Factory-Built Pump Stations for Water Service
Booster pumps for fire protection in tall buildings and small sewage pump stations have been available for many years as factory-built packages. These packages include pumps, motors, controls,...
Pipeline Materials and Design
The proper use of pipeline materials and design is obviously paramount in the private and public works sectors. The introduction and proper use of new piping materials and design procedures...
Design and Operation of Pipeline Control Systems
More and more of the time of the engineer involved in the design and construction of a pipeline project is devoted to problems relating to the control systems to operate and monitor the...
Guidelines for the Seismic Design of Oil and Gas Pipeline Systems
Current knowledge on the practice of earthquake engineering for oil and gas pipeline systems is presented. Such systems typically consist of buried oil, gas, or product pipelines and aboveground...
What is UNIX?
UNIX is an operating system that is able to run a variety of machines. While most other operating systems are designed to go with particular software, UNIX can be easily adapted to run...
Temperature Effects on Lasers
While lasers have markedly improved the accuracy of engineering, air temperature gradients can reduce that drastically. Based on a sewer project that used lasers to align all the pipe,...
High Tech Is More Than a Look
Hollow steel section, also known as tubular steel, is being used for its clean dramatic look, its structural efficiency in compression, the economic efficiency of combining structure and...
Prestressed Concrete Pavements: Status Report
Prestressed concrete is cost-competitive with and requires less maintenance than conventional concrete, but acceptance of prestressed pavements in this country has been slow. While Europe...
Superplasticizers: Reducing Water in Concrete
Superplasticizers or high-range water reducers are new types of chemical admixtures which when incorporated into concrete can cause significant increases in its slump but without any loss...
Asphalt: Great Expectations
A $50 million, five year research program has been proposed for research into asphalt as part of the larger ($150 million) Strategic Transportation Research Study (STRS). The research...
Structural Trends in New York City Buildings
This story is based on interviews with some leading structural engineers in New York City. It highlights the major structural trends in building design in that city. Case histories of...
Electronic Computation
Dramatic changes have occurred in computer-aided structural engineering during the past 25 years. Computers have evolved from large, slow processors with little available storage to fast...
Recent Developments in Pavement Skid Resistance
As pavements wear, they lose some of their skid resistance. This article discusses some of the leading options for restoring a pavement's skid resistance. The possibilities...
Superplasticized Concrete Takes Off in Dallas
Some engineers are calling superplasticized concrete the most important advance in concrete technology in over three decades. Over the past four years superplasticized concrete has begun...
Coastal Structures '83
The objective of the conference Coastal Structures '83 was to develop in-depth discussion of the state-of-the-art and future needs concerning coastal structures. Design, construction,...
Geotechnical Practice in Offshore Engineering
The offshore industry as it exists today is just 30 years old. In that period the depth of water where structures are built has increased from a few feet to over 1000 feet. The performance...
Seismic Response of Buried Pipes and Structural Components
At nuclear power plants there are numerous underground safety-related pipes and structural components which are utilized in the operation of the plant. These underground components provide...
Restoration
After the San Fernando earthquake of 1971, California's State Capitol Building was declared an earthquake hazard and vacated. It took the most extensive structural and architectural...
Bridge
Seven Mile Bridge is the longest, continuous precast post-tensioned segmental concrete bridge in the world. In addition to its function as a main artery connecting the Florida mainland...
West Coast High-Rise Condo Opts for Ductile Concrete Frame
In the past, the vast majority of high-rise buildings constructed in earthquake prone areas of the West Coast have employed a steel frame. However, recent advances have made it feasible...
