This book was released on 2009 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: "This thesis presents the results of a pilot study to apply externally bonded Carbon Fiber Reinforced Polymer (CFRP) sheets to strengthen a simple span reinforced concrete solid slab bridge built in 1922. Strengthening with CFRP sheets was accomplished in three days without traffic interruption, and preparation consisted of only light sandblasting. Bridge G-270 is the only load-posted structure on a heavy truck route that serves a lead mining operation and the objective was to strengthen the bridge to allow removal of the load posting. The University of Missouri-Rolla conducted the pilot study for the Missouri Department of Transportation (MoDOT) under MoDOT Contract No. RI98-012. The laboratory testing included the static flexural test of two full-scale beams, designed as a unit strip from the existing bridge deck, and the fatigue bond test of coupon- type specimens. Two reinforced concrete beams, a control beam and a beam strengthened with externally bonded CFRP were tested under four point bending. Coupon-type specimens consisting of unreinforced concrete beams with a reversed T- shaped cross-section and with a CFRP sheet applied to the bottom were tested. The purpose was to investigate the behavior of bond between CFRP sheets and concrete under fatigue loading. The field load testing of the bridge, before and after strengthening, was performed by the University of Missouri-Columbia to verify the performance of the bridge after the application of externally bonded CFRP. Long-term field measurements also were conducted to monitor the durability and the strain condition of the strengthened system. Pennsylvania State University conducted the monitoring of durability by studying the electrochemical effects of the CFRP material on the degradation of the reinforcing steel. Fiber-optic strain sensors were applied to the FRP reinforcement and the concrete to allow for long-term monitoring of the integrity of the FRP reinforcement. This pilot study was a success. Laboratory and field tests indicate that CFRP sheets, externally applied to a bridge superstructure, strengthened the slab and will allow the removal of the load posting. Monitoring of the bridge will continue"--Abstract, leaf iii

This book was released on 2004 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This investigation studied the structural performance of FRP composite materials in bridge decks through in-place load tests and analytical studies. Two multi-panel bridge decks were studied: Saint Francis Street Bridge consisting of a deck built with four glass FRP (GFRP) honeycomb panels, whereas Waters Street Bridge consists of nine FRP-RC panels. The performance of the two bridges was monitored by load tests for over three to four years. The main objectives of this investigation were: to examine the deflection data in service that can be correlated to allowable deflections; to estimate if there is any stiffness degradation that can indicate distress in the deck; to compute the load fraction distribution between panels based on experimental data and attempt the load rating using the load test results"--Introduction, leaves 2-3.
