Abstract:
The behavior of small size under-reinforced, partially prestressed, concrete bridge beams under repeated overloading was investigated. Results are reported regarding static and fatigue tests on fifty-two beams including three beam sizes and six different strand arrangements. The object was to study the influence of strand stresses, steel ratio, group strand action, bond, and non-pretensioned strand on fatigue life.
