An Improved Design for Grain Storage Tanks Solves Problem of Brittle Failures
The welded tank features fracture-tough steel and tube stiffeners to overcome problems evident in several failures of major tanks in recent years. Used extensively for grain storage in...
Behind the Sines, Protugal Breakwater Failure
This article highlights a report on the possible causes of failure of the massive, $178 million breakwater at Sines, Portugal. This was the largest breakwater of its kind in the world....
Cold Regions Engineering in Norway
The use of insulating materials is a key factor in cold regions engineering in Norway. It is applied in road construction in areas where frost heave and reduced bearing capacity would...
Causes and Preventions of Lamellar Tearing: Engineer's Notebook
Within the past 10 years, a steel cracking problem, lamellar tearing, has arisen after welding of thicker sections and higher-strength steels. A separation underlying a weld joining plate...
Computer-Aided Drafting in Civil Engineering
Computer aided drafting (CAD) is defined as an interactive computer graphics system suitable for the generation of engineering documentation. The development of CAD is reviewed. The computer...
Minicomputers in Structural Optimum Design
A problem dealing with the weight optimization of girders without transverse stiffeners is demonstrated. Constraints follow the 1978 AISC Specification. Actual programming is done in BASIC...
Application of Walls to Landslide Control Problems
The evolution of tieback restraint systems is presented. Case histories describe current practices for tieback design and construction and give examples of how the requirements were met...
Addressing Societal Needs of the 1980's Through Civil Engineering Research
Critical issues facing society in ten subdisciplines of civil engineering are defined and the research required to provide solutions to these issues in each area is identified. The ten...

Water Pollution Control Plant Upgraded to Meet EPA Regs
An Outstanding Civil Engineering Achievement Award Nominee, Philadelphia's Southwest Water Pollution Control Plant, has a $300 million addition which nearly doubled plant...
Denny Creek: The Toughest Bridge Washington State Ever Built
The story of how highway planners and engineers in Washington State's Department of Transportation were stopped from building a highway and viaduct through a pristine wilderness...
Structural Safety
Future building codes will go far beyond the classical emphasis on dimensioning, calculations, and specification writing. Emphasis will shift from scientific thinking to strategic thinking,...
Some Proposals for Reducing Structural Failures
Illinois is one of the few states requiring a Structural Engineer's License: a P.E. alone is not enough to practice structural engineering there. Unfortunately, even in Illinois,...
Microcomputers: Do They Have a Place in Large Engineering Firms?
During the past few years, microcomputers have really begun to take hold in small consulting engineering firms. Less well known is the fact that microcomputers are also beginning to take...
Directional Wave Spectra Applications
These collected papers and their ensuing discussions presented at the September, 1981 symposium at the University of California on directional wave spectra applications examine the present...
Bibliography on Ocean Energy
With the prospect of an increasing shortage of energy resources, there has been a growing interest in renewable alternative sources of energy. An increasing effort is being directed towards...
Steel Structures Provide Flexibility
The steel structures of several major buildings are evaluated by the structural engineers responsible for the design and construction. Included are the Park Avenue Atrium in New York;...
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,...
For Office Buildings: Long Span Concrete Slabs
A survey of 36 office buildings in the United States and Canada featuring long span concrete slabs showed concrete is a technically feasible and cost effective material for office structures....
Engineering Schools Respond to Financial Crisis
A mail survey of the 200-plus civil engineering departments at engineering schools asked each chairman for a case history of response to the financial and other crises facing the departments....
