This report provides specifications, commentary, and examples for the design of horizontally curved concrete box-girder highway bridges. The report details the development of the design procedures. Recommended Load and Resistance Factor Design (LRFD) specifications and design examples illustrating the application of the design methods and specifications are included in appendixes (available on the TRB website at http://trb.org/news/blurb_detail.asp?id=9596).
Specification for design, of steel box girder bridges are proposed for the AASHTO Specification for Highway Bridges. Load Factor Design approach is used. In the design of compression flanges residual stresses and geometric imperfections are considered. For unstiffened flanges a new strength curve is proposed. Strength of stiffened flanges is given as a function of geometric parameters by interaction diagram based on second order analysis. Strength of webs is obtained as a sum of elastic buckling strength, and a lower limit of tension field strength. Web stiffeners are proportioned by strength and rigidity criteria to remain straight up to ultimate web capacity. Also given are rules for design of tension flanges, diaphragms, cross frames and other members, recommended fabrication tolerances and erection provisions. Discussion of principal problems, review of current U.S. and European specifications and commentary are included.
This sourcebook reflects advances in standard design specifications and industry practices. The third edition offers access to reliable data on the material properties of steel, with coverage of the trend towards load- resistance-factor design (LRFD) in both bridges and buildings.
An international team of experts has joined forces to produce the Bridge Engineering Handbook. They address all facets-the planning, design, inspection, construction, and maintenance of a variety of bridge structures-creating a must-have resource for every bridge engineer. This unique, comprehensive reference provides the means to review standard practices and keep abreast of new developments and state-of-the-art practices. Comprising 67 chapters in seven sections, the authors present: Fundamentals: Provides the basic concepts and theory of bridge engineering Superstructure Design: Discusses all types of bridges Substructure Design: Addresses columns, piers, abutments, and foundations Seismic Design: Presents the latest in seismic bridge design Construction and Maintenance: Focuses on the practical issues of bridge structures Special Topics: Offers new and important information and unique solutions Worldwide Practice: Summarizes bridge engineering practices around the world. Discover virtually all you need to know about any type of bridge: Reinforced, Segmental, and Prestressed Concrete Steel beam and plate girder Steel box girder Orthotropic deck Horizontally curved Truss Arch Suspension Cable-stayed Timber Movable Floating Railroad Special attention is given to rehabilitation, retrofit, and maintenance, and the Bridge Engineering Handbook offers over 1,600 tables, charts, and illustrations in ready-to-use format. An abundance of worked-out examples give readers step-by-step design procedures and the section on Worldwide Practice provides a broad and valuable perspective on the "big picture" of bridge engineering.
Indeed, this essential working reference for practicing civil engineers uniquely reflects today's gradual transition from allowable stress design to Load and Resistance Factor Design by presenting LRFD specifications - developed from research requested by AASH-TO and initiated by the NCHRP - which spell out new provisions in areas ranging from load models and load factors to bridge substructure elements and foundations.
