The analysis and design of a given hyperbolic cooling tower for a nuclear power plant are reviewed. Analysis is performed using available computer programs. Various loading conditions...

Dynamics of Guyed Towers
The free vibration of a guyed tower has been analyzed taking into account the effect of the masses of the guys. Linearized differential equations of motion were derived for a guyed tower...

Power Plant Cooling Systems
Types of systems now available and proposed with data required from other than engineering sources to insure compliance with environmental regulations covering both nuclear and fossil-fueled...

Differential Settlement of Hyperbolic Cooling Towers
A differential displacement of the supporting system of a hyperbolic cooling tower is modeled by a five column segment of the shell base. An explicit relationship between the relative...

Guide for the Design of Aluminum Transmission Towers
The Task Committee on Lightweight Alloys has prepared this guide for the design of transmission towers. The Executive Committee of the Structural Division decided that no specification...

Free Vibration of Hyperbolic Cooling Towers
A modified finite difference technique is used to determine the natural frequencies and mode shapes of hyperbolic cooling tower shells. The influence of the meridional curvature and the...

EHV-DC System Ties Los Angeles to Northwest
Extra-high-voltage direct-current (EHV-DC) power transmission is competitive with extra-high-voltage, alternating-current (EHV) transmission for transporting bulk power over long distances....

Power Plant Cycles for Dry Cooling Towers
The use of dry cooling towers with air as the cooling medium will become more prevalent in the not-too-distant future as water quantities available for consumption in evaporative cooling...

Water Consumption Study for Navajo Plant
As suitable sites for very large steam-electric generating plants along natural waterways become scarcer, the use of cooling towers for purposes of cooling plant waste heat will increase....

Computation of Cutting Lengths of Guys
A method is presented for computing the cutting lengths of cable segments used as guys for antennas and transmission towers. The analysis takes into account both concentrated and distributed...

Computer's Role in Transmission Line Design
This paper is based on the experiences gained in the development and use of computer techniques in the design of transmission lines. The computer acts as a catalyst providing the facility...

Tower: Design System for Guyed Towers
TOWER consists of a package of analysis routines that are manipulated by the use of a problem-oriented language. The system has been specifically designed for remote terminal, time-sharing...

Earthquake Design Formula Considering Local Soil Conditions
A new earthquake code formula is proposed, based on the principles of the response spectrum technique considering the local soil conditions. Six different groups of soil are defined from...

Simulation of Ammonia Stripping from Wastewater
A computer program that can be used for the design and simulation of ammonia stripping and film packed cooling towers is described. The ammonia stripping portion of the program is embedded...

Guide for Design of Steel Transmission Towers
The purpose of this report, Guide for Design of Steel Transmission Towers, is to provide a basis for the structural design of self-supporting...

TOWER: A Design System for Guyed Towers

Stability of Hyperboloidal Cooling Tower
An infinitesimal theory of instability of an elastic orthotropic shell of revolution subjected to uniform external normal pressure is developed. The theory leads to a linear eigenvalue...

Hyperbolic Cooling Towers, Development and Practice
The development and practice of hyperbolic reinforced concrete cooling towers are described. The collapse of three large towers in England caused concern and it initiated research in this...

Waste Heat Disposal from Power Generating Stations
Steam-electric plants, nuclear of fossil fueled, are expected to provide the bulk of the growing needs for electric energy. As part of the operating cycle, such plants require large flows...

Portage Mountain Intake Structure and Facilities
Portage Mountain Project, 600-ft high earth dam creates a reservoir of 57,000,000 acre-ft. The free standing water intake towers rise 115 ft above the rocks to support the bridge. For...
