Development of a Plane-Strain Device for Soft Rock
Work is now in progress to build a plane-strain apparatus for 'soft' (unconfined compressive strenghts below 35 MPa) rock and concrete, based upon a passive,...
Commuting Computing
Portable computers come in many different shapes and sizes and boast many of the same features as desktop machines. Unlike desktop PCs, however, the key to getting the most use out of...
Gateways to Understanding
Automating engineering design processes are crucial to the growth and the very survival of professional services providers. The need to enhance their competitiveness and the value provided...
Seattle Swing
The swing bridge has long been out of favor in the U.S. because of the navigational hazard presented by mid-channel pivot piers. A consortium of engineers is updating the design to a state-of-the-art...
Projects That Point
This is only a small sampling of what we can expect inthis decade. An $80 million kiln at Port Arthur, Tex., reportedly the largest of its kind in the U.S., handles bulk solids and sludges....
Geosynthetic Shields For Dams
A series of large dams in Europe, waterproofed by geosynthetics, may become U.S. prototypes. In Europe, the faces of more than 30 large dams now contain geotextiles and geomembranes. In...
Variation in Design Practice for Lattice Towers
The design and analysis procedures employed for lattice transmission towers vary among countries, companies, and designers. This variation in design practice affects the relative reliability...
Modular Restoration Structures?A Versatile and Cost Effective Transmission Tool
Most electric utilities use a large variety of different types and designs of transmission structures. Because of this, it is not practical or economically justifiable for these utilities...
Optimum Design of Tapered Tubular Members
An algorithm for designing a tubular structural member with constant taper is presented. The design criterion is that the maximum absolute stress produced by a set of loading conditions...
Floor Response Spectra Including Structure-Equipment Interaction Effects
An efficient method for generating floor response spectra with the structure-equipment interaction effects is proposed. Floor response spectra are computed from a prescribed ground response...
Some Design Considerations During Construction
Certain construction failures are discussed with associated design conditions leading to these failures. Some points of interest for engineers involved with construction equipment designs...
On-Site Incineration
A variety of equipment is now available for incinerating hazardous wastes in situ. Thermal treatment, compared to land disposal, offers limited liability and immediate destruction. It...
ATC-23: A Survey of California Hospitals for Earthquake Survivability Potential
In September, 1986 the SSC recommended the completion of a survey of existing acute care hospitals as the first step in a program to bring about the upgrading of all pre-1973 hospitals...
Robotic Roundup
Robots are finding their way on to the construction site. Years of research and development have yielded unmanned machines that complete tasks as mundane as spotwelding and as dangerous...
Augered Cast-in-Place Piles
Development of the augered cast-in-place pile system from origination in the late 1940's to the present state of the art is presented, with methods of pile placement, including...
Owner and Designer Advantages Derived from Use of Construction Consultant
There are two significant ways that an experienced construction consultant can assist both the owner and the designer/engineer in obtaining an economical and practical structure. Constructibility...
Microcomputers: Investing in the Future
There is more to a successful computer system than simply going to the nearest supplier and buying the most up-to-date equipment. Engineering firms, while not being reluctant about installing...
The Program Manager: Mind Over Machine
Computers are now clearly entrenched in the office of the engineer. Their advantages are obvious; for one, they allow the engineer to instantly accomplish tasks that took weeks in the...
Automated Design of Wastewater Plants
Computers have been used for individual steps in design of wastewater treatment plants, and now these steps have been tied together, linked by an aggregate computer program the designers...
Real-Time and Off-Line Aids for Teaching Digital Control
This is a report of unique computer tools developed for teaching of the design of digital control systems at the University of Wyoming. The real-time components of the laboratory involve...
