Distributed Fiber Optic Sensing for a Full-scale PC Girder Strengthened with Prestressed PBO Sheets
Fiber Reinforcement Polymer(FRP) has been widely accepted as an innovative material for renovation and strengthening of existing infrastructures. Among the FRP materials, the Poly-p-phenylene benzobisoxazole (PBO) fiber sheets attracted great attention in recent years because of the high strength, high Young modulus and high energy absorption capability. In this study, a PBO Prestressing Upgrad...
متن کاملExperimental Study and Modeling of Reinforced Concrete Beams Strengthened by Post-Tensioned External Reinforcing Bars
The utilization of unbounded external reinforcing bars is one of the strengthening methods used after loading stage and before failure. The method has been used in different forms to strengthen members of reinforced concrete structures. To investigate the effect of utilization of post-tensioned reinforcing bars in this method of strengthening, a number of reinforced concrete beams was tested. S...
متن کاملLamb Wave Behavior in Bridge Girder Geometries
Lamb waves in plates and in cylindrical pipes have been the subject of extensive study, largely because they propagate great distances with little attenuation, and can therefore be used to detect flaws. In this paper we report finite element simulations and experimental studies of Lamb waves in steel bridge girder geometries. In our studies the Lamb waves are generated by PZT wafer-type transdu...

متن کاملFlexural Capacity of Rc Beams Strengthened with Srp and Srg
The use of externally bonded Steel-Reinforced Polymer (SRP) and Steel Reinforced Grout (SRG) composites is a promising new technology for increasing the flexural and shear capacities of reinforced concrete (RC) members. The reinforcement system in these composites is a sheet made up of unidirectional cords consisting of tightly wound ultra high strength steel wires. The reinforcement can be mol...
