Role of Microcompiuters in Highway Weigh-in-Motion Systems
Microcomputer technology makes it possible to digitize the signals, calculate the desired factors, and record and display the information in real time at the weigh-in-motion (WIM) site....
Microcomputer Assisted Bridge Rating
Before microcomputers can be useful to those officials responsible for rating the approximately 576,000 bridges in this country, software systems must be developed to analyze and rate...
Materials and Member Behavior
Each of the papers in this book covers some aspect of material properties. New developments in cold formed steel are reviewed. The strength, stiffness, and ductility of steel connections...
Bridges and Transmission Line Structures
This volume on Bridges and Transmission Line Structures contains papers from ten sessions and one plenary session of the 1987 ASCE Structures Congress. Eight sessions cover bridges. A...
Rehab Roundup
Four recent rehabilitation projects are described. On an old concrete gravity dam, post-tensioning tendons were added to improve its resistance to sliding. The abandoned Union Station...
Earthquakes Will Not Damage This Bridge
A California pipeline bridge has been retrofitted with isolation bearings that damp earthquake shocks. The bridge over Southern California's Santa Ana River carries the Upper...
Connecticut: A Success Story
The Connecticut Department of Transportation (ConnDOT) had warned the state legislature that its highways and bridges would continue to deteriorate without increased funds for inspection,...
The Wet Look
The collapse of the Schoharie Creek bridge drew attention to underwater inspection. Underwater inspection of bridges gives engineers a better understanding of the condition of the bridges....
Save the Walls
A rehabilitation job in name only, the 75 year old Army and Navy Club, a landmark located in Washington D.C.'s Golden Triangle, retained only two of its 80 ft high exterior...
The Just-in-Case Factor
Computer analysis allows bridge designers to take a more precise look at the old structural principle of redundancy. No one can define redundancy, but everybody knows what it means. Two...
Twisting in the Wind
Wind tunnel tests are being used increasingly to test the aerodynamic stability of bridges. Many designers think these tests should be used early in the conceptual design stage, rather...
Paving with RCC
Roller compacted concrete pavement differs from the RCC used for dams. Since 1984, when the first full scale RCC pavement in the U.S. was installed by the Corps of Engineers at Ft. Hood,...
Concrete Strength Record Jumps 36%
A Seattle building now going up has 19,000 psi concrete, the strongest ever in conventional structures. It costs three times as much as conventional concrete, so will not be widely used....
Wind Loading and Wind-Induced Structural Response
A State-of-the-Art Report
This state-of-the-art report presents fundamental and practical aspects of modern wind engineering practice as it relates to structural design. The first chapter includes information on...
Exhibits Under Fiberglass
The San Diego Convention Center, scheduled for completion in 1988, is located on 11 acres of downtown land only 150 ft from the bay. It will cost $130 million for total of 1.7 million...
Instant Jails
Prison planners are responding to the explosion in the prison population by stepping up construction of new jails. Because of the pressures imposed by court ordered deadlines, engineers,...
Surveying for Scour
The public works engineer never knows exactly how many bridge piers and abutments are undermined by erosion due to scour. Massachusetts Department of Public Works needed a rapid method...
Pipe-lining a Pipeline
This core prestressed concrete cylinder pipe is now lining the inside of a major water supply tunnel in Alaska. Occasionally found in rock tunnels, or buried pipelines, large diameter,...
Milwaukee's Deep Tunnels�No Clone
Tunnel boring machines are excavating nearly 19 miles of tunnels 17-32 ft in diameter as part of Milwaukee's $1.9 billion upgrade of its sanitary sewage system. Laid out to...
Mini Hydro at the Hackett Mills Project
The project includes rehabilitation of a timber crib dam and the first use of a Right Angle Drive turbine in the United States to generate power from the 16 feet of head available at the...
