Most highway bridges in North America are designed by the American Association of State Highway and Transportation Officials (AASHTO) specifications. A principal assumption underlying the analysis methods of AASHTO is that bridges of a given type (e.g., slab-on-steel girder bridges) all behave similarly in their live-load distribution properties. By contrast with the North American tradition, bridge analysis in Europe tends to be highly analytical and, usually, computer-based. Such methods as the grillage analogy method, the orthotropic plate method, and the finite element and finite strip methods are extensively used. This book presents a number of simple methods of analysis which expand upon the AASHTO approach, making it consistent with the more refined European methods. The simple methods presented in this book are derived from the results of computer-based rigorous analyses. The book is intended to be useful both to the practicing bridge engineer and to the engineering student. It thus contains both "know-how" and "know-why" material. For the most part the know-why material is to be found in Chapter 1, while the remaining chapters constitute a know how treatment which is virtually complete in itself. The book is also intended to bring home to the reader the physical behavior of bridges of different types and to help the designer in establishing a "feel'' for the mechanisms of load distributions.
