Analysis of Skew Ribbed Bridge Decks by Grillage Methods: Structural Analysis

The book having introduction in chapter one. Many related works are reviewed in chapter two. Successful applications of these method are presented and notes on comparison are given in the same chapter . Chapter three presents a comprehensive treatment of the grillage analogies. Significant aspects such as the section propeties, shear lag effect, grillage mesh geometry and other factors are investigated . The skew ( or oblique ) grid framework method is developed in chapter four. Advantages and disadvantages of this method are reviewed with appropriate proposed equations and suggested procedure for calculations. Comparison grillage and grid framework method with published experimental and theoretical results appear in chapter five. Also certain examples are solved by the finite element methods for assessing the accuracy and efficiency of the proposed methods. The application of the grillage method for the analysis of different cases appears in chapter six. Chapter seven gives the conclusions and presents ideas for future works.
