Testing and assessment of FRP strengthened concrete T-beam bridges in Pennsylvania

t is increasingly becoming of great concern that the transportation infrastructure is in poor condition and in need of rehabilitation. Reinforced concrete (RC) structures such as bridges are a prime example for displaying rehabilitation needs. Harsh environmental conditions and age, along with the use of deicing salts in the winter seasons, greatly increase deterioration rates. Addressing bridge conditions in an effective manner and ensuring the safety of the public is a challenge for engineers and owners.;The Pennsylvania Department of Transportation - District 3 (PennDOT-D3) initiated a program to address the condition of their concrete T-Beam bridges. 128 concrete T-Beam bridges constructed between 1920 and 1960 are included in the district's bridge inventory. Many of these bridges have become structurally deficient or obsolete due to aging and deterioration. PennDOT-D3 paired with West Virginia University researchers to develop a program that would use FRP rehabilitation technology to repair and strengthen its large number of concrete T-Beam bridges.;The work presented in this thesis focuses on the third phase of a three-phase project concerning the rehabilitation of bridge...
