Development of a High Resolution Spectrometer for Measuring the Near-Earth RFI Environment: The First Auto-Correlator in Space
A detailed description of the near-Earth RFI (radio frequency interference environment in the 0.5 - 16.5 MHz range is required before low frequency arrays can be designed and implemented...

The History and Present Status of Microwave Aircraft
The history of microwave-powered aircraft is reviewed from the point of view of interaction between the technology of beamed microwave power transmission and the applications for it. the...

Cables Over the Mississippi
As the designer of the Great River Bridge over the Mississippi between Gulfport, Ill. and Burlington, Iowa, Sverdrup Corp., St. Louis, had to find a way to connect the new five-lane crossing...

A Dome For the 21st Century
Putting a circular dome on a square building--the classical architectural design challenge--takes on new proportions at the Federal Building and Courthouse in Charleston, W. Va. The 170...

Preserve and Protect
Historic and landmark structures constructed of unreinforced masonry and stone are among the most vulnerable to strong ground shaking and are often subject to possible collapse. For the...

Design of Mat Foundation for Egg Shape Digesters
Two levels of ground motion, the Maximum Probable Earthquake and the Maximum Credible Earthquake, were considered in designing the 2.5 million gallon egg shape digesters and their combined...

Concrete Buildings in Regions of High Seismicity
Structural systems for multistory concrete buildings in regions of high seismicity are reviewed. The suitability and certain practical aspects of the systems are discussed. A Uniform Building...

Seismic Design of RC Structural Walls with Unsymmetrical Cross-Sections
An overview of seismic design issues and current experimental research for walls with unsymmetrical cross-sections is presented. The experimental studies include approximately 1/4 and...

Coupling Translation and Rocking Motions
In the design of concrete block foundations for rotating and reciprocating machines, it is important to avoid resonant conditions. Therefore, accurate determination of the frequencies...

This paper discusses the differences of seismic responses of bridges among various analysis methods and approaches....

Dynamic Loading of a Rigid Frame Bridge
The objective of this paper is to investigate the dynamic response of a rigid frame bridge to two trucks (side by side) passing over the rough bridge deck. The rigid frame bridge is designed...

Bridge Rail Impact Forcing Functions
Bridge rails are designed according to AASHTO standards with a static 10-kip (44.5 kN) lateral load. The computer programs BARRIER VII and COSMOS are used to determine the deflections...

U.S. / Japan Large Scale Cooperative Research Program for Steel Structures
The US/Japan Cooperative Research Program Utilizing Large Scale Test Facilities for Earthquake Resistant Design was initiated in 1980 using a combination of full-scale, small-scale, subassemblage...

Representation and Processing of Design Standards: a Bifurcation between Research and Practice
There have been attempts to develop representations of design standards and procedures for computing representations of the design standard on which computations are based. However, within...

First Bank Place: A Composite Cruciform Spine
The First Bank Place, designed by the internationally known architectural firm of Pei Cobb Freed and Partners, is a granite-clad, 56 stories tall building in downtown Minneapolis. Presented...

Composite Walls as Shear Elements in Tall Structures
This paper describes a system of composite walling that can be used as a lateral load resisting system in tall structures. The composite walling comprises two skins of profiled steel sheeting...
