New Piers for an Old Bridge
Placing new piers under an old superstructure has saved the architecture of the historic Ashley River Bridge in Charleston, S.C. In July 1987, an inspection indicated deterioration and...

People Movers Move Downtown
Although the people mover has become a common sight at major airports in the U.S. and abroad, the sleek high tech vehicles have yet to establish themselves as a cost effective mode of...

Commuter Control
Traffic management systems are a relatively new way to expand the capacity of existing highways and to utilize new ones realistically. Several major systems have been in place and new...

Dallas Urban Goods Movement Changes-The Decade After
In the 1970's, the City of Dallas undertook an urban goods movement (UGM) planning project that resulted by the end of the decade in far reaching changes in the process, particularly...

Economic Impact of Alternative Downtown UGM Strategies
In downtown Dallas, four strategies have been tested: consolidated public truck terminals; provision of off-street loading space in individual buildings, under ordinance; curb space management...

Load-Permit Truck Operations in New York State
This paper presents the results of a survey of indivisible-load permit vehicle operations in New York State. The survey was conducted in the context of an investigation into the impacts...

Truck Involvement in Fatal Urban Road Accidents in Australia
Trucks are over-represented (relative to vehicle numbers and vehicle-kilometers of travel) in fatal accidents. Those most at risk are occupants of other vehicles and pedestrians. Articulated...

Expressway Centerpiece
The center span of the Napoleon Bonaparte Broward Bridge, better known as the Dame Point Bridge over the St. Johns River at Jacksonville, Fla., is the country's longest cable...

Notable Unbuilt Bridges
In the examples of unbuilt bridges discussed, many different ideas and concepts have been proposed. Most appear to be basically sound in nature, although rather innovative and daring....

Aestetics of Bridges Constructed by Dopravni Stavby, Olomouc, Czechoslovakia
A survey of bridge concepts built in recent years by the State Enterprise Dopravni Stavby, Olomouc that ranks among the largest building trade firms in Czechoslovakia. This firm chooses...

Beautiful Bridges and Highways in the West
This paper recounts 75 years of progress in the design of aesthetic bridges and highways in the west. Not a new idea, there are numerous existing examples showing that the goal of good...

An Optimal Design of Steel Pipe Pile Foundation
This paper presents an optimal design method for the steel pipe pile foundation of bridge pier using a nonlinear programming. It is firstly assumed that an imaginary wall model behaves...

Optimization of Cable Prestresses of Cable Stayed Bridges Based on Minimum Strain Energy Criterion
In this study, an attempt is made to determine the optimum cable prestresses based on the strain energy criterion. The validity of the strain energy criterion on the optimum cable prestresses...

Two-Level Optimization of Nonlinear Structures
This paper presents several optimization design problems and their applications to both cable structures and geometrically nonlinear braced-rib arches. The sum of squares of residuals...

BABE: An Expert System for Structural Design of Bridge Abutments and Piers
A knowledge-based expert system named 'BABE' (Bridge and Building Evaluation) has been developed for the purpose of helping the user in planning, analysis and...

Polymer Concretes
Polymer Concrete (PC) is prepared by using polymeric materials to bond inert aggregates in a fashion similar to that of Portland Cement in the preparation of Portland Cement Concrete (PCC)....

Testing of Reinforced Concrete Bridges for External Reinforcement
Several continuous reinforced concrete slab bridges were constructed in the 1950's with spans ranging from 30 ft. to 60 ft. Longitudinal cracks were observed in the tension...
