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.

A computer-aided method of analysis is proposed for bridge decks of the horizontally curved pseudo-slab type, using a finite difference formulation for solution of the equilibrium equation of a radially tapered curved plate. For a multi-span continuous curved deck, the method of consistent deformation has been followed. The proposed one-directional difference method is remarkably simple, because it requires nodal equilibrium equations only along the central radial line of the deck. A generalized program was developed from the prescribed methodology, to enable a designer to use this single program to analyze any slab-type bridge deck, whether straight or horizontally curved, simply supported or continuous over a number of piers. For the application of the program to a straight deck, only a large value of the radius of curvature needs to be specified. The analysis is able to take into account the effect of the radial taper of the over-hanging part to the deck slab at the two circumferential edges.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 733: High-Performance/High-Strength Lightweight Concrete for Bridge Girders and Decks presents proposed changes to the American Association of State Highway and Transportation Officials' Load and Resistance Factor Design (LRFD) bridge design and construction specifications to address the use of lightweight concrete in bridge girders and decks. The proposed specifications are designed to help highway agencies evaluate between comparable designs of lightweight and normal weight concrete bridge elements so that an agency's ultimate selection will yield the greatest economic benefit. The attachments contained in the research agency's final report provide elaborations and detail on several aspects of the research. Attachments A and B provide proposed changes to AASHTO LRFD bridge design and bridge construction specifications, respectively; these are included in the print and PDF version of the report. Attachments C through R are available for download below. Attachments C, D, and E contain a detailed literature review, survey results, and a literature summary and the approved work plan, respectively. Attachment C; Attachment D ; Attachment E; Attachments F through M provide details of the experimental program that were not able to be included in the body of this report. Attachment F; Attachment G; Attachment H; Attachment I; Attachment J; Attachment K; Attachment L; Attachment M. Attachments N through Q present design examples of bridges containing lightweight concrete and details of the parametric study. Attachment N; Attachment O; Attachment P; Attachment Q. Attachment R is a detailed reference list."--Publication information.

Bridge decks have traditionally been designed using a simplified model known as the Grillage Analogy Method. Grillage Analogy Method shows how complex structures can be analyzed with physical reasoning and relatively simple computer models, and without complicated mathematics. In recent years the computer methods of grillage has become very popular and accessible as microcomputers and software have developed rapidly. Bridge deck analysis provides bridge designers with the knowledge to understand the behaviour of bridge decks, to be familiar with and to understand the various numerical modeling techniques and to know which technique is best suited to each bridge type. This study focuses on the analysis of the bridge deck using Grillage Analogy Method and Finite Element Method, identifying the effectiveness of Grillage Analogy Method for bridge deck analysis. Tasks being addressed by this case study are the analysis for various types of bridge deck structures which included right angle solid slab deck, skew angle solid slab deck, right angle T-beam bridge deck with 2 end diaphragms, right angle T 8beam bridge deck with 5 diaphragms, skew angle T -beam bridge deck with 2 end diaphragms, curved solid slab deck, single box girder and voided slab deck. The structural details for each bridge deck are further illustrated in each chapter. This study provided information structures that show the percentage differences of the Grillage Analogy Method compared to Finite Element Method in bridge deck analysis using LUSAS Finite Element Software.
