Utopia Under Glass
We stand within sight of the day when our reserves of fossils fuel will be inadequate to maintain the type of energy inefficient cities we have grown used to. This exercise in urban planning...
Microtunneling: No Pipe Dream
Microtunneling machines developed in Japan and Germany can help install pipes, ducts and cables without disrupting urban activities at street level. A microtunnel is defined as having...
A Study of Exterior Facades?Problems and Solutions
The quality of the exterior facades of a building is important to maintaining aesthetic image, protecting the interior environment from infiltration of heat, cold, moisture, wind, and...
Geotechnical Data Acquisition and Computerized Analysis
In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for the improvement of Interstate 70 through...
Interactive Microcomputer Analysis and Design of Light Gage Steel Roof Systems
A hinderance to the widespread acceptance of the cold-formed steel roof Z-purlin in conventionally engineered buildings is due to the lack of a useful and efficient analysis and design...
SIMSUPER5: Tunneling Construction Simulation
This paper presents SIMSUPER5 (SIMulation SUPERvisor version 5) a computer program developed to simulate the tunnel construction process under conditions of uncertainty. The program determines...
Computerized Construction Progress Control
In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for interstate 70 through Glenwood Canyon,...
Technology Assessment for Hydrogen from Renewable Energy
This paper is a preliminary report on an assessment of technologies for hydrogen production from renewable resources, and an investigation of the problems and issues involved in assimilating...
Developing Renewable and Alternative Energy Sources
The development of small scale, renewable or alternative (R/A) energy resources was originally perceived as environmentally more acceptable than large-scale conventional projects. The...
Wind Effects on Compliant Offshore Structures
In recent years modern experimental and analytical techniques for estimating wind effects have increasingly been applied to compliant offshore structures. The six papers included in this...
Downtown Traffic Goes Down Under
Seattle's 1980 employment population of 124,000 is expected to jump to 150,000 by 1990. This will mean more commuter traffic and more mass transit coming into the city's...
The Concrete Diagonal
Onterie Center in Chicago, Fazlur Kahn's last major structural design, is a companion in concrete to the diagonally braced steel John Hancock Center. It is a mixed-use building...
Tunnel and Bridge Construction with Minimum Disturbance to Overhead Services
The rapid growth of pipe jacking over the last 20 years and the improvement and development of methods in terms of lengths of drive, size and ability to work in varying ground conditions...
Hydraulic Design of the Strontia Springs Diversion Dam
The hydraulic features which were of primary significance for the project were the diversion tunnel and spillway. The low-level outlet valves and water-supply intake were relatively straight-forward...
Santa Fe's Mobile Arctic Drilling Barge
There is a need for mobile units that can operate year-round in shallow Alaskan waters south of the Bering Strait for exploratory drilling and/or early production. Santa Fe has completed...
Deep-Water Platform Solutions for the Navarin Basin
The environmental conditions prevailing in the Navarin Basin may impose limitations on the type and shape of production, storage and loading structures. The magnitude of the wind and wave...
The 1984 novel
Design Considerations for Wind Loadings
The application of reliability concepts to the treatment of wind loadings on structures has increased in the past several years. Advances have been made in assessing the various uncertainties...
Acid Deposition in the Wind River Mountains
National attention has been focused on the discovery of acidified lakes in the Adirondack Mountains of New York and elsewhere in New England. It is commonly believed that the West, in...
Soldier Creek Dam Foundation Drainage
A possible mode of failure for Teton Dam, piping of erodible core material through unsealed foundation joints, was also concluded as being possible at Soldier Creek Dam, Utah. Evaluations...
