This book was released on 2009 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the experimental investigation of two joint details for use in precast bridge deck systems. U-bar and headed bar joint details were developed for use in accelerated construction applications. Both details, in practice, would consist of staggered protruding reinforcement that would allow for the anchorage of the precast deck component into the joint. Six specimens containing the joint details were constructed and tested. Three specimens were tested in flexure to simulate the forces that would be experienced in a longitudinal deck joint, and three specimens were tested in tension to simulate the forces that would be experienced in a transverse joint over an interior pier. The three specimens of each test type consisted of one specimen containing the headed bar detail and two specimens containing the u-bar detail. The u-bar detail was tested utilizing two materials, welded wire reinforcement and stainless steel reinforcement. Welded wire reinforcement and stainless steel reinforcement were used for the u-bar detail due to their ductility which was needed to fabricate the tight bend (3d[subscript b]) used in the detail. The tight bend was used to minimize the thickness of the deck. The main objective of the testing was to determine if the joint details could create a precast deck system that could emulate the monolithic behavior of the predominately used cast-in-place deck systems. To achieve monolithic behavior in a precast deck system the joints must be able to transfer shear and tension forces as well as moments. The second objective of this investigation was to determine the best performing detail for further investigation. The additional investigation of the best performing joint detail would then be the first step in creating standard design guidelines and details to ease the future implementation of joints for precast bridge deck systems.

This book was released on 2010 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Interstate Highway System plays a vital role in our economic development by providing a continuous corridor for transporting goods and services. Currently, there is a need for repair and expansion of the existing highways, which include all bridges along its path. Because of the high demand for the highway system, repair and expansion must occur rapidly and efficiently. In recent years, precast bridge deck systems have become an efficient way to reduce construction time during repair. This thesis presents the experimental research of the behavior of the U-Bar joint detail used in precast bridge deck systems. This detail consists of staggered reinforcement extending beyond the precast deck portion into the joint. Six specimens utilizing the U-Bar detail were constructed and tested. Three specimens were tested in flexure to simulate the forces applied in a longitudinal deck joint, while three specimens were tested in pure tension to simulate the forces experienced in a transverse deck joint located over an interior pier. A tight 180° bend at 3d[subscript b] was desired in order to minimize the thickness of the deck. To achieve this tight bend, deformed wire reinforcement was chosen for the U-Bar detail due to the favorable material properties of deformed wire reinforcement. The purpose of the testing was to determine if the joint details could generate a precast deck system that could emulate the monolithic cast-in-place deck systems already in use. For monolithic behavior in a precast deck system, the joints must be able transfer shear, tension and moments. In this research, the joint overlap length was the most dominant variable, and should not be less than 152.4 mm (6"). The precast bridge deck joint should consist of high strength concrete with f'[subscript c] of at least 68.9 MPa (10 ksi). The longitudinal reinforcement spacing should be no greater than 152.4 mm (6").

This book was released on 2002 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: A literature review concerning the objectives of the project was completed. A significant number of published papers, reports, etc., were examined to determine the effectiveness of full depth precast panels for bridge deck replacement. A detailed description of the experimental methodology was developed which includes design and fabrication of the panels and assembly of the bridge. The design and construction process was carried out in cooperation with the project Technical Review Panel. The major components of the bridge deck system were investigated. This includes the transverse joints and the different materials within the joint as well as composite action. The materials investigated within the joint were polymer concrete, non-shrink grout, and set-45 for the transverse joint. The transverse joints were subjected to direct shear tests, direct tension tests, and flexure tests. These tests exhibited the excellent behavior of the system in terms of strength and failure modes. Shear key tests were also conducted. The shear connection study focused on investigating the composite behavior of the system based on varying the number of shear studs within a respective pocket as well as varying the number of pockets within a respective panel. The results indicated that this shear connection is extremely efficient in rendering the system under full composite action. Finite element analysis was conducted to determine the behavior of the shear connection prior to initiation of the actual full scale tests. In addition, finite element analysis was also performed with respect to the transverse joint tests in an effort to determine the behavior of the joints prior to actual testing. The most significant phase of the project was testing a full-scale model. The bridge was assembled in accordance with the procedures developed as part of the study on full-depth precast panels and the results obtained through this research. The system proved its effectiveness in withstanding the applied loading that exceeded eight times the truck loading in addition to the maximum negative and positive moment application. Only hairline cracking was observed in the deck at the maximum applied load. Of most significance was the fact that full composite action was achieved between the precast panels and the steel supporting system, and the exceptional performance of the transverse joint between adjacent panels.

Book Synopsis Precast Bridge Deck Joints Using FRP and Ultra-high Performance Concrete by : Augustine Kuuku Banson
Download or read book Precast Bridge Deck Joints Using FRP and Ultra-high Performance Concrete written by Augustine Kuuku Banson and published by . This book was released on 2013 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for rapid construction or replacement of highway bridge decks can be addressed by precast concrete elements reinforced with Glass Fiber Reinforced Polymer (GFRP) bars with cast-in-place joints made using Ultra-High Performance Concrete (UHPC). This thesis investigates the bond between GFRP bars and UHPC and splice length optimization to obtain narrow joints and simplified bar geometries. Multiple linear regression analyses of existing bond data indicate that the bar's Young's Modulus and embedded length are the most significant parameters that influence the average bond strength of sand-coated GFRP bars in UHPC: increasing either decreases the average bond strength. Linear-elastic uncracked Finite Element analysis of pull-out specimens indicates that reinforcing bars with low Young's Moduli have highly non-uniform bond distributions along their length and so exhibit high peak bond stresses and low average bond strengths. The higher average bond strengths observed for High Modulus (HM) GFRP bars compared to Low Modulus (LM) GFRP bars is likely because the HM GFRP bars have lower interlaminar shear strength. A methodology for GFRP reinforcement design that synthesizes provisions from the Flexural Design Method in the Canadian Highway Bridge Design Code including an additional new step to determine bar splice lengths in UHPC was developed. Splice lengths and bond resistance factors for HM GFRP bars in UHPC are determined by reliability analysis to resist either bar stresses due to the factored applied moments or the mean ultimate tensile strength of the bar. A significant reduction in splice length can be achieved if splices are designed to resist the bar stresses at factored applied moments. A new resistance factor of 0.5 for bond of GFRP bars in UHPC is also recommended.
