New free book offers practical information on design of steel tub girder bridges

CHICAGO, June 2005--Fifty-page, full color, 8½" x 11" book published by the National Steel Bridge Alliance (NSBA) addresses the design of steel tub girder bridges. The book represents a single, comprehensive source of information on steel tub girders. It addresses the entire design process, including layout, design, and detailing, and also offers guidance on construction loading stages.

The book begins with a chapter on the rationale for choosing tub girders as well as application issues. Additional chapters discuss such topics as tub geometries, analysis techniques, diaphragms and bracing, and miscellaneous details. The book concludes with discussions of three example projects. Also included are a comprehensive list of references, an appendix of computer design tools, and an appendix with suggested design details.

Entitled “Practical Steel Tub Girder Design,” the book is available free for download as an Adobe Acrobat file (pdf) from the NSBA website. The entire book (7.3 Mbyte) or individual chapters may be downloaded.
