Changing Attitudes Towards Elevated Structures
This paper examines the reaction of professionals and politicians to specific examples of proposals for new public transport systems that entail elevated structures in central areas. When...

Use of Computer Graphics in the Analysis of Large Space Structures
This paper illustrates how interactive computer graphics can provide a useful tool in setting up analytical models of structural latticeworks comprised of large numbers of degrees of freedom...

A Space Frame Forecast
New York City's Jacob K. Javits Convention Center has the largest space frame of its kind in the world. There are several unique design features in the space frame, among...

The Practitioner's Approach to Infrastructure Master Planning: The State of the Art
Infrastructure master planning is still a disjointed practice, but recent empirical work provides a base from which coordinated efforts, tying together the various sectors, are possible....

High Tech Is More Than a Look
Hollow steel section, also known as tubular steel, is being used for its clean dramatic look, its structural efficiency in compression, the economic efficiency of combining structure and...

Underground
The Civil and Mineral Engineering Building at the University of Minnesota in Minneapolis was designed with careful attention to the environment. In the years ahead, this building will...

Frame Program
A plane frame program for structural analysis that is short to program and easy to understand is presented. Included inl article is a complete print-out of the program with a step-by-step...

Compression Rings Support Deep Cut
The plans for building the Cuyahoga Valley Interceptor Lift Station in Cleveland, Ohio, called for 126 ft. (38.4 m) by 105 ft. (32 m) construction, some 80 ft. (24.4 m) below grade. Bracing...

Big New Radio Telescope Array Listens in on Space
The world's most powerful radio telescope is so sensitive that it can detect a small CB rig operating on a distant planet. The Very Large Array (VLA) Radio Telescope Facility...

Building Rehabilitation: The Last Resort
Rehabilitation of buildings often seems initially cheaper than new construction, but the hidden costs of renovation are making many builders prefer new structures. The advantages of new...

In modifying the decade-old Apollo man-to-the-moon launch facilities at Cape Kennedy, FL, for the forthcoming Space Shuttle mission NASA and contractors made two major innovations: To...

Space: A Place to Work
An overview of the nation's space program as space shuttle capability nears reality. The cargo truck aspects of the shuttle will transform our efforts in space. In the near...

Building Skyscrapers in Orbit
NASA plans to build a host of large structures (communications antennas, remote-sensing radiometers, solar power satellites, etc.) in space. Three ways to build them are: (1)Fabricate...

Facelifting City Streets
Augusta, Georgia rebuilt a four-block, 10-acre section of the main street (Broad Street) to improve traffic flow, beautify the street, provide safe, efficient and convenient parking and...

Intermediate Service Levels in Water Distribution
This paper is concerned with design standards for secondary water distribution networks. Based on field studies in the Middle East and Africa, mathematical equations were developed for...

Chevrolet Raises the Roof
Chevrolet's Gear and Axle plants in Detroit needed more space so a decision to renovate the 60-yr old structures rather than relocate the operation was made. New roof structures...
