Hydroelectric Project Design Using Microcomputers
The main issue in the first stage of a hydroelectric project is to assess the influence of hydrologic parameters on design and optimum sizing of the installation and on future energy production....
Microcomputers as Productivity Aids for Small-Scale Hydroelectric Projects
Off-the-shelf software that has been used to improve productivity includes Computer-Aided-Design-and-Drafting (CADD) systems, spreadsheets, project managers, word processors, and communications...
Seismic Isolation System for a Floating Dry Dock
The seismic isolation system consists of two dolphins, each a relatively large-diameter cantilevered steel pipe pile anchored in Franciscan rock, and buffered connections to the floating...
LRFD Format for Transmission Structures
The structural design of high voltage electric transmission lines in the US is usually governed by the National Electrical Safety Code (NESC). A simple reliability-based Load and Resistance...
A Field Study of Wind-Induced Conductor Loads
A 161 kV steel pole line in Omaha, Nebraska, is instrumented to provide conductor load field data due to climatic events. Various transducers and monitoring equipment used for data acquisition...
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...
