Rehabilitation of Vertical Thin-Walled Breakwater
Physical hydraulic model tests were conducted to measure wave transmission and force characteristics of a partial vertical thin-walled breakwater. Tests were run for the breakwater in...
Effects of Hydroelectric Turbine Passage on Fish Early Life Stages
Turbine-passage mortality has been studied extensively for juveniles and adults of migratory fish species, but few studies have directly quantified mortality of fish eggs and larvae. An...
Wind Generated Wave Resuspension of Sediment in Old Tampa Bay, Florida
Vertical profiles of velocity and suspended-solids concentration were measured at a scientific instrumentation platform in Old Tampa Bay during the passage of a cold front in March 1990....
Preventing Stilling Basin Abrasion
A 1:10 scale physical hydraulic model of Taylor Draw Dam outlet works was used to develop modifications to prevent back flow intake of rock into the stilling basin. Much of the back flow...
Partnering Benefits?A Headquarters Department of the Army Perspective
Army facilities make a statement by reinforcing and reflecting Army values. High quality facilities attract, motivate, and retain quality personnel vital to national defense. As defense...
The Enhancement of Air-Sea Gas Exchange by Oceanic Whitecapping
The hypothesis that oceanic whitecaps and the accompanying buoyant bubble plumes greatly enhance the air-sea transfer coefficient of gases subject to liquid phase control has recently...
Parameterization of Air-Ocean Gas Transfer
A renewal-type model, based on the physics of a molecular sublayer, allows the derivation of parameters to describe air-ocean gas transfer and the temperature difference across the cold...
Specification for the Design of Cold-Formed Stainless Steel Structural Members
ASCE's standard
Guide to the Use of the Wind Load Provisions of ASCE 7-88 (formerly ANSI A58.1)

Probabilistic Assessment of Wind Loading For Structural Analysis
Records of extreme annual gust velocities from 11 weather stations in central-southern Brazil, classified according to orientation (octants) and type of storm (TS and EPS winds), result...
Wind-Induced Response of Torsionally Coupled Buildings
This paper summarizes the results of a comprehensive three-dimensional dynamic analysis of tall buildings subjected to fluctuating wind forces. Random vibration theory is used to relate...
Reliability Analysis in Estimating Turbulent Wind Force on Offshore Structures
This paper presents the results of a reliability analysis carried out to estimate low frequency turbulent wind drag force (including extreme values) acting on a floating offshore structure....
Loading Uncertainties in Extreme Waves
Uncertainties associated with extreme base shear forces and extreme overturning moments are estimated for an idealized eight-legged jacket platform. The structure is assumed to respond...
Stochastic Evaluation of Landing Pier Construction
This paper discusses the process of determining the magnitude of external force such as wind and wave pressure exerted on marine structures under construction, and the learning curve of...
Probabilistic Evaluation of the Performance of Axially Loaded Bored Piles
Probabilistic evaluation of single slender elastic elements, bored piles, in a multi-layered soil system without noticeable displacement of the soils are considered. The numerical analyses...
A Continuous Damage Index for Seismic Reliability Assessment of Structural Steel Elements
Based on experimental investigations using steel plate elements subjected to cyclic axial loading, a continuous damage and/or deteriorating process is examined. In order to describe intermediate...
Fluid Behavior Considerations for Waste Management in Low-Gravity Environments
Design of waste recycling systems for spacecraft requires a knowledge of fluid behavior in microgravity. As gravity is reduced, phenomena usually ignored in the One-G environment of earth...
Artificial Gravity Research Facility Options
On a long duration manned mission to Mars, the physiological changes caused by microgravity may be counteracted by artificial gravity. This paper evaluates several different classes of...
Artificial Gravity: Human Factors Design Requirements
A major challenge of manned spaceflight is to assure the health, well-being and performance of the space inhabitants. As man ventures beyond Earth's orbit to settle the Moon,...
Partial Gravity: Human Impacts on Facility Design
Partial gravity affects the body differently than earth gravity and microgravity environments. The main difference from earth gravity is human locomotion; while the main difference from...
