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...
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...
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...
Engineer's Notebook: One-step Formula for R/C Tension Steel
In the design of reinforced concrete beams, after loadings and materials are defined, the first step is to assume a beam depth. Then the required steel area and beam width are determined....
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...
World's First All-Rollcrete Dam
Willow Creek Dam in Oregon will be the world's first concrete gravity dam designed specifically for and exclusively by roller compaction methods. The average in-place cost...
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....
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...
Fiber-Reinforced Concrete Proves Worth for Airport Pavements
Laboratory and field tests indicate that fiber-reinforced concrete has higher flexural and tensile strength, higher impact resistance, and improved resistance to spalling and joint deterioration...
Steel Cable-Stayed Bridges: Can They Compete in the U.S.?
During the past decade, concrete bridge designs have been winning more bids for contracts than steel cable-stayed bridges. Reasons for this trend are examined. A brief evolution of bridge...
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...
State-of-the-Art Report on Finite Element Analysis of Reinforced Concrete
This comprehensive state-of-the-art report contains a summary of the special features of finite element analysis applied to reinforced concrete, including: constitutive relationships,...
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,...
