Centrally Loaded Columns
The paper has given a detailed description of the chapter on centrally loaded columns that will appear in the 4th Edition of the Structural Stability Research Council 'Guide...
Frame Stability
The Chapter on Frame Stability of the Fourth Edition of the SSRC Guide provides guidance on use of several stability design procedures. These include Critical Load Concept, Second-Order...
Applied P-Delta Methods in the Design Office
At first glance some axioms of a P-Delta analysis appear to be paradoxical. First, the P-Delta effects are a direct function of the depth of the structure parallel to the wind direction....
Tall Building Stability -- Practical Considerations
Simple techniques for including lateral stability effects in the design of tall buildings are proposed. The application of these techniques in the design of a 66-story building is described....
Frame Stability - A Canadian Designer's Approach
The deficiencies and fallacies of the simplistic effective column length approach to frame stability are demonstrated through its application to a 57-story rigidly framed building structure....
Another Geotech Import: Deep Soil Mixing
A technique called deep soil mixing (DSM), imported from Japan, has been used to stabilize an existing dam foundation. When the Bureau of Reclamation discovered that Jackson Lake Dam had...
Milwaukee's Deep Tunnels�No Clone
Tunnel boring machines are excavating nearly 19 miles of tunnels 17-32 ft in diameter as part of Milwaukee's $1.9 billion upgrade of its sanitary sewage system. Laid out to...
The Sand Bar Hydroelectric Project: A Case History
The Sand Bar project's major features include a reinforced concrete intake structure; 3. 5 miles of twelve foot diameter hard rock tunnel; a reinforced concrete powerhouse...
Riverbank Stability and Monitoring at Grand Coulee Dam
The capability for hydroelectric power generation at Grand Coulee Dam was substantially increased following construction of the third powerplant in the mid 1970s. Increased river fluctuations...
Installation of Thermistor Strings in Test Borings: A Comparison of Methods and Results
Several test borings were instrumented with two thermistor strings, one inside and one outside an air-filled PVC casing to compare readings of both thermistor strings and the stability...
Lessons Learned From Examination of Membrane Roofs in Alaska
During 1984 and 1985 airborne infrared roof moisture surveys were conducted of membrane roofs at Army installations in Alaska. Many of these roofs were also visually inspected and cored...
Ester West Slide?A Case History
An 80 foot high embankment was benched into graphitic schist permafrost on a north facing slope approximately 25 miles west of Fairbanks, Alaska. Soon after construction approximately...
Arctic Stream Scour: A Case History
A small arctic stream on the North Slope of Alaska was monitored through one hydrologic cycle. The flow rate of the stream and the progress of its erosion through a breach into an adjacent...
Coal Mining in Alaska's Interior: Problems and Solutions
The Usibelli Coal Mine located in Healy, Alaska is currently the largest operating coal mine in the state of Alaska. The mine has recently increased production to nearly 1. 7 million tons...
Excavation in Hard Clays of the Keuper Formation
For the construction of a lock on the Main-Danube-Canal in South Germany a 30 m deep cut had to be excavated in the overconsolidated clays and claystones of the Keuper formation. The strength...
A Case Study of the Behavior of Seaport Facilities During the 1978 Miyagi-Ken-Oki Earthquake
This paper assesses seismic response characteristics of seaport facilities during the 1978 Miyagi-Ken-Oki earthquake by (a) compiling and assessing documented information from post-earthquake...
Landslide Dams in Japan
Damming of rivers by landslides is common in Japan because widespread unstable slopes and narrow valleys exist in conjunction with frequent hydrologic, volcanic, and seismic landslide...
Dynamic Soil-Structure Interaction for RC Lifelines
The behavior of buried cylinders merits attention because of the impact of lifeline survivability under earthquake effects, and failures may adversely affect many communities that employ...
Reshaping Providence
By moving railroad tracks, river banks and several roadways, Providence, Rhode Island is reclaiming some 45 acres in its downtown and capital districts. This public works package is the...
Container Wharves Supported on All Vertical Piles Embedded in Rock-Fill Dikes
In recent years, several container wharves have been planned and/or constructed which feature the construction of the wharf over a sloping rock-fill dike. The wharves utilize all vertical...
