Mining for Building Expansion
Engineers adapted mining techniques to tunnel under a vibration sensitive manufacturing operation to create new working space below. IBM workers needed more working space at their Vermont...
Civil Engineering in the Oceans V
This proceedings is a collection of technical papers presented at Civil Engineering in the Oceans V (CEO V) specialty conference held at College Station, Texas on November 2-5, 1992. Initiated...
Structures Congress '92
Compact Papers
These Congresses provide a forum for the practicing engineers, researchers and educators. The involvement of numerous ASCE Divisions has helped to create a program that will appeal to...
Cables and Anchorages
The following types of cables are generally used in cable stayed bridges: Parallel bars; Parallel seven wire strands; Parallel or semi-parallel wire cables; Locked coil strands and ropes;...
Stability of Cable-Stayed Brides
This chapter deals only with stability under static loadings. For aerodynamic stabilities and stability of structure under seismic loading, see the appropriate chapters. Both the towers...
Rethinking the Competitive Bid
Concern that the U.S. construction industry is losing its competitive edge is nothing new. Ironically, the problem is not so much rooted in foreign technical expertise as it is in our...
Rebuilding an Illusion
A dam that controls the level of Fall Lake, a major entry to the Boundary Waters Canoe Area Wilderness of northern Minnesota had to be rebuilt, but federal agents barred constructors from...
Under the Undersea World
Soil conditions in New Orleans are generally unfavorable to the construction of large structures, and exceptionally so along the Mississippi River banks, which tend to slide. But that...
Dome Over Orlando
The article describes Orlando's new City Hall, a 267,000 sq ft nine-story reinforced concrete tower, clad in granite-aggregate precast concrete panels and topped by a 120...
Cellular Sheet-Pile Floodwall
Williamson, W. Va., flooded 37 times in this century, will soon be guarded by a $41 million, 4000 ft floodwall being built by the U.S. Army Corps of Engineers. A series of 41 circular...
Soil-Pipe Interaction During Frost Heaving Around a Buried Chilled Pipeline
The freezing of soil water around a buried chilled pipeline leads to soil heaving, which is affected by the presence of the pipe. This process may eventually cause pipeline failure. The...
Experimental Study of Adfreeze Heaving of Augered Caisson Footings
In order to establish the required depth of augered caisson-type footings in cold regions and their optimal design against adfreeze heaving, an experimental field investigation has been...
New Admixtures for Cold Weather Concreting
Chemicals were tested for their ability to promote strength gain in portland cement concrete at low temperature. The admixtures depressed the freezing point of the mix water and accelerated...
High-Performance Concrete in All-Weather Deck Pours
A high-performance concrete mix enhanced with a combination of microsilica, superplasticizer, and high dosages of an corrosion-inhibiting, accelerating admixture (calcium nitrite); proved...
River Ice Research in China
Hydraulic research in China has concentrated largely on free surface flows, sediment transport, large hydraulic structures, and hydraulic machinery. River ice research activities are expanding...
A Mechanistic Approach to Pavement Design for Nome Airport
The analysis of performance and design of the pavement structure for the North-South runway at Nome Airport is based on the mechanistic approach. In the mechanistic approach, calculated...
Laboratory Observations of Macroscopic Failure Modes in Freshwater Ice
A review is presented of tests performed in the laboratory by several investigators on indentation in freshwater ice. A number of the observed failure modes are discussed. From the results,...
Some Questions on Fracture Mechanics of Ice and Ice Covers
Investigation of natural processes of deformation and fracture of ice covers, and processes of its interaction with icebreaker or ice-resistant structures requires as a rule considerations...
Effective Pressures Measured During Indentation Tests in Freshwater Ice
Indentation tests were conducted by pushing flat, vertical indentors of two different widths (50 and 100 mm) against the edges of floating, freshwater ice at different velocities (0.6-150...
Loads and Vibration Induced by Compressive Failure of Ice
In earlier work, attention was focussed on the narrow length of crushed ice adjacent to the structure, which was seen as the seat of vibration associated with ice crushing. Crushed ice...
