Response of Taut Strip Models to Turbulent Wind
An experimental investigation was conducted to clarify the fundamental behaviour of the proposed taut strip wind tunnel model of long span bridge deck systems. The study shows that this...

Application of Penman Equation Wind Function
The Penman equation for computing evapotranspiration is frequently applied as the basis of irrigation system design. It has seen widespread application when sufficient data are available...

Tortional Vibration of Along-Wind Excited Structures
A method for analyzing the torsional vibration of along-wind excited structures is presented. The method is based on random vibration concepts and yields the expected maximum translational...

Aerodynamic Response of Long H-Sections
Section models of several long H-section members of the Commodore Barry Bridge were tested in wind tunnels for aerodynamic coefficients and for vibration response when supported in a three...

Aerodynamics in Air Pollution Modeling
The mechanism of pollutant transport and dispersion processes in the atmosphere is described with emphasis on aerodynamic effects due to the presence of structures, urban complex, and...

Freestream Turbulence Effects on Galloping
Galloping is the term used to describe large amplitude single degree-of-freedom motions of a structure associated with a sectional aerodynamic force characteristic which produces a force...

Windspeed Analysis of 1977 Birmingham Tornado
A set of postmortem force-response type analyses have been conducted and windspeeds quantified for the April 4, 1977, North Birmingham, Ala. tornado. Immediate field damage surveys and...

Energy Conservation Through Improved Aerodynamics

Five Millions Square Foot Tent Roof
Saudi Arabia will soon be the site of the world's biggest roof. Consisting of a seris of modules, each overing 10.5 acres, the roof is made of tentlike fabric squares supported...

Deterministic Torsional Building Response to Winds
The dynamic response of tall buildings to wind loads, including the torsional degree-of-freedom, is investigated using a sinusoidal pseudo-turbulent representation of atmospheric gusts...

Active Turbulence Generator for Study of Bridge Aerodynamics

Effect of Free-Stream Turbulence on Drag of Bluff Bodies

Natural Frequencies of Axially Loaded Bridge Members
The purpose of this paper is to present some formulas that can be used to check the aerodynamic stability of the more typical bridge members having two axes of symmetry. The principal...

Free Fall of Large Pipes
The design of nuclear plant facilities to withstand the effects of tornadoes has required estimates of the motion of objects accelerated in a tornado windfield. This has inspired investigations...
