At Four Western Stadiums, Wood Comes Out on Top
In recent years, several long-span timber roofs have been constructed atop large arenas and stadiums in the Western states. The choice of glued-laminated timber offers designers good economy,...

Replacing Corroded Cables on a Cable-Stayed Bridge
The cable-stayed bridge across Venezuela's Lake Maracaibo is among the longest bridges of its type. But after years of service, corroded cables threatened to snap, which would...

Slope Stability Program
This article includes an entire computer program, written in BASIC computer language. The program is a simplified version of programs which have been written for large computer systems....

GAO Finds Massive Failure of Wastewater Treatment Plants
A year-long study by the General Accounting Office of 242 wastewater treatment plants in 10 states concluded that discharge permit violations are the norm, not the exception. The failures,...

Management Keys: Freedom to Create, Responsibility for Failure
Management policies for inventors and engineers are reviewed in this interview with Professor Dan Pletta, University Distinguished Professor of Engineering at Virginia Polytechnic Institute...

Geotechnical Research Needs
A National Science Foundation-ASCE workshop on research needs looked at, among other subfields, geotechnical engineering. The study identified a number of research needs�based on society's...

Structural Plastics for the 80s
Engineers in non-civil fields have been using more and more light-weight, high-strength structural plastics and plastic composites every year, but civil engineers have barely begun to...

Structural Failures
A relatively few, spectacular failures of new buildings have caught the public attention. Despite the publicity, the track record of structural designers is generally outstanding. Nevertheless,...

Stop the World-- I Want to Get Off!
The essays that won first and third prizes in the 1981 Essay Contest are presented. The first-prize essay, by John Huston, is entitled Stop the world�� I want to get off. It is a satire...

Long Span Roof Structures
The papers included in these proceedings treat a wide range of technical topics related to long span roof structures including new structural concepts, structural stability, the effects...

Roof Design: Avoid Ponding by Sloping to Drain
Roofing contractors recommend that roofs possess enough slope to permit complete drainage within 48 hours of rainfall. Otherwise ponds will form which can cause leakage and even contribute...

West Virginia Cooling Tower Collapse Caused by Premature Form Removal
The collapse of a reinforced concrete cooling tower under construction at Willow Island, W.Va. in April 1978 resulted in 51 fatalities, making it the worst construction accident in American...

Hartford Coliseum Roof Collapse: Structural Collapse Sequence and Lessons Learned
As with all structural failures, the collapse of the Hartford Civic Center Coliseum roof has raised many questions about design and analysis procedures. The profession should learn from...

Research Needs in Hydraulics, Coastal Engineering and Irrigation
Last June an ASCE/NSF team gathered at Warrenton, Va., to prioritize research needs in civil engineering. They split the field into 10 subcategories, one of which is Hydraulics, Coastal...

Basics in Failure Analysis of Large Structures
Failure analysis procedures can usually determine the most probalbe cause of a structural failure. Then it is possible to determine why the initial design, materials selection, and fabrication...

Notched Trusses Give Low-Cost Conversion of Hangars for Jumbo Jets
Physically notching the structural members in a hangar roof solved the problem of moving new DC-10 aircraft into and out of maintenance hangars built for smaller, earlier-generation commercial...

Part Two: Basics in Failure Analysis of Large Structures
Part two of a article, with part one appearing in May, 1980. Part two begins with microscopic examination which includes the use of scanning and transmission electron microscopes. Covers...

Reducing Failures During Earthquakes
There are common building design and structural errors that result in unnecessary building failures during earthquakes. The failures are the result of design errors, changes and economies...

The Fabric Roof
Only six years after the opening of the first fabric-roofed building, fabric structures are being used all over the world in applications undreamed of only a decade ago. The article recounts...
