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.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research was performed to develop and test a new type of full-width partial-depth precast concrete panel (PCP) deck system for Texas bridge decks that can be implemented at the bridge overhangs. Twenty-four full-scale PCP specimens with embedded wire trusses were load tested. Test variables included specimen geometry, reinforcement detailing, and fabrication technique for the welded wire trusses. Results showed that the design generally performed in a ductile and relatively well-predicted manner using static analysis techniques. Specimens tended to reach a load plateau before failure. Some specimens with longer unbraced truss lengths tended to buckle after reaching a load plateau. Specimens with lower-strength trusses tended to avoid buckling-type failures altogether. Bundling additional reinforcing bars to the bottom chord also completely prevented buckling

This book was released on 2007 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precast bridge deck panels can be used in place of a cast-in-place concrete deck to reduce bridge closure times for deck replacements or new bridge construction. The panels are prefabricated at a precasting plant providing optimal casting and curing conditions, which should result in highly durable decks. Precast panels can be either full-depth or partial-depth. Partial-depth panels act as a stay-in-place form for a cast-in-place concrete topping. This study investigated only the behavior of full-depth precast panels. The research described in this report had two primary objectives. The first was to develop a performance specification for the grout that fills the haunch between the top of the beam and the bottom of the deck panel, as well as the horizontal shear connector pockets and the panel-to-panel joints. Tests were performed using standard or modified ASTM tests to determine basic material properties on eight types of grout. The grouts were also used in tests that approximated the conditions in a deck panel system. Based on these tests, requirements for shrinkage, compressive strength, and flow were established for the grouts. It was more difficult to establish a test method and an acceptable performance level for adhesion, an important property for the strength and durability of the deck panel system. The second objective was to quantify the horizontal shear strength of the connection between the deck panel and the beam prestressed concrete beams. This portion of the research also investigated innovative methods of creating the connection. Push-off tests were conducted using several types of grout and a variety of connections. These tests were used to develop equations for the horizontal shear strength of the details. Two promising alternate connections, the hidden pocket detail and the shear stud detail, were tested for constructibility and strength. The final outcome of this study a set of recommendations for the design, detailing, and construction of the connection between full-depth precast deck panels and prestressed concrete I-beams. If designed and constructed properly, the deck panel system is an excellent option when rapid bridge deck construction or replacement is required.

Available in PDF, EPUB and Kindle. Book excerpt: Throughout the United States accelerated bridge construction is becoming increasingly popular to meet growing transportation demands while keeping construction time and costs to a minimum. This research focuses on eliminating the need to form full-depth concrete bridge deck overhangs, accelerating the construction of concrete bridge decks, by using full-depth precast prestressed concrete deck panels. Full-depth precast overhang panels in combination with cast-in-place (CIP) reinforced concrete are experimentally and analytically investigated to assess the structural performance. Experimental loaddeformation behavior for factored AASHTO LRFD design load limits is examined followed by the collapse capacity of the panel-to-panel seam that exists in the system. Adequate strength and stiffness of the proposed full-depth panels deem the design safe for implementation for the Rock Creek Bridge in Fort Worth, Texas. New failure theories are derived for interior and exterior bridge deck spans as present code-based predictions provide poor estimates of the ultimate capacity. A compound shear-flexure failure occurs at interior bays between the CIP topping and stay-in-place (SIP) panel. Overhang failure loads are characterized as a mixed failure of flexure on the loaded panel and shear at the panel-to-panel seam. Based on these results design recommendations are presented to optimize the reinforcing steel layout used in concrete bridge decks.
Book Synopsis Eliminating Rebar Splicing in Transverse Joints of Precast Full Depth Bridge Deck Panels by : David M. Gee
Download or read book Eliminating Rebar Splicing in Transverse Joints of Precast Full Depth Bridge Deck Panels written by David M. Gee and published by . This book was released on 2020 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study looks at the removal of longitudinal rebar splicing when sufficient longitudinal post-tensioning is provided for full-depth precast deck panels for simply supported bridges. Full-depth precast prestressed concrete deck panels are high quality plant produced pretensioned panels. They are often post-tensioned at the site to provide an average net compression in the joint of at least 250 psi due to effective prestress. This is to ensure adequate transfer of load as truck wheels pass over the joint. This net compression on the transverse joint is not explicitly clear by the AASHTO LRFD Bridge Design Specifications. Based on this section, it is unclear if the use of post-tensioning that provides a net compression of at least 250 psi at the joint, due to effective prestress, still requires the coupling of rebars over the transverse joint. However, in cast-in-place deck construction, no longitudinal post-tensioning is generally introduced and no transverse joint is required. It is a requirement of the ASSHTO LRFD Bridge Design Specifications that secondary reinforcement be placed continuously along the direction of traffic. Following the empirical deck design in AASHTO, two-thirds of the primary transverse reinforcement should be provided for secondary longitudinal reinforcement. The problem is observed when a number of designers insist on strictly following the code for full-depth precast deck panel designs without considering the impact of longitudinal post-tensioning and naively emulating cast-in-place practice without taking full advantage of precast concrete. Although providing secondary reinforcement for each precast panel is possible, the number of splices and the number of pockets for field splicing due to these extended bars become a significant challenge to this type of construction. By using sufficient net compression at the joint, rebar splicing can be removed. The objective of this research is to investigate the post-tensioning level required to eliminate rebar splices in transverse joints for full-depth precast deck panels. Two full scale full-depth precast deck panels were post-tensioned to multiple levels varying the net compression at the joint between 100 to 350 psi. Static tests with a point load simulating one-wheel load of the 32-kip axle multiplied by the dynamic allowance factor (1.75 for the deck joint) was applied to the panel-to-panel connection joint for various post-tensioning levels. The test results show that when a net compression of at least 300 psi is applied at the transverse joint, rebar splicing is not needed. This is supported by the lack of cracking that occurs when applying the 32-kip loading along the joint. Testing along the longitudinal joint was also conducted as a separate research topic, and some of the results are presented. The main objective of this testing was to determine the viability of using a staggered rebar joint with a minimal joint width. This was accomplished by using ultra-high-performance concrete (UHPC) and self-consolidating concrete (SCC) with steel fibers to enhance the ductility and strength of the joint. By using a joint that gives sufficient development length of the bars, which is shorter for fiber reinforced concretes, it is shown that the joint detailing is adequate for service loadings.

Book Synopsis Structural Concrete Overlays in Bridge Deck Rehabilitation by : Frieder Seible
Download or read book Structural Concrete Overlays in Bridge Deck Rehabilitation written by Frieder Seible and published by . This book was released on 1988 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Full depth structural concrete overlays are commonly used in bridge deck repair and rehabilitation. Beneficial structural effects, such as increase in structural depth, can only be considered in the design if monolithic action of the overlaid slab can be assured beyond the flexural ultimate limit state of the bridge deck. A three phase experimental program to study the effect of different surface preparations and dowels between the "old" deck and the overlay on the overall bridge deck behavior under service loads (monotonic, cyclic, dynamic), overloads and ultimate limit state loads is presented in this report. The three test phases comprised triplet shear block tests, full scale transverse deck slab panel test (simply supported and continuous) as well as the full scale prototype testing of a 60 ft long highway bridge section (Gepford Overhead) which had been in service for 25 years prior to being repaired and tested under laboratory conditions. A summary of experimental results is presented in this report together with comparative studies and comprehensive design recommendations.

This book was released on 2008 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: A bridge with precast bridge deck panels was built at the Virginia Tech Structures Laboratory to examine constructibility issues, creep and shrinkage behavior, and strength and fatigue performance of transverse joints, different types of shear connectors, and different shear pocket spacings. The bridge consisted of two AASHTO type II girders, 40 ft long and simply supported, and five precast bridge deck panels. Two of the transverse joints were epoxied male-female joints and the other two transverse joints were grouted female-female joints. Two different pocket spacings were studied: 4 ft pocket spacing and 2 ft pocket spacing. Two different shear connector types were studied: hooked reinforcing bars and a new shear stud detail that can be used with concrete girders. The construction process was well documented. The changes in strain in the girders and deck were examined and compared to a finite element model to examine the effects of differential creep and shrinkage. After the finite element model verification study, the model was used to predict the long term stresses in the deck and determine if the initial level of post-tensioning was adequate to keep the transverse joints in compression throughout the estimated service life of the bridge. Cyclic loading tests and flexural strength tests were performed to examine performance of the different pocket spacings, shear connector types and transverse joint configurations. A finite element study examined the performance of the AASHTO LRFD shear friction equation for the design of the horizontal shear connectors. The initial level of post-tensioning in the bridge was adequate to keep the transverse joints in compression throughout the service life of the bridge. Both types of pocket spacings and shear connectors performed exceptionally well. The AASHTO LRFD shear friction equation was shown to be applicable to deck panel systems and was conservative for determining the number of shear connectors required in each pocket. A recommended design and detailing procedure was developed for the shear connectors and shear pockets.
