Microcomputers and Design Codes: A Case Study
A microcomputer analysis of the thermal stress problem in reinforced concrete box sections was conducted. An explicit finite difference algorithm for a one-dimensional heat flow analysis...
Real Time Data Acquisition in Structural Testing
The process of data collection in real time for structural engineering can be generalized into a process called the real time sequence. The sequence has three major phases: preliminary...
Groundwater Modeling: Selection of Computing Systems
Results are presented for ten microcomputer systems evaluated with respect to system performance in solving a test case three-dimensional groundwater flow problem. The model used was the...
Best Management Practices Overview
In the general list of best management practices for stormwater control, many practices are currently being used. On-line retention and detention ponds are used frequently and their importance...
Cut-and-Fill Becomes Cut-and-Drain
The U.S. Navy's facility in Subic Bay, Philippines, is in a mountainous area which experiences 182 inches of rain per year. These factors plus weak soil, made necessary an...
Cleaning the Nut Island Outfalls
As an early component of a comprehensive program to reduce pollution in Boston Harbor, two 80-year-old cast-iron outfalls, each 60 inches in diameter and a mile long were cleaned in a...
Improved Urban Traffic Flow Through Signal Re-timing?California Experience
The California Energy Commission (CEC) has initiated a new program to re-time all of the 20,000 interconnected traffic signals in the state, the first of its kind in the United States....
The Electronic Road Pricing System in Hong Kong
This paper addresses the traffic congestion problem and issues relating to the experiment of the world's first pilot scheme on Electronic Road Pricing System in Hong Kong....
Design Flexibility Cuts Costs
The Los Angeles Water Department saved $5 million on a pipeline project by investigating the capabilities of pipe fabricators to furnish the pipe size required and by being open to alternate...
Risk Assessment of Sea Bottom Scouring Using Fuzzy Set Theory
An approach to the assessment of risk to buried pipelines from ice gouging is developed using Fuzzy Set Theory. Statistical procedures currently used to analyze ice gouge data are inadequate...
Route Thaw Settlement: A Probabilistic Evaluation
A methodology is outlined for assessing potential differential thaw settlement effects on structures due to permafrost degradation along transportation routes in the offshore, nearshore,...
Effects of External Loadings on Large-Diameter Buried Pipelines
Development of oil and gas resources in the far north has involved extensive use of buried steel pipelines. Buried pipelines, particularly onshore, are frequently subjected to heavy superimposed...
Soil-Pipeline Interaction During Ground Movement
The problem of the elastic interaction is examined between a pipeline or a group of connected flexible connected pipelines and the surrounding soil medium, which is induced by ground movement....
Technical Considerations for Beaufort Sea Pipelines
The development of Beaufort Sea fields requires construction methods and equipment for pipeline installation and trenching providing a balance between safety, reliability, and economy....
Earth Pressure on Underground Concrete Pipe in a Field Test
The cause of cracking at the sheetpile extraction in concrete pipes buried by the open excavation method was investigated by loading tests on the pipe and a field test carried out by Osaka...
Earth Pressure on Underground Rigid Pipe in a Centrifuge
A series of centrifugal model tests on underground pipes that simulate the actual construction process were carried out to investigate the earth pressure concentration onto the pipe (particularly...
Maintaining a Natural Gas Pipeline in Active Landslides
This paper deals with a pipeline section on both sides of Douglas Pass in west Colorado. Landslide activity in the area has been causing considerable problems and disruptions of the pipe...
Negatively Buoyant Flow in a Diverging Channel
Negatively buoyant (plunging) flow from a horizontal, constant width channel into a diverging channel has been studied in the laboratory. The study was undertaken to provide information...
Seismic Pope Support Construction Practices
During the mid 1970's the regulatory agencies controlling the design and construction of nuclear power plants began to demand stricter adherence to already existing codes...
Structural Retrofit for Nuclear Power Plants
Retrofitting of nuclear power plants is a major concern these days. Recent rulings of regulatory agencies have affected most of the generating plants in some way. The lessons learned from...
