Abstract
(type = abstract)
Aging infrastructures provide challenges in the areas of estimating the capacity of partially deteriorated structural members and their Rehabilitation to restore their load carrying capacity. Results presented in this dissertation deals with assessing a deteriorated prestressed girder of a bridge and a procedure to strengthen the weakened beam using Fiber Reinforced Polymer (FRP) composites. The condition of the prestressed box beam was assessed using load tests. The 46ft span beam was part of a support system containing of 21 box girders. The test-load truck was positioned to produce maximum possible moment on the deteriorated girder. All the box girders were instrumented to measure maximum tensile strain at the bottom surface of the beam. The strains at various girders were used to determine the fraction of road carried by the deteriorated girder. Stresses and strains were computed analytically for the test load and there is a good correlation between measured and computed values. The second aspect of the dissertation was to formulate a procedure to strengthen the beam using FRP composites. A fraction of the pre-tensioned wire were corroded and exposed due to environmental degradation. Carbon Fiber FRP composition repair scheme iii was designed assuming zero contribution from the damaged prestressing wires and assuming complete prestress loss. In the first scenario, amount of FRP needed to replace both prestressing force and reinforcement capacity of the damaged wire. In the second scenario, the damaged prestresing wires were assumed to act as non-prestressed reinforcement. The results show that load testing provides an excellent tool for assessing damaged beams and FRP system can be effectively used to restore the capacity of damaged beams. Commercially available FRP systems were used for obtaining the necessary parameters for design.
