Response of Concrete Buildings to Lateral Forces
ACI-ASCE Committee 442 (Response of Concrete Buildings to Lateral Forces) has just issued its report (ACI-ASCE 442 1988a). In that Report, the performance of reinforced concrete buildings...
An Analytical Synoptic-Dynamic Study About the Severe Weather Event Over the City of Rio De Janeiro on January 2, 1987
The paper reviews the synoptic parameters that lead to the severe weather occurred on January 2, 1987 over the city of Rio de Janeiro. The pattern of this weather was reported on the newspapers...
Structural Design, Analysis and Testing
This volume contains the papers presented in 21 sessions of the 1989 Structures Congress held in San Francisco. The papers cover a wide range of topics including types of construction...
Use of POE/POU Technology at US Army Installations
A wide spectrum of adverse water quality characteristics has been experienced at US Army installations throughout the country. These characteristics, both interim and long-term in nature,...
Erosion and Sedimentation Research in ARS
The paper presents a brief history of the growth of the erosion and sedimentation research program in the Agricultural Research Service of the U.S. Department of Agriculture. Subjects...
Vessel Induced Physical Effects in a Navigation Channel
The U.S. Army Corps of Engineers is investigating ways to improve lockage efficiency at the Marmet Locks on the Kanawha River, West Virginia. A physical effects prediction model have been...
An Investigation of a Pumped Storage Hydropower System
In order to provide a realistic basis of determining the viability of a wind-powered hydroelectric system at a potential site, an evaluation technique has been developed. Basically, this...
Analysis of Concrete Gravity Dams Using Microcomputers
Monenco Consultants Limited has developed a microcomputer program entitled 'DS2' for the stability analysis of concrete gravity dams. This paper discusses this...
Assessing Site Assessments
Laier and Sibley contend that the growth in environmental site assessments, fast becoming routine in many types of real estate transactions, could create a windfall market for engineering...
New Roof for an Aging Temporary
The wartime temporary design of a 1942 industrial building justified use of green timber for its roof trusses and higher than usual allowable design stresses. Some 45 years later, a new...
Simulation for Construction Planning and Control
A prototype system was created as part of a research project for the U.S. Navy Construction Battalions (the Seabees) and has been given the acronym SEACONS (SEAbee Construction Simulation)....
Variable Speed Generators in Hydro Applications
This paper discusses the investigation of the doubly-fed variable speed machine as a potential candidate to convert a varying input speed to a constant frequency, constant voltage output....
Characteristics of the Roesel Machine Used for Small Scale Hydro/Wind or Sea Wave Electric Power Generation and Storage
An electrical machine with property of synchronous as well as asynchronous characteristics and based on ceramic magnet programming technology by continuous printing of the desired number...
Controlled Yielding of the Lateral Boundaries of Soil Retaining Structures
Lateral expansion of conventional or reinforced soil backfills is necessary to establish and maintain the minimum lateral stresses on soil retaining structures. Laboratory studies are...
On the Post-Flutter State of Cable-Stayed Bridges
This paper deals with the post-flutter vibrations of cable-stayed bridges. An approximate theory and an approximate analytical solution method have been established. A numerical example,...
Effect of Spatial Variation of Ground Motions on Bridges
The effect of spatial variation of ground motions on the response of a two-span bridge is presented. Perfectly and partially correlated earthquake ground motions are used as input motions...
Time Series Analysis of Wind Pressures on Low Buildings
A new methodology for the description of local wind pressures on the building envelope of mono-sloped roof buildings by using time series analysis is described. A simple AR(1) model has...
Design Wind Loads for Broadcasting Antennas from Short Time Records
Very useful would be procedures for the determination of the design wind load on the basis of short time records, of duration comparable with the preliminary and/or design phases, so that...
On Modelling the Nonlinear Relationship Between Random Fields by Means of Higher-Order Spectra
This paper addresses the input-output relationship of nonlinear systems that may be expressed in terms of a hierarchy of linear, quadratic and higher-order transfer functions or corresponding...
Stochastic Properties of Wind Spectra
In the first part of this paper the correlation function of measured wind spectra is compared with theoretical correlation models assuming a stationary wind process. This comparison indicates...
