Dams Reborn
The need to rehabilitate dams without draining their valuable reservoirs is impacting the way the Bureau of Reclamation makes modifications. There are no two better examples of this than...
Steel Structures
The seventy-eight papers included in this volume cover the fifteen sessions generally associated with steel structures presented at the Seventh Annual Structures Congress held on May 1-5,...
Underwater Tunnel Inspection by Virginia Power Using a Submersible Robot
The Bath County Pumped Storage Station, has three large tunnels linking the upper and lower reservoirs. The 'Hydrover' submersible remotely operated vehicle (ROV)...
Underwater Tunnel Inspection by Virginia Power Using a Submersible Robot
The Bath County Pumped Storage Station, jointly owned by Virginia Power and Allegheny Power systems and operated by Virginia Power, has three large tunnels linking the upper and lower...
Automated People Movers II
New Links for Land Use?Automated People Mover Opportunities for Major Activity Centers
This Proceedings, which consists of 94 papers presented at the Second International Conference on Automated People Movers (APM's) held in Miami, Florida on March 13-15, 1989,...
Fire Protection at the Grand Coulee Hydro Project
In the fall of 1980 a rupture of one of the Project's 525kV transmission cables occurred and created a fire. Power from three Third Powerplant 700MW units was interrupted,...
The Design and Operating Experience of a Multiplexer Application in Conventional Hydro Powerhouse Control
The design of the Bonneville Second Powerhouse control system presented an opportunity to replace conventional cables with a multiplexer system that would provide a two-way data communication...
On the Post-Flutter State of Cable-Stayed Bridges
This paper deals with the post-flutter vibrations of cable-stayed bridges. An approximate theory and an approximate analytical solution method have been established. A numerical example,...
Burlington Cable-Stayed Bridge
The Burlington cable-stayed bridge will carry US34 over the Mississippi River from Burlington, Iowa to Gulfport, Illinois. There will be two 12-ft lanes in each direction plus an acceleration...
Quincy Bayview Bridge?Construction Control
A cable-stayed bridge crossing the Mississippi River at Quincy, Illinois, was completed in August 1987. The structure includes twin concrete towers and a hybrid deck section. The cable...
New Parallel Wire Bundle for Cable-Stayed Bridges
A parallel wire bundle is described which is twisted with a long lay length. It is corrosion protected by an inner fill and outer coating of polyurethane. It presents a specially shaped,...
Skytrain Crosses the River
The cable stayed bridge that will carry Vancouver's light rail line across the Fraser River is the world's longest such bridge built solely for mass transit....
Pipe Geometry and Pipeline Bridge Wind Oscillation
Static and modal analyses of two pipeline suspension bridges owned by American Natural Resources - the Patterson Loop Aerial Crossing (PLAC) with a span of 850 feet (259 meters) and the...
Cables in Trouble
Having inspected more than half of the world's cable stayed bridges, the authors conclude that many are in danger of sudden collapse unless corrosion problems can be stopped....
Cable Stayed Bridges
Two of these five papers on cable-stayed bridges deal with wind analysis. One develops the theory for motion due to flutter and reaches the conclusion that the vibrations are, in general,...
A Portable Bowen Ratio System for ET Measurements
The AZET system developed at the University of Arizona is designed to measure evapotranspiration (ET) in arid zone environments, using the Bowen ratio model. The system consists of a set...
Lunar Resources: What is Known and Expected
The lunar regolith is the source of a number of basic materials which can be utilized in lunar construction. These materials include those which are obtained directly from the regolith...
A New Lake and a Beautiful Bridge
The two 1988 OCEA awards of merit are the Great Salt Lake west desert pumping project and the Sunshine Skyway near Tampa, FL. Both projects were constructed fairly quickly. The pumping...
The Williamsburg: Rehab After All
Whether to repair or replace the Williamsburg Bridge has been seriously debated in New York City for years. Recently, a blue ribbon panel of technical advisors appointed by the Mayor conducted...
Long Distance Dam Data
Remote data collection systems are increasingly being used for dams. Instrumentation of structures for obtaining data on performance is not new. However, automation and computerization...
