Behavior and Design of Trapezoidally Corrugated Web Girders for Bridge Construction

Book excerpt: Corrugated web girders (CWGs), used for bridge construction, differ in important ways from conventional prismatic girders. Behavior and Design of Trapezoidally Corrugated Web Girders for Bridge Construction details the behavior and design of CWGs in bridge construction and includes unique research into high-strength steel. The title gives a comprehensive review of the last decade in CWG design. In-depth explanations of key concepts are given — such as the accordion effect — that differentiate these girders from more conventional flat-webbed girders, and the authors also present specialized research into tubular flanged girders. The book distinguishes between prismatic and tapered CWGs, explains failure modes under both shear and flexure, and gives clear figures to illustrate these modes. The volume compares international building codes and offers recommendations for future research. Seven chapters cover –– An introduction to CWGs for bridge construction; Development of bridges with corrugated webs; Real boundary conditions between flange and web; Shear buckling behavior; Flexural buckling behavior; Recent erection methods and; Future research. - Enables the reader to understand advances and future directions in the behavior and design of CWGs for bridge building - Reviews advances in the behavior and design of CWGs - Explains concepts which make these girders different from conventional flat-webbed girders - Distinguishes between the behavior of prismatic and tapered CWGs - Considers the failure modes of girders under shear and flexure, as well as ultimate strength - Compares international codes — such as Eurocode 3 — in useful technical detail
