This state-of-the-art report presents fundamental and practical aspects of modern wind engineering practice as it relates to structural design. The first chapter includes information on...

Collapse Analysis of RC Shells Based on a New Fracture Criterion

In-Situ Testing to Characterize Electric Transmission Line Routes
A review of the literature has shown few definitive studies which separate test variability from soil inhomogeneity. A sensitivity study was performed to evaluate the effects of the overall...

Use of Nondestructive Testing in Rehabilitation of Wood Cooling Towers
State-of-the-art nondestructive evaluation (NDE) techniques, destructive testing, structural analysis, degradation rate models and statistical analysis are combined to optimize a major...

Design Criteria for Generators in Low-Head Hydro-Power Plants
Principal characteristics and design features of such generators are discussed and options and preferences in their selection mentioned. Effects on inertia constant, efficiency, reactive...

Lattice Tower Design Using Cold-Formed Shapes
The use of cold-formed shapes in lieu of hot-rolled angles may lead to major changes in the design of lattice transmission towers. The design procedure of the new shapes is more creative,...

Cold-Formed Angles for Transmission Towers
Cold-formed members enable the engineer to design transmission towers that may be more cost-effective than those built with hot-rolled angles. Members can be designed to closely fit the...

Design and Test of Cold Formed Steel Members
Latticed systems represent the most spread and low-cost solution for electrical trasmission towers, when ground conditions do not affect the design choice. Steel angles have been used...

Bolted Connections for Steel Towers
Laced electrical transmission towers require on-site assembly. Consequently, the number of bolts and pieces are important considerations in the total cost of the structures. ASTM A394(1)...

The Response of Transmission Towers in Hilly Terrain to Typhoon Winds

Modeling the Fate and Transport of Biocides in Estuarine Power Plant Cooling Water Discharges
This paper presents a framework with examples for understanding the fate and transport of cooling system discharges into estuaries through the use of modeling. The modeling of biofouling...

Tapping Deep Water Resources
Lena is the first commercial guyed tower. Its jacket is the longest ever fabricated, loaded out and launched in one piece. Lena stands in 1,000 ft deep water and has a three-level oil...

Hydrothermal Model Study of Stratified Flow in a Power Plant Cooling Water Recycle/Intake Canal: Reynolds and Densimetric Froude Number Effects
During the winter of 1983-1984, the control of frazil ice at the trash tracks using pneumatic air guns was evaluated at Danskammer Point Generating Station. This paper presents a brief...

Laboratory Studies for the J. H. Campbell, Unit No. 3, Cooling Water Intake Design
A three-year study sponsored by the Empire State Electric Energy Research Corporation was conducted to determine the overall efficiency of a full-scale angled screen demonstration facility...

Make-up and Blowdown of a Cooling Pond
A mathematical model was developed to simulate the operation of a recirculating cooling pond for a planned nuclear power plant in the Midwest. The objective of the pond operation is to...

Analysis of Resonance in Pressurized Piping Systems Via a Microcomputer
In this paper a digital simulation technique for the analysis of resonance is presented that is appropriate for microcomputer applications. The model utilizes the transfer matrix method...

Transmission Tower Foundations in Weathered Rock
A case history is presented which discusses the siting, design and construction of the tower foundations for a transmission line in southwest Alaska. The project, completed in 1983, consists...

Probabilistic Wind Response of Cooling Tower Using Monte-Carlo Simulation

Intermountain Power Project Seismic Design
Coal-fueled generation units of the Intermountain Power Project are constructed in a seismically active area of Utah (UBC Zone 3). The seismic design criteria were published during the...
