The Cost of Highway Bridge Scour in the State of Minnesota
Different states are faced with different conditions with respect to geology, topography, climate, native vegetation types, bridge ownership, and bridges management systems, which in turn...
Contraction Scour at Bridges: Analytic Model for Coarse-Bed Channels
Contraction scour at bridges spanning coarse-bed channels is evaluated based on mass conservation of both water and transported sediment between a reference channel section near the crossing...
Numerical Simulation of Bridge Abutment Scour Development
This paper reports a project to simulate the development of a local scour hole around a bridge abutment by a computational model. From the prelim inary results obtained, it may be concluded...
Evaluation of Selected Instruments for Monitoring Scour at Bridges in New York
Reliable methods to monitor scour at bridges are needed to ensure public safety and minimize the cost to repair or replace vulnerable bridges. The U.S. Geological Survey, in cooperation...
Design of Guide Banks for Bridge Abutment Protection
As an alternate to designing bridge abutments to withstand the development of the full scour prism predicted by equations currently available for estimating abutment scour, FHWA recommends...
Analysis and Computation
Proceedings papers presented at the ASCE Twelfth Analysis and Computation Conference comprise this volume. Conference sessions covered such topics as: 1) Emerging computing technology;...
Scour Power
New prediction methods consistently calculate scour around bridge piers allowing engineers to better tailor pier design in rock and consolidated material. The leading cause of bridge failure...
Evaluation Findings
the Segmental Concrete Channel Bridge System
Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report presents the findings of a HITEC evaluation of...
Swimming in Style
The Deerfield Academy's new $10 million swimming and squash facility, built in the floodplain of a river, is a jewel-box created from glue-laminated timber, galvanized steel,...
An Irresistible Offer
An unusual case of public-private financing of part of a Florida beltway is described, in which developers along an unfinished section of the road paid for preliminary design that provided...
Rebound of the Bascule Bridge
A patented bascule bridge in Sheboygan, Wis. demonstrates design innovations that reduce the cost of bascule construction and minimize maintenance problems. The new $7.5 million South...
Tappan Zee Set for Inverset (Available only in
Replacing the deck on New York's Tappan Zee Bridge is a ticklish problem, considering that all of the work has to be done at night. A combination of isotropically reinforced...
Reinforced Glued Laminated Timber
In record time, reinforced glued laminated timber (glulam) has moved from an experimental product to wide-spread commercial acceptance. Several case studies illustrate applications and...
Balancing on the Tides
Using a system of pivoting, barge-mounted towers, a Virginia contractor floated bridge segments into position 120 ft above the York River, reducing costs and cutting erection time by nearly...
Marine Borers Are Back
Cleaning up the nation's harbors has brought a resurgence in marine borer activity. These organisms, mainly the teredo and the limnoria, eat at timber piers, undermining critical...
Seeking Structural Solutions
A photo essay on the unique work of Santiago Calatrava, a Spanish-born engineer and architect whose bridges and buildings have attracted international attention for their unusual esthetics....
Singapore Showcase
A new bridge in Singapore has a unique pylon design and no piers. The deck hangs from the pylon supported by three back stays. The 100 m overpass bridge was designed for the Singapore...
Alluring Approach
A new bridge over the White River in Columbus, Ind., is a unique, architecturally appealing cable-stay, concrete-and-steel structure. The bridge satisfies municipal officials'...
Portland's Light Rail Goes Underground
A 29-km extension of Portland's first modern light rail system nears completion. The extension includes a 4.6 km twin-tunnel section and the deepest transit station in North...
