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...
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....
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...
