Study of Interaction Between Pneumatic Spherical and Cylindrical Form Shells Subjected to Wind Pressure
In the design of pneumatic membrane structures, analysis of stress and deformations of structures subjected to wind is among the most important requirements. For the purpose of studying...
The Winds of Change?
In 1992, Hurricanes Andrew and Iniki combined to generate an estimated $30 billion in damage. The storms also generated their share of reports and recommendations about how best to mitigate...
Helium-3 on the Moon: Model Assumptions and Abundances
Solar-wind particles are present in the outer few 100 angstroms of each soil particle of the Moon. Of particular interest, are the volatiles hydrogen (40-100 ppm) and helium (5-45 ppm)....
In-situ Extraction of Lunar Soil Volatiles
Techniques for their recovery and utilization of the potentially valuable solar-wind elements embedded in the lunar regolith have been proposed. In order to acquire quantities of 3He...
Utilization of Liquid Carbon Dioxide for Planetary Exploration
The major component of the atmosphere of Venus and Mars is carbon dioxide CO2. This proposal is to use this carbon dioxide for planetary exploration...
Oxygen from Lunar Soil via Fluorination
This paper considers oxygen extraction from lunar soil via fluorination, for reasons of its high effectivity of oxygen release from most silicates. In addition to theoretical investigations,...
Analysis of Glass-Ceramic Production from Lunar Resources
Two simulated regoliths were used to investigate the effects of processing and composition on the properties of lunar-derived glass-ceramics. For the simulant with moderate iron concentration,...
Deepwater Waves and Tsunami Produced by the Impacts of Small Asteroids
Studies of ocean sediments may be used to determine when coastal areas have been hit by tsunamis in the past. Tsunami debris has been found to be associated with the Cretaceous-Tertiary...
Proposed Hurricane Wind Speeds for ASCE 7-95
A 2-3 second peak gust wind map has been proposed for the wind load provisions of ASCE 7-95, now in draft form. On the hurricane coast, speeds from published Monte Carlo analyses were...
Averaging Time and Maximum Speeds in Hurricanes
This paper discuses wind speed data obtained during Hurricane Andrew around Miami International Airport, at six anemometer locations which make up the wind shear warning network. Data...
Hurricane Windspeeds at Inland Locations
A critical review of the windfield and filling models used in the hurricane simulation procedure of Batts et al. [1980] clearly indicates that the hurricane windspeeds they obtained for...
The Use of Coda Waves for Characterizing the Site Effect on Strong Ground Motion
The well established separability of source, path and site effects on coda waves of local seismic events offers the most effective means for determining the site amplification factor empirically....
Criteria for Acceptable Wind-Induced Motions
This paper discusses criteria for evaluating acceptable wind-induced building motions. The paper draws on the results of moving room experiments and the performance of actual buildings...
Methods to Control Wind-Induced Building Motions
The wind-induced response of tall buildings can be controlled by global design modifications that can be placed in three broad categories, namely, design changes in structural systems,...
Damping Systems for Controlling Wind Induced Motions of Structures
This paper presents the state-of-the-art in damping systems for controlling wind induced motion of structures and their applications in the U.S. and Japan. Both passive and active systems...
Practical Application of Tuned Liquid Damper for Tall Buildings
Performance of TLD, based on the full-scale measurement of an actual tall building, is discussed in this paper. Wind induced vibration of the SYP Tower was measured during a gusty day,...
Wind Deflection Probability Analysis
A statistical analysis is performed which analyses the probability of various magnitudes of deflections of a cable-stayed roof occurring due to wind uplift. Extensive wind analyses were...
Advances in the Modelling of Long Span Bridges for Wind Effects
The continued development of longer span suspension and cable-stayed bridges has placed increased demand on both the designers and constructors of these structures for a better understanding...
Wind Effects and Countermeasures During Erection of a Cable-stayed Bridge
The cable-stayed bridge over the Karnali River in the Kingdom of Nepal was completed in 1992. Extensive wind tunnel testing indicated the likely wind response during construction. Several...
Wind Studies of the Owensboro Bridge, Kentucky
Wind tunnel studies on the Owensboro Bridge are described in this paper, including 1:50 scale sectional model tests and 1:160 scale aeroelastic model tests. Comparisons are presented and...
