Buried Fiberglass Pipe Performance and Installation Requirements and Design Calculations in International Standardization
This paper elaborates on a proposed standard covering details of fiberglass pipe buried installation requirements and criteria for selection of pipe stiffness. It also discusses the selection...
Characterization of Soil Arching Above Buried Conduits
Conventional ways of assessing the effects of soil arching over buried conduits were examined by means of finite element analyses. It was found that neither of the conventional soil arching...
Longitudinal Stresses in Buried Pipes
Longitudinal stresses are inevitable in buried pipes even in pipes with gasketed joints. Longitudinal stresses in any pipe section are cumulative. They include stresses due to soil friction...
Stress and Strain Responses of a Soil-Pipe System to Vehicular Traffic
A 16-in. natural gas pipeline near Racine, Wisconsin, had been in service for some 30 years. In 1982 road widening operations on a line parallel with the pipe presented the opportunity...
Inspection/Condition Analyses of Large Underground Pipelines
Inspection/Condition Analyses of Underground Pipelines (sewers and conduits) will be a necessary function of the pipeline Owner/Operator. The Condition Analyses and Inspection phases are...
Response of Buried Flexible Plastic Conduits Under Loading
Structural performance of 75 mm and 100 mm diameter plastic conduits embedded in Lloyd clay were examined experimentally in a laboratory soil bin, and numerically by the finite element...
Large Diameter Plastic Pipe Design
This paper presents a rationale for the design of large diameter plastic pipes for gravity flow applications. This procedure, applicable for all plastic pipes, adapts state-of-the-art...
Design of Non-Pressure Very Flexible Plastic Pipe
There is considerable debate about the correct structural design procedure to be used for very flexible plastic pipe (VFP) - typically glass-fiber reinforced pipe (GRP), reinforced plastic...
Proportioning Reinforcement for Buried Concrete Pipe
The proportioning of reinforcement between inner and outer cages that is specified in ASTM Standard Specification C76 for concrete pipe in sewer and culvert applications is examined in...
Application of Interactive Computer Simulation to Water Resources Problems in Civil Engineering Education
The major educational advantage of interactive simulation is expedient demonstration of system management and control procedures and interrelationships among system variables. An 8 year...
Advances in Selective Withdrawal
The authors present the results of recent selective withdrawal research in the form of a general mathematical description of this stratified flow phenomenon. A new description for boundary...
Input/Output Schemes for Microconverted Engineering Application Programs
When converting mainframe programs for microcomputer use, different input/output schemes are implemented depending on the type and volume of program data and ultimate use of the program....
Yakima Remote Control System: Supervisory Control and Data Acquisition
The Yakima Remote Control System is a computerized supervisory control and data acquisition (SCADA) system developed for the operation of the Bureau of Reclamation's Yakima Project in...
Response of Floating Structures in a Directional Sea
A finite element numerical model is presented to predict the behavior of long floating structures in a multi-directional sea. A follow up numerical model analyzes an important but mostly...
Vortices at Vertical Intakes
This paper presents the results of an experimental investigation designed to predict the formation of weak, free-surface vortices at vertical intakes with a headrace channel. A weak vortex...
Analytic Solution for Seepage from Saturated Soil Behind a Braced Wall
The locations of streamlines and equipotentials for two-dimensional flow in the vertical plane normal to a vertical retaining wall can be determined by various methods. Recent extension...
Cazenovia Creek Model Data Acquisition System
The purpose of the model is to reproduce river ice breakup phenomena for optimizing the design of an ice control structure. The performance of the ice control structure during a simulated...
Investigation of Design Criteria for APM Guideways
Designers have relied mostly on the provisions of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges. Sometimes...
Design Criteria Impacts on Guideway Development
A highly definitive design criteria or performance specification is frequently developed for new transit systems. The criteria are intended to protect the owner's interest...
Planning and Environmental Assessment of New Transit System
The guideway of the new transit system 'KANAZAWA SEASIDE LINE' which Yokohama City has started construction is designed as an elevated type throughout the line,...
