Repair of prestressed (post-tensioned) concrete beams after damage by fire

The following notes describe the repair carried out to the soffit and sides of precast prestressed beams damaged by fire. The method used involved full live loading of the construction to simulate the conditions of the original design as it concerned the state of stress in the concrete. The full loading condition also provided a satisfactory test of the composite construction and the combination of prestressed concrete and in-situ reinforced concrete acting together as a continuous structure.
