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.

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.

This paper outlines the semi-grillage method of analysis and applies it to slab and pseudo-slab bridge decks. Such an analysis is usually necessary if an economical and efficient design is to be achieved. The method makes use of harmonic analysis and the semi-continuum idealization of Hendry and Jaeger which was later extended by Jaeger and Bakht to include torsion. There are important differences, however. A flexibility formulation has been used which allows torsion, edge stiffening, slab membrane action, sideways deflection of longitudinal beams, and Poisson's ratio to be taken into account. Loads are applied to the supporting members using a simple local statistical distribution as in the grillage analogy method; hence the name give to the method. For the range of bridges to which it is applicable, the proposed method is superior to grillage analysis and requires less work than the finite-strip method. The method can be easily programmed and is ideally suited to a micro-computer. Two examples of plates are presented to illustrate the accuracy, versatility, and ease of use of the method.
