Nonstationary Random Vibration with REDUCE
Computerized symbolic algebra, in conjunction with the code REDUCE, is utilized in dealing with nonstationary random vibration of single-degree-of-freedom systems. Application of REDUCE...
Outcrossing Rates By Point Crossing Method
The point crossing method is applied to compute outcrossing rates for general safe domains, i.e., nonlinear load combinations problems. For stationary processes the method typically yields...
Stochastic Model for the Management of a Stream-Aquifer System
The management of a system of groundwater and surface water requires that the hydraulic connection of the two sources be investigated. The inherent uncertainties that exist in the data,...
Optimal Use and Economic Value of Seasonal Runoff Forecasts

Building Code Requirements for Masonry Structures and Specifications for Masonry Structures
The proposed Building Code Requirements and Specifications for Masonry Structures presented in this book were developed by the Joint American Concrete Institute, American Society of Civil...
Foam Over Troubled Toxics
Foams are now being used to control noxious vapor emissions from hazardous waste landfills. Another use of foams is in control of vapors emitted by chemical spills and fires. This article...
Biological Treatment of Hazardous Wastes
Biological treatment�using nature's bacteria and fungi�sometimes costs as little as 10-20% as incineration. Wastes in any form�solid, aqueous and gaseous�can be treated biologically....
Priority Integrated Pipe Evaluation
The selection of the most suitable pipe for a given site involves the consideration of many factors affecting pipe performance. The factors to consider in sewer pipe evaluation and selection...

The objective of Con Edison's reinsulation project is to develop the materials and technology necessary to reinsulate those steam distribution mains having excessive thermal...
Corrosion Monitoring of Critical Service Pipelines
Corrosion, including microbiologically influenced corrosion (MIC), is receiving much attention as a significant piping material performance concern particularly for critical service pipelines...
Iowa's Experience with Various Types of Pipe in Natural Gas Service
The Utilities Division, Iowa Department of Commerce, is responsible for the rate, service, and safety regulation of utility companies in the State of Iowa. This paper will summarize a...
A Multilayered Model for Analysis of Composite Pipes
A multilayered model is developed to analyze the behavior of composite pipes, such as prestressed concrete pipe, to the combined effects of internal pressure and applied loads. The pipe...
An Investigation of Field Performance of Reinforced Plastic Mortar Pipes
Every year many new pipe materials appear on the market for various applications. One of the important factors the design engineer and the user should consider while evaluating new products...
The Use of Restrained Joint Ductile Iron Pipe
This paper addresses some of the problems we at U. S. Pipe have observed from restrained joint installations during the past several years and the solutions devised. The restrained joints...
Thrust Restraint of Buried Ductile Iron Pipe
It is the intent of this paper to present current state of the art thrust restraint design, present a basis for calculating required lengths of restraint, and to offer some practical suggestions...
Design of Ductile Iron Pipe Systems
To ensure a reliable, low maintenance infrastructure capable of withstanding the test of time, proper initial design is essential. The basis of the design standard for ductile iron pipe...
Sliplining with Ductile Iron Pipe
The utilization of Ductile Iron Pipe (DIP) as an alternative to be considered for sliplining rehabilitation of sewer pipelines is evaluated. A recent experience in sliplining a failing...
Rehabilitation of Terminal Ballast Water Piping
In order to maintain the integrity of the ballast water piping system at the Marine Terminal of the trans-Alaska pipeline, a composite lining system was installed in the 42-inch (1,067...
