Extending the Service Life of Existing Bridges by Increasing Their Load Carrying Capacity


Book Description

A catalog of bridge deficiencies is developed based on the inspection of over 140 deficient bridges located in Illinois, Florida, Pennsylvania, California, and Tennessee. A classification of structure types is developed for concrete, steel and timber bridges. Deficiencies are related to the structure classification system and a hierarchy of the most common deficiencies established. Techniques presently utilized by state highway departments to correct deficiences are described and evaluated. Several innovative techniques for increasing the load carrying capacity are also described. Utilizing these techniques, increased capacity values are developed. Cost factors are also analyzed and graphic presentations which show the relative merit of each system are presented.

Bridge Engineering Handbook


Book Description

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.

Methods of Modifying Historic Bridges for Contemporary Use


Book Description

Studied by a team of experts in the fields of history, bridge engineering, architecture, and computer analysis were 21 old truss bridges of historical importance located in Virginia. These old bridges are narrow and have low load-carrying capacities, making them targets for replacement and destruction. On a case-by-case basis, the bridges were investigated as to their potentials for strengthening and widening for normal vehicular use. Also explored were non-vehicular uses as for conversion into craft centers, museums, restaurants, housing, bicycle structures, and the like, at either the present site or a new one. The wide array of possibilities for continued use of the old bridges described in this report show that old bridges do indeed have much useful life left in them and it is not always necessary that they be demolished.
