Friant Power Project: Design and Construction?Non-Federal Power at a Reclamation Facility
Friant Dam, Millerton Reservoir, provides the principal water supply for the Friant Division Central Valley Project of the U. S. Bureau of Reclamation (Bureau). The dam is a 319-foot high...
Iceberg Impact Load on a Gravity Based Structure
The mechanics of the eccentric collision of an iceberg against a fixed, rigid, gravity based structure are discussed. A closed form solution is derived for the case of infinite friction...
Controlling Sulfide Corrosion in Large Diameter Gravity Sewers (
The County Sanitation Districts of Los Angeles County undertook a major evaluation of sewer system ranging in size from 1. 22 to 3. 65 meters in diameter that transports peak wastewater...
Record High Rise, Record Low Steel
The Bank of China, under construction in Hong Kong, will be the world's fifth tallest building. In spite of the extraordinary codes for that city�high winds, and high live...
Alternate Sewers�No Longer Alternate
The term alternate sewers means those used where neither conventional gravity sanitary sewers will suffice, nor will the septic tank/leach field system. In such situations, usually one...
Probabilistic Limit States Design of Moment-Resistant Frames Under Seismic Loading
This paper focuses on the development of a methodology for the optimal probabilistic limit states design of seismic-resistant steel frames. A mechanism for allowing the designer to include...
A Study of Exterior Facades?Problems and Solutions
The quality of the exterior facades of a building is important to maintaining aesthetic image, protecting the interior environment from infiltration of heat, cold, moisture, wind, and...
Optimal Design of Sanitary Sewers
Virtually all recent research has been on conventional gravity sewers without pumping. A variety of optimization techniques has been used, including linear programming, nonlinear programming,...
Complexity in Concrete
Centrust Tower in Miami, Fla., is a $95 million, 37 story, 600,000 sq ft tower rising from one side of a block-square 11 story parking garage. Columns on the curved side of the triangular...
Strength-Deformation Properties of Arctic Silt
Hydrocarbon exploration and production activities in the Beaufort Sea require construction of gravity structures capable of withstanding extremely large ice loads at sites where the subsea...
Cyclic Multiaxial Cubical Cell Experiments on a Norton Sound Silt
A servo-controlled multiaxial cubical test apparatus has recently been used to investigate the behavior of the foundation soil for a gravity structure in Norton Sound of the Alaska Outer...
Foundation Response of Arctic Structures to Time-Dependent Ice Loadings
Arctic structures are subjected to a variety of time-dependent loadings, the most important of which are those due to ice. An approach is presented for estimating the strength and deformation...
Use of Asphalt in Treatment of Dam Foundation Leakage, Stewartsville Dam
This paper presents the recent development and application of a hot asphalt grouting technique used to stop a 5,000 Imperial Gallons Per Minute (IGPM) (22,000 lpm) dam leakage under full...
New Ways with Concrete
When NASA builds on the moon and in space, the structures will be concrete, say researchers at the Portland Cement Association's Construction Technology Laboratories. They...
Reliability of Urban Water Supply Reservoir System
Assessment of the reliability, or risk of failure, of water supply reservoirs is dependent on several factors including reservoir volume, probability of dam failure and drought inflows....
Roller Compacted Concrete
Roller compacted concrete has emerged recently as an economical material and rapid method of construction for use in gravity dams, overflow structures and heavy duty pavements. The economics...
Nonlinear Deformation and Bispectral Change of Random Gravity Waves on Sloping Bed
A WKB-perturbation method is applied to the deformation of random gravity waves in water of slowly varying depth. In the present analysis, a spectral representation of WKB-type is assumed...
Staggered Truss Adapted to High Rise
The 34-floor Nashville Convention Center Hotel required a structural system that would overcome the tendency to vibrate in the wind. The solution was a modified staggered frame truss,...
Economic Considerations in Selection of a Roller Compacted Concrete Dam
Roller compacted concrete (RCC) has recently emerged as an economically attractive material for gravity dam construction, replacing the use of conventional concrete and even challenging...
High Rise Design: Accounting for Column Length Changes
In the late 1950's and early 1960's, the height of concrete buildings jumped from 20 to 60 stories. During the same period, architects introduced the use of exposed...
