Measured to the Max
Engineers looking to model the behavior of a structure under seismic conditions often ignore the best source of data available: the building itself. Full-scale measurements of vibrations...
The Great Chicago Flood of 1992
In April of 1992, a breach in a freight tunnel caused the river that flows through Chicago to pour into city building basements, causing the city to shut down. Critical utility systems...
Perils of Point Loma
Rupture of the Point Loma sewage outfall in San Diego on Feb. 2, 1992, sent 180 mgd of primary-treated sewage coursing into shallow waters off the city's coastline. The article...
Earthquakes: A New Look at Cracked Masonry
Economics, fears of liability, and a strict damaged-buildings repairs ordinance have contributed to an extensive delay in the repair of masonry-infill buildings in earthquake-stricken...
Tensile Terminal
Few can miss a fabric roof that covers a 1.45 million sq ft area. The one covering the Denver International Airport's Landside Terminal complex (reportedly the nation's...
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...
Pressure Pipeline Design for Water and Wastewater
This committee report,
Dynamic Wind Loads
This chapter is concerned with the motions of cable stayed bridges that arise as a result of wind action. The aerodynamic phenomena that must be considered are vortex shedding, torsional...
Special Considerations for Railroads
In comparison with highway bridges, railroad bridges are generally characterized by a larger ratio between traffic and dead load, larger braking forces, smaller relative width of the bridge...
Seismic Design
For seismic design of cable-stayed bridges, the following characteristics are of importance: The cable-stayed bridges consist of various components with different structural properties;...
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...
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...
School Is In Session
Cost overruns, project delays and the city bureaucracy have given school construction a bad reputation throughout the U.S., particularly in urban centers. But as other construction markets...
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...
Numerical Analysis of Frost Shields
The term 'frost sheilding' has been used to describe the practice of using flat stock rigid insulation materials burial above a water or sewer pipe to reduce...
Impact of Cold Weather on Building Construction Scheduling
Weather impact on a building construction schedule is often significant in cold regions. Most deterministic scheduling methods are unable to directly account for the effects of weather...
Processed-Snow Foundation Design at the Summit of the Greenland Ice Cap
The design and construction of a processed-snow foundation berm for an elevated building located at the summit of the Greenland Ice Cap is described. Weather conditions and design provisions...
Environment One: A Master Plan Study for a New Scientific Research Station at the Geographic South Pole
The existing research station at the geographic South Pole is approaching the end of its useful life. This master plan study focuses on determining the technical and functional requirements...
Cold Climate Building Research at Wasa Base, Antarctica
During the Antarctic summer season of 1988-89 a permanent Swedish research station was erected at Dronning Maud Land, Antarctica. The station, named Wasa, is situated on a nunatak. A corresponding...
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...
