Pressures on Prisms in Turbulent Shear Flows
Experimental results are presented which show that Melbourne's 'Small Scale Spectral Density Parameter,' S, controls the negative pressures on the...
Dynamic Response of Tall Buildings to Wind Loads
The purpose of this study is to perform a probabilistic analysis of tall buildings subjected to wind excitation. A time domain simulation is first applied to the nonlinear problem. After...
Effect of Air Gap on Platform Reliability
A simplified reliability study of the effect of lateral wave forces impacting the deck of a fixed platform is presented. The reliability of the deck legs, considered the primary resistance...
Pipe Geometry and Pipeline Bridge Wind Oscillation
Static and modal analyses of two pipeline suspension bridges owned by American Natural Resources - the Patterson Loop Aerial Crossing (PLAC) with a span of 850 feet (259 meters) and the...
Cables in Trouble
Having inspected more than half of the world's cable stayed bridges, the authors conclude that many are in danger of sudden collapse unless corrosion problems can be stopped....
Japan Spans the Inland
Japan recently opened the Kojima-Sakaide Route, a 13.1 km series of bridges across the Inland Sea. The route connects two of Japan's four main islands�Honshu and Shikoku....
Cable Stayed Bridges
Two of these five papers on cable-stayed bridges deal with wind analysis. One develops the theory for motion due to flutter and reaches the conclusion that the vibrations are, in general,...
Arctic Coastal Processes and Slope Protection Design
Cold regions present special challenges for civil engineers. The papers in this book address arctic coastal processes and slope protection design. The first part of the book focuses on...
Use of the Penman Equation in Inter-Mountain Valleys
H.L. Penman equation as well as the J.L. Monteith version of this equation were compared under the advective conditions of the Grand Valley of Colorado. The wind function in the general...
Coastal Flood Insurance Study Procedures for Puget Sound
Procedures for a coastal flood insurance study are presented. The 10-, 50-, 100-, and 500-year recurrence interval runup flood evaluations are estimated from an analysis of historical...
Overview o New England Coastal Flood Study Methodology
This paper presents an overview of the development of methologies used to determine the probabilistic flood levels for New England coastal flood insurance studies. The Federal Insurance...
Modelling the Effects of Wind on Pavement Runoff
Phase I of this study, the primary focus of this paper, consists of the development of a mathematical model to predict runoff depths from a pavement under uniform wind conditions. The...
Hydrodynamic Response of an Estuary to Storm Forcing
Previous work on the response/sensitivity of an estuarine hydrodynamic model to the choice of model parameters is extended to include a preliminary consideration of wind-generated waves....
Surgery in the Microgravity Environment
As man becomes more active in space, the possibility of major medical emergencies requiring surgical procedures will increase. Surgery in the microgravity environment involves many challenges...
Solutions to Space Station Designs
Any space station that is to be designed for extended human use may require gravity. The artificial gravity field required can be produced by rotating the structure. As the Soviets have...
Instant Landmark
The 42 story curved glass facade of an $80 million structure at 17 State St. is destined to appear on the New York City postcards that show the tip of Manhattan Island. The site offers...
A Safe Skyscraper For the Seismic City
When completed in late 1989, the 73-story First International World Center will be the tallest office building in Los Angeles. The steel structure of the building was designed to be ductile...
Journal of Aerospace Engineering
The Journal of Aerospace Engineering promotes the implementation and development of space and aerospace technologies and their transfer to other civil engineering applications. Topics of interest include...
Cause and Elimination of the Deflation Zones Along the Atlantic City (New Jersey) Shoreline
After recent construction of several large hotels and apartment buildings directly fronting the Atlantic City boardwalk, large blowouts were observed to occur during the winter season...
U.S. Coast Guard Experience with Wave Turbines
Since 1980 the United States Coast Guard has been developing a lighted buoy for exposed areas and congested harbor entrances. The buoy hardware is of conventional design while the signal...
