"This dissertation consists of five papers, which presents the results of research on the application of FRP composites on the strengthening steel bridge structures. In particular, the work focuses on both rehabilitation of steel bridge girders (flexural members), and steel bridge columns (compression members) with FRP composite materials. The first paper focuses on the flexural steel member strengthening. Based on the experimental results, it is clear that an increase in stiffness and ultimate load capacity of corroded steel members can be achieved from the application of CFRP laminates to the tension flange of corroded steel members. Peel off of FRP laminates was the observed failure mode of the retrofitted beams. The second through fifth papers investigate the feasibility of retrofitting of compression loaded steel members using FRP composite pipes filled with expansive light-weight concrete. First, a high-expansion light-weight concrete was investigated. Second, the local bond-slip relationship between steel and this type of concrete was developed. Finally, a FRP retrofit method was proposed for corroded steel bridge columns, and deficient steel columns were strengthened using this retrofit technology. Test results indicated that a restoration of ultimate load capacity of a deficient steel column with the proposed FRP retrofit technology is attainable. Also design guidelines were developed for the retrofit of stocky and slender columns"--Abstract, leaf iv.

While traditional retrofitting methods for steel bridge girders could be time consuming and uneconomical, an alternative repair method is suggested using Carbon Fiber Reinforced Polymers (CFRP) laminate strips, providing engineers with a competitive solution that will increase the life-cycle of repaired bridges. This study investigated its feasibility as an option to strengthen and rehabilitate steel bridges. The main advantages of using CFRP laminates are their light weight and durability, which results in ease of handling and maintenance. The research conducted experimental and analytical work to evaluate the effectiveness of strengthening steel beams by the use of novel CFRP laminate strips configurations. The research involved the testing of five experimental composite beams, in addition to the development of approximately 100 finite element models. The results showed a significant gain in the beam's elastic and ultimate capacities. The conclusion is that there are specific sensitive parameters controlling the effectiveness of the CFRP laminate rehabilitation technique. An adequate AASHTO design of the rehabilitation method, which takes into consideration the effective parameters, would result in an effective bridge structure.

The deterioration of steel in aging reinforced concrete bridges is a continual problem which could benefit from improved rehabilitation techniques that take advantage of enhanced and more durable materials such as fiber reinforced polymer (FRP) composites. Appropriately designed hybrid material systems benefit from the performance and durability advantages of FRP materials yet remain more cost effective than comparable all-composite systems. Development of rapid rehabilitation systems for the decks of concrete box girder bridges, which are increasingly common throughout the United States, is presented. One goal of this research is to assess and validate the use of FRP composite panels for use as both stay-in-place formwork and as the bottom longitudinal and transverse reinforcement in the deck of concrete box girder bridges. Performance assessments for full-scale two-cell box girder bridge specimens through monotonic and extensive cyclic loading provided validation for the FRP panel system bridge deck as a viable rehabilitation solution for box girder bridge decks. The FRP panel system performed comparably to a conventionally reinforced concrete bridge deck in terms of serviceability, deflection profiles, and system level structural interaction and performed superior to the RC bridge deck in terms of residual deflections, and structural response under cyclic loading. Assessment of a damaged FRP panel bridge deck system, which was repaired using a resin injection technique, showed superior performance for the repaired system in terms of integrity of the FRP panel interface and cyclic response. Rapid rehabilitation techniques for strengthening reinforced concrete box girder bridge deck overhangs using near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) were also evaluated. Analytical predictions of load carrying capacity and deflections provided correlation with experimental results, and the developed analysis methods provide an effective design tool for future research. Results from the laboratory testing of a bridge deck overhang strengthened with FRP showed significant increases in load carrying capacity as well as deformation capacity as compared to the as-built specimen without FRP. This research provides enhanced understanding of hybrid structures and indicates significant potential for rehabilitation applications to concrete box girder bridges.
