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: In the last two decades, the rapid deterioration of bridge structures has become a serious technical and economical problem in many countries, including highly developed ones. Therefore, bridge rehabilitation has also become a very essential factor (sometimes even a decisive one) in contemporary bridge engineering. The book covers in synthetic form nearly all the most important problems concerning bridge rehabilitation, such as bridge superstructure and substructure, the typical damage observed in bridges as well as the assessment and evaluation techniques of their technical condition. The book is intended mainly for postgraduate university students. Therefore, all the problems are mostly presented in their physical, chemical and technical as well as economical aspects. The relevant requirements are treated as objective ones, i.e. irrespective of the rules, standards, regulations or guidelines particular to any country. This approach to the subject gives the book a more general character and therefore makes it a useful text for most civil engineering courses.
Book Synopsis Composite Action in Prestressed NU I-girder Bridge Deck Systems Constructed with Bond Breakers to Facilitate Deck Removal by : Chaohui Li

This book was released on 2017 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are reported from tests of small-scale push-off and large-scale composite NU I-girder specimens conducted to establish an interface connection detail that (1) Facilitates in-situ removal of the bridge deck without damaging prestressed girders, and (2) Maintains composite action between the prestressed girder and reinforced concrete deck throughout the service-life of the structure. Sixteen small-scale push-off tests were conducted to investigate the influence of surface preparation, bond breakers (epoxy and roofing felt), and interface reinforcement properties (yield strength, reinforcement amount, and means of anchorage) on horizontal shear transfer between precast and cast-in-place concrete surfaces. Based on the push-off test results, a connection detail was proposed that consists of roughening the top flange of the girder directly over the girder web and debonding the remainder of the interface using No. 30 ASTM D4869/D4869M-16a Type I organic roofing felt. Three full-scale composite NU35 girders, designed and fabricated using the proposed connection detail and two control connection details, were then subjected to a series of tests. First, decks were cast and then removed to quantify the extent to which the proposed connection detail reduced the effort to remove the deck and to document the types and extent of damage caused to the girders by the process. After replacing the decks, the composite girders were subjected to 2×10 (6) cycles of simulated traffic load and then loaded monotonically to failure. The proposed connection (partially roughened/partially debonded with a roofing felt bond breaker) is a viable option for use in practice; its use led to a 2/3 reduction in the effort required to remove the deck over the girder and protected the girder from all non-saw-related damage while also effectively sustaining composite action through 2×10 (6) cycles of simulated traffic load after deck replacement. The proposed connection can be conservatively designed by neglecting the debonded area when calculating interface shear strength. Other test results showed that surface preparation has a large influence on the stiffness, strength at cracking, and peak strength of a horizontal shear connection; each was greatest for specimens with a fully roughened surface followed by the partially roughened surface, troweled surface, and debonded surface. Increasing the amount of interface shear reinforcement increases the initial stiffness, shear strength at cracking, and peak and post-peak strength, and does so more effectively than a similar increase in reinforcement yield strength. Casting and removal of bridge decks without bond breakers does alter the top surface of bridge girders, but the surface can be returned to a qualitatively roughened surface with reasonable effort and care. Despite the changes to the top girder surface caused by deck removal, composite action was developed across the interface and remained stable through 2×10 (6) cycles of loading.
