Performance of Different Retention Systems in Similar Soils
Performance behaviour of three deep braced excavations in a similar soil profile, in the Chicago area is described. At each site, different bracing systems were utilized. Methods used...
Issues in Evaluating Combined Repeated Loading of Deep Foundations
The capacity and load/displacement response of deep foundations subjected to combined modes of repeated loading can be significantly different from the response under single (axial or...
Response of Concrete Island Drilling System to Ice Impact Loading
The lateral stability and load/deformation characteristics of the Concrete Island Drilling System structure under ice impact loading conditions were studied. The 300-foot-square (91.5-meter...
The Role of Analytical Geomechanics in Foundation Engineering
The role of modern geotechnical analysis in foundation design is reviewed, and analysis methods are classified into three categories, depending on their level of sophistication. The benefits...
Use of POE/POU Technology at US Army Installations
A wide spectrum of adverse water quality characteristics has been experienced at US Army installations throughout the country. These characteristics, both interim and long-term in nature,...
An Investigation of a Pumped Storage Hydropower System
In order to provide a realistic basis of determining the viability of a wind-powered hydroelectric system at a potential site, an evaluation technique has been developed. Basically, this...
Analysis of Concrete Gravity Dams Using Microcomputers
Monenco Consultants Limited has developed a microcomputer program entitled 'DS2' for the stability analysis of concrete gravity dams. This paper discusses this...
New Roof for an Aging Temporary
The wartime temporary design of a 1942 industrial building justified use of green timber for its roof trusses and higher than usual allowable design stresses. Some 45 years later, a new...
Simulation for Construction Planning and Control
A prototype system was created as part of a research project for the U.S. Navy Construction Battalions (the Seabees) and has been given the acronym SEACONS (SEAbee Construction Simulation)....
Controlled Yielding of the Lateral Boundaries of Soil Retaining Structures
Lateral expansion of conventional or reinforced soil backfills is necessary to establish and maintain the minimum lateral stresses on soil retaining structures. Laboratory studies are...
On the Post-Flutter State of Cable-Stayed Bridges
This paper deals with the post-flutter vibrations of cable-stayed bridges. An approximate theory and an approximate analytical solution method have been established. A numerical example,...
Effect of Spatial Variation of Ground Motions on Bridges
The effect of spatial variation of ground motions on the response of a two-span bridge is presented. Perfectly and partially correlated earthquake ground motions are used as input motions...
Stochastic Properties of Wind Spectra
In the first part of this paper the correlation function of measured wind spectra is compared with theoretical correlation models assuming a stationary wind process. This comparison indicates...
Effect of Air Gap on Platform Reliability
A simplified reliability study of the effect of lateral wave forces impacting the deck of a fixed platform is presented. The reliability of the deck legs, considered the primary resistance...
Surgery in the Microgravity Environment
As man becomes more active in space, the possibility of major medical emergencies requiring surgical procedures will increase. Surgery in the microgravity environment involves many challenges...
Solutions to Space Station Designs
Any space station that is to be designed for extended human use may require gravity. The artificial gravity field required can be produced by rotating the structure. As the Soviets have...
Crossing A Freeway
The Washington State Convention and Trade Center in Seattle is being constructed on air rights spanning Interstate-5, adjacent to the seven acre Freeway Park that also spans the highway....
Cause and Elimination of the Deflation Zones Along the Atlantic City (New Jersey) Shoreline
After recent construction of several large hotels and apartment buildings directly fronting the Atlantic City boardwalk, large blowouts were observed to occur during the winter season...
U.S. Coast Guard Experience with Wave Turbines
Since 1980 the United States Coast Guard has been developing a lighted buoy for exposed areas and congested harbor entrances. The buoy hardware is of conventional design while the signal...
Computer Aided Simulation of Fluid-Structure Interaction Problems
