Wind Cross-Spectrum Effects on Long-Span Bridges
This paper discusses current analysis for long span bridge response based on wind components. The authors summarize the development of techniques which take such components into account,...
Taylor-Galerkin Method for Wind Wave Propagation
Recently Taylor-Galerkin method has been used to successfully solve advection-dominated flow problems. This method performs quite well in reducing numerical dissipation and numerical dispersion...
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...
Computation of Wind Pressures on L-Shaped Buildings
The paper refers to the numerical simulation of turbulent wind conditions around an arbitrarily-shaped building composed of two rectangular blocks. The time-averaged Navier-Stokes equations...
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...
Finite Element Large Deflection Analysis of Cylindrical Shells with Different Types of Cutouts
Nonlinear finite element is used to find the elastic buckling load and the maximum deflection for cylindrical shells subjected to unsymmetrical pressures due to wind. These shells are...
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...
In-situ Release of Solar Wind Gases from Lunar Soil
A concept is described which has the potential to perform the in-situ heating of the lunar regolith in order to release the solar wind gases. The poor thermal conductivity of the lunar...
Isotopic Separation of ?He/4He From Solar Wind Gases Evolved from the Lunar Regolith
The potential benefits of 3He when utilized in a nuclear fusion reactor to provide clean, safe electricity in the 21st century for the world's inhabitants...
A Mars 1 Watt Vortex Wind Energy Machine
Ever since Viking I and II landed on the surface of Mars in the summer of 1976, man has yearned to go back. But before man sets foot upon the surface of Mars, unmanned missions such as...
Very Low Frequency Radio Astronomy from Lunar Orbit
This paper discusses the use of very low frequency aperture synthesis as a probe of astrophysical phenomena. Specifically, the science achievable with the Lunar Observer Radio Astronomy...
A Novel University-Industry-Government Partnership
The Ohio Aerospace Institute (OAI) is a Consortium of nine universities in Ohio, the NASA Lewis Research Center (LeRC) in Cleveland, the Wright Laboratory (WL) at the Wright Patterson...
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...
Nowcast Protocol for the Great Lakes Forecasting System
The Great Lakes Forecasting System is a cooperative federal-university undertaking designed to implement a predictive system for each of the Great Lakes. The desired forecasts concentrate...
A Coastal-Ocean Hindcast/Forecast Model
Flows in the coastal oceans are produced by interactions of different components: tides, winds, buoyancy discharge from estuaries, topography and remote forcing of deeper-ocean origin....
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...
Modeling Tidal and Wind Driven Circulation in Sarasota and Tampa Bay
As part of an effort to quantify the effects of hydrodynamics on water quality within Sarasota Bay, Tampa Bay and their adjoining waters, a field and modeling study of circulation and...
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...
