Pyrites Hydroelectric Project, Canton, New York
This paper describes the Pyrites Hydroelectric Project in Canton, New York, an 8-MW project completed in December 1985. The key to its successful development was a team approach that included...
Sinkhole Rectification by Compaction Grouting
The unraveling of the overburden by solution activity in karst formations has caused many problems in existing structures and has generated high foundation costs on new construction. Slurry...
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,...
Probabilistic Load Combinations in Nuclear Structures
A variety of loads affect a nuclear power facility during its lifetime. The magnitudes or intensities of these loads are uncertain, and for some of them, their time of occurrence is also...
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...
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...
Bayesian Updating of Seismic Fragilities of Nuclear Power Plant Components
Seismic fragility is represented by a curve of the conditiional probability of failure as a function of the peak ground acceleration. Since there are many uncertainties in the model and...
Revising a Reservoir Rule Curve for Multiple Uses
The Jackson Hydroelectric Project generates power, supplies municipal water, provides flood control, maintains anadromous fishery minimum instream flows and studies various reservoir rule...
Risk Management for Water Supplies During Droughts
This paper describes a method for deriving policies for the operation of public water supplies under impending and actual drought conditions. Unlike previous models based on optimization...
Alternating Direction Oxidation Ditches?A Cost Saving Technology from Denmark
A soon to be released EPA report claims that in Denmark, small alternating direction oxidation ditches (ADOD) save as much as 70% of the cost for conventional oxidation ditches. The alternating...
Reef Breakwater Response to Wave Attack
A method of predicting stability of a class of low-crested rubble mounds referred to as reef breakwaters is presented. Findings are based on a study which included an extensive series...
Water Power '87
The 1980's have been characterized as an era of uncertainty for world energy including future demand for energy, fuel prices and availability, regulatory constraints, environmental...
A Study in Nuclear Decommissioning
The Gentilly-1 nuclear power plant two year decommissioning project launched a series of firsts for the nuclear power industry. It was the first commercial sized plant in the world to...
Corrosion Monitoring of Critical Service Pipelines
Corrosion, including microbiologically influenced corrosion (MIC), is receiving much attention as a significant piping material performance concern particularly for critical service pipelines...
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...
Design for Variable Frequency Drive Applications
This paper presents fundamental design criteria used to evaluate the operational and economic feasibility of installing a variable frequency drive (VFD) on a petroleum products pipeline....
