Micro-Computer Program: Roof Purlin Design
A micro-computer program is explained in step-by-step manner as a shortcut for biaxial bending design with results in as little as 60 seconds. Biaxial bending requires the consideration...
The Booming Business in Wick Drains
Prefabricated vertical wick drains, used to improve weak, saturated soils, have been used in Japan and Europe for 20 years but were introduced in the U.S. only four years ago. Since then...
Failure of the Breakwater at Port Sines, Portugal
The objectives of the Port Sines Investigation Panel were to collect perishable data on and to identify causes of the failure on February 26, 1978, of the rubble mound breakwater at Port...
Grouting in Geotechnical Engineering
The 63 pages included in these proceedings came from 12 different countries and deal with the pertinent advances in grouting materials and technology that have occurred throughout the...
Application of Plasticity and Generalized Stress-strain in Geotechnical Engineering
This volume on the application of plasticity and generalized stress-strain in geotechnical engineering is divided into two main sections, with an introduction on soil constitutive model...
Construction Equipment & Techniques for the Eighties
Thirty-three papers on construction equipment and techniques are presented. Construction equipment management is discussed, including criteria for equipment selection, utilization and...
Engineering and Construction in Tropical and Residual Soils
Thirty-one papers and six invited lectures presented at the specialty conference on engineering and construction in tropical and residual soils are included. The proceedings represent...
Preventing Another Sunshine Skyway Bridge Disaster
America will not soon forget the tragic collapse of the Sunshine Skyway Bridge into Tampa Bay almost two years ago. That accident was a costly lesson in the crucial importance of protecting...
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...
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...
Olmos Dam Modifications
(
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,...
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...
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;...
