Roller Compacted Concrete Arch/Gravity Dams?South African Experience
The paper traces the development of roller compacted concrete (RCC) dams in South Africa, and in particular the application to arch/gravity dams. The Department of Water Affairs and Forestry...
The Design and Construction of Shuikou Project RCC Diversion Wall
Shuikou Hydroelectric Project, currently under construction on the Minjiang River in the People's Republic of China is a concrete gravity dam having a maximum height of 101...
A Review of Design Criteria for High RCC Dams
The 1980s could be considered to be the decade during which roller-compacted concrete dams came of age. This economic method of construction is sufficiently proven that very large dams...
Performance of Upper Stillwater Dam
Upper Stillwater Dam was constructed with roller compacted concrete (RCC) and horizontally slipformed facing. This unique construction method for a concrete gravity dam included no contraction...
Roller Compacted Concrete Tailing Retention Dam
A roller compacted concrete (RCC) dam has been designed for gold tailing impoundment in southeast Alaska. To minimize up front capital costs, the curved gravity dam with multiple outlet...
Concepcion Dam Design & Construction Problems and Their Solutions
Concepcion Dam is a curved axis gravity structure 68 m high and 695 m long. It supplies water to Tegucigalpa, the capital of Honduras. The dam contains 290,000 cubic meters of RCC. Challenges...
Final Design and Construction of Gibraltar Dam Strengthening
The results of a 1983 safety evaluation of Gibraltar Dam indicated that the dam did not meet seismic safety standards. A remedial scheme involving the addition of a roller compacted concrete...
Two Basic Concepts in Offshore Engineering
Two concepts are developed which lead to an improved understanding of the characteristics of the wave forces that act on deep-water, jacket-type offshore structures. The first concept...
Wind Effect on Oblique Motion of Two Bodies in a Uniform Flow
The wind effect on the general translational motion of a circular cylinder through an inviscid and incompressible fluid, conveyed by a uniform flow at infinity, in the vicinity of another...
The Generalized Brazier Problem for Orthotropic Straight Tubes of Finite Length
A new engineering approach, based upon a mixed variational functional, is presented for the analysis of the nonlinear static behavior of thin-walled, circular-cross-section cylindrical...
Mechanics of Granular Materials at Very Low Effective Stress Levels
Gravity's influence on laboratory specimens of uncemented granular materials subjected to low effective stresses, makes it impossible to evaluate constitutive properties in an unambiguous...
Stability of Beams in Eccentrically Braced Frames
As the link yields and strain hardens in an eccentrically braced frame, the beam segment-outside of the link is subject to a combination of high axial force and bending moment. For certain...
The Proposed NASA Lunar-Based Astronomical Observatories
The goals of the Space Exploration Initiative are a manned return to the Moon, a permanent lunar outpost and then a manned expedition to Mars. This presents an opportunity to construct...
The Army Aviation Team from a Military Civil Engineer's Perspective
The Technical Session for which this paper is written is 'Airfield Pavements - A Team Effort.' As such, the emphasis on this paper is the United States Army Aviation Team, and not the...
Modeling Nearshore Currents in the Vicinity of the Endicott Causeway, Alaska
The Endicott Causeway connects two oil production islands on the southern side of Stefansson Sound, about 5 km offshore of the Sagavanirktok River delta, to the mainland of the Alaskan...
A Three-Dimensional Simulation of Buoyancy and Wind-Induced Circulation and Mixing in the New York Bight
A three-dimensional simulation of the circulation and mixing in the New York Bight has been conducted, forced by (i) wind stress for the year 1987 and monthly-mean heat fluxes at the sea...
Estimates of Extreme Wind Distribution Tails
The assumption that extreme winds have a Gumbel distribution appears to yield unrealistically high failure probability estimates for wind-sensitive structures. For this reason we study...
Sampling Errors in U. S. Extreme Wind Records
A study of design level extreme wind speeds showed that sampling errors were the primary cause of station to station variability. A method for decreasing sampling errors in design wind...
TLP Fatigue Due to Second-Order Springing
For offhsore oil production in water depths beyond 300-350 m, the tension leg platform (TLP) has become an increasingly popular design concept. The TLP is a floating structure with excess...
Port of Portland's Berth 601 Floating Dock
The Port of Portland's facilities, being located on the Columbia and Willamette Rivers, are subjected to extreme water level fluctuations. Over the years, the Port has used floating docks...
