Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The Federal Highway Administration's (FHWA) "Every Day Counts'' initiative aims to shorten the overall project delivery time, enhance safety, and protect the environment both on and around construction projects. Using innovative planning, design, and construction methods, Accelerated Bridge Construction (ABC) techniques reduce on-site construction time for new or replacement bridges. One aspect of ABC is Prefabricated Bridge Elements and Systems (PBES), where bridge components are fabricated offsite to reduce on-site construction activities. Many state departments of transportation, including Florida DOT, are currently making efforts to implement PBES for their bridge construction projects. The purpose of this research project was to investigate other states standards and to evaluate them for possible implementation in Florida. An exhaustive search was made, and new literature was reviewed, to learn about current DOT standards and practices. The search revealed that the states with the most prefabricated bridge standards or activities are as follows: Utah, Alabama, Texas, Minnesota, and a collaboration of Northeastern states. These standards were reviewed for details such as the presence of post-tensioning, joint types, design load, and inspectability. The three standard bridge types that show the most promise for adoption by FDOT are: Florida DOT District 2s Truncated "Florida I-Beam'' (FIB), Minnesotas Inverted Tee Beam, and PCI's "Northeastern Extreme Tee'' (NEXT) Beam. A summary of the findings, including advantages and disadvantages of the bridge systems, is included in this report. Also included is a comprehensive list of web links to standard drawings from all state DOTs, which could also be helpful to expedite other research that involves standards and bridge construction/design practices.

Download or read book Available Accelerated Bridge Construction Options for Short Span Bridges written by Armin Mehrabi and published by Cambridge Scholars Publishing. This book was released on 2024-03-18 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: By employing prefabricated bridge elements and systems, Accelerated Bridge Construction reduces on-site construction time and traffic disruptions, and enhances long-term performance. ABC is particularly advantageous for short-span bridges that are well-suited to standardized prefabrication. In such cases, the entire superstructure and substructure can often be constructed using prefabricated deck elements, modular decks, or systems that span the full bridge width. The construction methods can range from traditional crane installations to Self-Propelled Modular Transport units or slide-in techniques for moving the entire superstructures. This book introduces the concept of ABC and examines its application in the context of short-span bridge construction. It categorizes and details short-span bridges based on various criteria and evaluates the performance of the existing bridges. Decision-making processes regarding the adoption of ABC, choice of elements, systems, and construction methods are also discussed. Additionally, the book covers the inspection of short-span bridges and includes a design example.

Download or read book Connection Details for Prefabricated Bridge Elements and Systems written by Michael P. Culmo and published by . This book was released on 2009 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prefabricated components of a bridge produced off-site can be assembled quickly, and can reduce design time and cost, minimizing forming, minimize lane closure time and/or possibly eliminate the need for a temporary bridge. This document has been developed to promote the use of prefabricated elements and systems in bridges and focuses on 'Connection Details' as part of accelerated construction projects. Accelerated Bridge Construction is one of the prime focus areas of the Office of Infrastructure of Federal Highway Administration. It focuses on a need to create awareness, inform, educate, train, assist and entice State DOTs and their staff in the use of rapid construction techniques. This document represents the State of the Practice at this time with respect to connections between prefabricated elements in accelerated bridge construction projects. Most of the details were obtained from State Departments of Transportation, industry organizations, and private consultants. This information contained herein should be used to develop designs and determine which details would be appropriate for accelerating bridge construction projects.

Download or read book Application of Ultra High Performance Concrete in Prefabricated Bridge Element Connections for Accelerated Bridge Construction written by Daniel Bridi Valentim and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A relatively new type of beam falling under the accelerated bridge construction (ABC) umbrella, the Northeast Extreme Tee (NEXT) D beam, was designed by the PCI Northeast Bridge Technical Committee, with connection details that substitute traditional welded ties joining butted-beam systems, such as bulb-tee girders and double-tee beams. Grout has traditionally been used in joints between prefabricated bridge elements and systems (PBES). This material, however, has resulted in issues with shear key cracking reported by the Federal Highway Administration. An alternative cementitious material, ultra-high performance concrete (UHPC), has been used as a great solution for connections between PBES in ABC. This material exhibits superior properties such as compressive, tensile, and bond strength, durability, and long-term stability when compared to conventional connection materials. Three main studies are presented herein. The first study presents a tensile strength evaluation of 54 UHPC specimens by comparing the direct tension (DT), four-point bending, and double-edge wedge-splitting (DEWS) test methods. No statistically significant difference was found between the peak tensile strengths obtained from DT and DEWS specimens. DEWS specimens are tested using a compression-testing machine, and can be cored and finished from existing UHPC members. The second study evaluates the bond-slip behavior of UHPC and untensioned prestressing strands. The variables studied in the 54 tested pull-out specimens include clear cover, embedment length, and strand diameter (dPT). It was observed that specimens that experienced strand failure had an embedment length of at least 24×dPT or clear cover distance of 2.17×dPT. The third study investigates the behavior of NEXT D beams under fatigue loading. Four double-tee and four slab specimens were subjected to 1 million cycles under AASHTO standard wheel truck loads. Moreover, finite element analyses (FEAs) were performed, effectively simulating the tested specimens, and a 60-ft. long bridge model was created to simulate a constructed bridge in Mobile County, Alabama. It was observed that an 8-in. (203-mm) wide UHPC joint with a single reinforcement layer containing straight #5 bars, an 8-in. (203-mm) embedment length, and spaced every 6 in. (152 mm) had satisfactory performance according to results from experimental testing and FEAs.
