Book excerpt: The Utah Department of Transportation (UDOT) has implemented the use of precast concrete panels for bridge deck construction. A bridge utilizing these panels as a reconstruction method was decommissioned three years after the new deck installation, due to unrelated matters. Two sections of this bridge were salvaged and sent to Utah State University (USU) for destructive testing. Each bridge section consisted of two built-up steel plate girders intact with the precast concrete deck panels. The precast panels were designed and constructed to achieve full composite action between the deck and built-up steel plate girders through the use of Nelson shear studs. Additionally, the precast panels span the transverse direction and as such have a transverse joint. Historic data has shown the transverse joint to be an area of concern for the functionality of the structural system. Flexure, beam shear, and punching shear of the deck ultimate capacities were compared to those calculated in accordance to the AASTHO Load and Resistance Factor Design (LRFD) Bridge Design Specifications. Various experimental tests considered the affects of the transverse joint on the elastic and plastic capacities and code adherence. Nine destructive tests were performed. The Nelson shear studs were found to be capable of achieving the ultimate capacities of all three types of performed tests and therefore a significant level composite action was attained throughout the experimental tests. The transverse joints show a slight decrease in flexural elastic capacity, no measurable influence on flexural plastic capacity and beam shear ultimate capacity, and a 40% decrease to ultimate punching shear capacity to the deck compared to punching shear capacity without a transverse joint.
Book Synopsis Applications of Partial Depth Precast Concrete Deck Panels on Horizontally Curved Bridges by : Colter Roskos
Download or read book Applications of Partial Depth Precast Concrete Deck Panels on Horizontally Curved Bridges written by Colter Roskos and published by . This book was released on 2018 with total page 1044 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horizontally curved bridges are commonly used for direct connectors at highway intersections as well as other applications. The majority of curved bridges utilize continuous steel curved I-girder or tub girder systems. One of the most critical construction stages from a stability perspective is placement of the wet concrete deck at which point the girders must support the full construction load of the system until the deck stiffens and acts compositely with the girders. Bridges with a curved geometry experience significant torsional forces and require a substantial amount of bracing to control deformation during construction. There are a variety of bracing systems required for bridges during construction. These bracing systems included cross frames and lateral trusses for I-girder systems and top lateral trusses and internal and external cross frames for steel tub girders. While partial depth precast concrete panels (PCPs) are commonly used as stay-in-place formwork for straight bridges, the panels are not currently permitted on horizontally curved girder systems in Texas. TxDOT would like to extend the use of PCPs to bridges with curved girders. This report focuses on the stability of PCPs that rest on polystyrene bedding strips. The project studied the behavior for PCPs with and without a positive connection to steel girders. The experimental portion of this study consists of large-scale PCP shear tests and large-scale combined bending and torsion tests on both a twin steel I-girder system and on a single steel tub girder. The PCP shear tests were used to develop a simple and effective connection between the PCPs and the girder, as well as to empirically determine the in-plane stiffness and strength of the PCP/connection system. The large-scale girder tests were used to investigate the performance of PCPs and their connection to a system that simulates the load experienced in a realistic construction situation. Also, parametric finite element modeling of the PCPs and the curved girder systems were performed and validated with the results from the experimental tests. The finite element models were used to develop an understanding of the fundamental behavior of the steel girder systems in combination with the PCP systems. In addition to focusing on connection methods to the PCPs, guidelines were also developed for cases where the panels can be used on horizontally curved girder systems without a positive connection to the girders

Book Synopsis Design of Plated Structures by : Darko Beg
Download or read book Design of Plated Structures written by Darko Beg and published by John Wiley & Sons. This book was released on 2012-01-09 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main aim of this book is to provide practical advice to designers of plated structures for correct and efficient application of EN 1993-1-5 design rules. In chapter 1 the purpose, the scope and the structure of the book is explained. In chapter 2 a rather detailed and commented overview of EN 1993-1-5 design rules is given following the structure of the standard. Shear lag effect as well as plate buckling problems due to direct stresses, shear forces, transverse forces and interactions of these effects are covered. This chapter also includes a reduced stress method and a finite element analysis approach to plate buckling problems. A large number of design examples illustrate the proper application of individual design rules. Chapter 3 and 4 bring two complete design examples on a crane runway and a box-girder bridge.
Book Synopsis Recommendations for Fatigue Design of Welded Joints and Components by : A. F. Hobbacher
Download or read book Recommendations for Fatigue Design of Welded Joints and Components written by A. F. Hobbacher and published by Springer. This book was released on 2015-12-23 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a basis for the design and analysis of welded components that are subjected to fluctuating forces, to avoid failure by fatigue. It is also a valuable resource for those on boards or commissions who are establishing fatigue design codes. For maximum benefit, readers should already have a working knowledge of the basics of fatigue and fracture mechanics. The purpose of designing a structure taking into consideration the limit state for fatigue damage is to ensure that the performance is satisfactory during the design life and that the survival probability is acceptable. The latter is achieved by the use of appropriate partial safety factors. This document has been prepared as the result of an initiative by Commissions XIII and XV of the International Institute of Welding (IIW).
