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.

Download or read book Prestressed Concrete Bridges written by Nigel R. Hewson and published by Thomas Telford. This book was released on 2003 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prestressed concrete decks are commonly used for bridges with spans between 25m and 450m and provide economic, durable and aesthetic solutions in most situations where bridges are needed. Concrete remains the most common material for bridge construction around the world, and prestressed concrete is frequently the material of choice. Extensively illustrated throughout, this invaluable book brings together all aspects of designing prestressed concrete bridge decks into one comprehensive volume. The book clearly explains the principles behind both the design and construction of prestressed concrete bridges, illustrating the interaction between the two. It covers all the different types of deck arrangement and the construction techniques used, ranging from in-situ slabs and precast beams; segmental construction and launched bridges; and cable-stayed structures. Included throughout the book are many examples of the different types of prestressed concrete decks used, with the design aspects of each discussed along with the general analysis and design process. Detailed descriptions of the prestressing components and systems used are also included. Prestressed Concrete Bridges is an essential reference book for both the experienced engineer and graduate who want to learn more about the subject.

This book was released on 2017 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the leading causes of structural deficiencies in the United States Bridge Inventory is related to deterioration and durability problems with concrete bridge decks (NCHRP 2004). The primary issue with bridge decks is related to cracking of the concrete that provides a direct conduit for moisture and other corrosion agents to permeate and attack the reinforcing steel. Adequate reinforcing steel is needed in the deck to minimize crack widths and therefore limit corrosion of reinforcing steel. A particular case of interest occurs when the bridge deck is constructed using partial-depth precast concrete deck panels (PCP) with cast-in-place (CIP) concrete topping. When this type of deck construction is used over the negative moment region of continuous steel or concrete girders, the amount of reinforcing steel that should be placed within the CIP concrete topping to provide adequate crack control is not currently well understood. This thesis is part of a larger study being conducted for the Texas Department of Transportation that is examining this issue. In the study reported in this thesis, two newly constructed bridges were instrumented to monitor the behavior of the bridge deck. These bridges did not use continuous girders, but rather had simply supported prestressed concrete girders, with a bridge deck constructed using a “poor-boy” construction joint detail over interior bents. Each bridge utilized three different reinforcement layouts centered over an interior bent within the poor-boy joint detail. Strain gages in each portion provided constant readings to display the distribution of strain across the bridge deck. Each bridge was monitored over a period from when the deck was cast until when the bridge was opened to traffic. Live load tests were also conducted to provide data on strains induced by heavy trucks. Based on the field data, no clear correlation was found between the amount of steel added and the strain measured. However, based on the measured data combined with field observations of cracking, the current standard reinforcement appears to be adequate in controlling the crack widths for the poor-boy deck detail. While the poor-boy deck joint detail is different from deck details used over negative moment regions of continuous girders, this data provides useful insights in to bridge deck behavior that will help guide future phases of the larger study.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The report illustrates and evaluates the first use in Virginia of precast concrete replacement slabs for bridge decks. It shows that a bridge deck can be replaced with the precast slabs while traffic is maintained in the adjacent traffic lane. The quality of the prototype deck appears to be comparable to that of a conventional site-cast deck and, although a conventional deck could be constructed for slightly less money, the new design offers the advantage of reduced on-site construction time that would be worth the added cost in many situations.

Download or read book Design Recommendations for CIP-PCP Bridge Decks written by Ki Yeon Kwon and published by . This book was released on 2012 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precast, prestressed concrete panels (PCPs) and cast-in-place (CIP) concrete slabs are commonly used in Texas and elsewhere. Because PCPs are placed between bridge girders, and CIP concrete slabs are cast over the PCPs, PCPs act as formwork, cost and time for construction can be reduced. However, current designs may be further optimized if it can be shown that the reinforcement in the CIP deck can be reduced. Another issue involves cracking of PCP during fabrication and transportation to the site. The goal of this dissertation is to recommend changes to the CIP-PCP bridge decks that will lead to more cost-effective bridges. The first phase of the research is to suggest an optimized reinforcement layout for cast-in-place (CIP) slabs. Because the capacity of these decks is much greater than the design loads, a decrease in top-mat reinforcement will have minimal effect on the margin of capacity over design loads. Two options were selected, reduced deformed-bar reinforcement; and reduced welded-wire reinforcement. These two options are evaluated through restrained-shrinkage tests and field applications. The second phase of this dissertation is to reduce cracks in precast, prestressed concrete panels (PCPs) which occur during fabrication, handling, and transportation. Most cracks in PCPs are collinear (occur along the strands). They can be reduced in two ways. The first is to reduce initial prestress. The second is to place additional transverse reinforcement at edges.
