Dynamic Responses of Buried Pipelines
The dynamic responses of the pipelines are analyzed by the continuous mass matrix method by considering the soil as a bounded plane in which the pipeline is placed. The friction between...
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...
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...
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....
Control of the Design Process
Gilbert/Commonwealth, Inc. (G/C) was the architect-engineer for the original design of the Florida Power Corporation (FPC) Crystal River Nuclear Plant, Unit 3 (CR3) and has been involved...
Design Features of Salvajina Dam
Salvajina dam is the second highest concrete face rockfill dam currently in service in the world. The characteristics of the foundation of the toe slab vary from fresh, sound and little...
On-Line Color Graphics for Demand-Responsive Scheduling
Scheduling and dispatching a fleet of vehicles to respond to ongoing requests for transportation to and from various points in an urban area can be a complex proposition. Human controllers...
Graphics-Based Transportation Modelling with DIME/GADS/NEDS
Graphics helps analysts, policy-makers and the public understand the inter-relationships of land use patterns and transportation systems. A suite of graphics-based programs provide a decision-support...
Long Range Element Update in Duluth, Minnesota
This paper discusses the use of microcomputer transportation planning software packages to update the Long Range Element of the Duluth-Superior Metropolitan Area Transportation Plan. Two...
Basic Freeway Section Design and Analysis
This paper presents the development and applications of an interactive, microcomputer-based program, FREWAY, for the design and performance evaluation of a basic freeway section with consideration...
Advances in Underground Pipeline Engineering
The field of underground pipeline engineering has undergone a rapid growth during the last two decades. The analysis, design, construction, operation, and maintenance of underground pipelines...
Vehicle Design Exchange With Other Disciplines
Vehicle Design as one of the eight designated areas of interest or 'disciplines' includes a wide range of interests within itself. It can range from overall vehicle...
Fluid/Structure Interaction During Seismic Excitation
Hydrodynamic loading and other fluid/structure interaction effects need to be considered in the design of structures which contain, surround, or are submerged in fluids when subject to...
Coupled Vertical-Rocking Response of Base-Isolated Structures
A base-isolated building can have a small horizontal eccentricity between the center of mass of the superstructure and the center of rigidity of the supporting bearings. The structure...
