Book excerpt: The major focus of this research was to validate the concept of connecting two adjacent simple-span girders with a link slab to form a jointless bridge deck so as to eliminate the standard deck joint between the girders. Laboratory tests were conducted on two large-scale specimens to study the performance of the link slab and the girders. The test results indicated that the contribution of link slab to structural continuity is negligible since the stiffness of the link slab is much less than that of the beams with composite decks. Therefore the beams can be treated as simply supported structures without considering the link slab. Furthermore, the stresses in the link slab are controlled primarily by the predominant bending effect due to the end rotations of the beams rather than the axial load effect. A simplified method of analysis is proposed in which the end rotations of the two adjacent girders under a given loading are determined first. Then the end rotations are imposed on the ends of the link slab and the induced moment in the link slab is thus calculated. A design guideline for the link slab is also proposed and illustrated by a design example. The reinforcement for the link slab is designed to control the crack width in the link slab according to the AASHTO criterion.

Book excerpt: Costs of replacement and maintenance of expansion joints are often a large part of the costs associated with bridge maintenance. To replace these expansion joints or eliminate some of them on structures could greatly reduce the costs. Link slab is a new design approach, which could replace the traditional expansion joints. A link slab is the portion of the bridge deck that connects two adjacent simple-span girders. Link slabs also reduce the damage to the substructure of bridges due to water penetration and debris accumulation in the expansion joint. The objective of this research is to validate the design assumptions associated with designing link slabs, investigate a limit states design procedure and develop a program for the long-term monitoring of an instrumented link slab. This thesis provides details about testing and analysis, which were useful in accomplishing the research objectives. It also provides information about the datalogger software that was used in this project and also details the computer program that was written in Microsoft Excel to aid in the data collection and sorting.

Available in PDF, EPUB and Kindle. Book excerpt: Bridge Superstructure deals with the behaviour of different types of bridge decks under different systems of loading. Mathematical modeling and the behaviour of different types of bridge decks are clearly explained. Solid slab, voided slab and skew slab bridge decks are detailed out for analysis and design. Box girder bridges is specially discussed for better understanding of its behaviour and its design. Special points relating to creep and shrinkage effects in continuous bridge decks are explained. Bridge bearings, expansion joints and appurtenances of different types are explained with respect to their place of use and their functions. A few methods of erection of bridge decks of simply supported spans or continuous spans are presented to give a good understanding of such possibilities.

Download or read book Grillage Analogy in Bridge Deck Analysis written by C. S. Surana and published by Alpha Science Int'l Ltd.. This book was released on 1998 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the well established computer-aided method of grillage analogy as applied to analysis of bridge decks. The method, applicable to various types of bridge decks (such as slab bridges, T-beam bridges and box-girder bridges), can handle rigid or flexible support conditions, and right, skew or curved plan layouts.The procedure and recommendations for idealising the actual bridge decks and loadings into mathematical models are discussed. Two programs, given in ready-to-use form, along with descriptions of various subroutines, can analyse a variety of bridge decks accurately and obtain all the responses required in the design. Their uses are explained through worked-out examples. These programs, along with input-data and exhaustive output results of all the worked-out examples, are also available on a diskette and can be ordered seperately from the authors through the publisher. This will help those who do not want to type programs from the book and run into possible risk of errors.The book will be useful for the students, researchers, teachers, designers and consultants engaged in analysing, designing, vetting, tendering or constructing bridges.

This book was released on 1989 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents and presents results of a study to determine time-dependent behavior and relevant design criteria for simple-span precast, prestressed bridge girders made continuous. A questionnaire was used to determine current practice. Creep and shrinkage tests of steam-cured concrete loaded at an early age were made. Computer simulations were used to investigate the effects of time-dependent material behavior and variation in design parameters on the effective continuity for live load plus impact. The findings suggest that positive moment connections in the diaphragms at the piers are not required and provide no structural advantages. The findings also suggest that effective continuity for live load plus impact can vary from 0 to 100% dependent on the design parameters and timing of construction. Computer analyses were also used to determine an upper limit for the amount of negative moment reinforcement over the supports to insure full moment redistribution and attainment of maximum bridge strength. New computer programs were developed for simplified analysis to determine time-dependent effects and service moments. Recommendations for design procedures were presented and design examples given.

This book was released on 2011 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to evaluate the performance history of continuous bridge decks in the State of Georgia, to determine why the current design detail works, to recommend a new design detail, and to recommend the maximum and/or optimum lengths of continuous bridge decks. The continuous bridge decks have continuous reinforcement over the junction of two edge beams with a construction joint for crack control. The current technical literature and current practices and design procedures were synthesized and summarized. GDOT maintenance reports were reviewed, and preliminary field evaluations were conducted to determine the performance of the continuous deck detail. The effects of bridge movement due to thermal strains, shrinkage, and live loads were considered in simplified analytical studies to better understand the demands placed on the GDOT continuous deck detail. A summary of the preliminary design and length recommendations are provided upon completion of Part 1 of the research.
