASHTO Type II girders); strand patterns (both straight and draped); passive reinforcement; degree of precracking; presence of occasional overloading; and prestressing losses.
