Summary of the Effects of the 1985 Mexico Earthquake to Power and Industrial Facilities
A major industrial area and two power plants are near the epicenter of the Magnitude 8. 1 Mexico Earthquake of September 19, 1985. All investigated facilities are modern, generally well...
Seismic Rehabilitation: Why, When and How
Common methods of seismic rehabilitation are: repair of cracks, reconstruction of structural elements, addition of stiffening elements, and addition of dampers. A major consideration is...
Thoughts on a Different Approach to Seismic Design Codes
The aim of this paper is to show that some of the principles on which conventional structural design is based are not directly applicable to seismic design. Seismic design, and the corresponding...
Bridge Design By 1-2-3
MULTBEAM, a Lotus 1-2-3 template, can be used to analyze simple-span, multigirder steel highway bridge superstructures. Since it was developed for in house use by Sverdrup Corp., this...
The Road to Drained Pavements
In California, a fast-draining base course within the pavement structure is now the preferred design. For the first time, the 1987 edition of the California Highway Design Manual recommends...
Transmission Structure Foundation Loads and Performance
Transmission line structures are subjected to unique loading conditions which for the majority of structures results in maximum loads which occur infrequently and act for only short periods...
Construction and Design of Foundations for French Overhead Power Transmission Network
This paper summarizes present conception and design of foundations for 90 to 400 kV overhead lines in France. Firstly principles of geotechnical studies in use are presented: various types...
High Capacity Multi-Helix Screw Anchors for Transmission Line Foundations
Three case history summaries are presented which discuss the siting, design, and construction of towers supported on multi-helix screw anchor foundations in the Virginia Power service...
Design of Drilled Piers in the Atlantic Piedmont
