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...
Microcomputers in Highway Drainage Design
This paper discusses some of the benefits and uses of microcomputers in highway drainage design and discusses the programs presently being developed. Subjects covered include hydrologic...
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....
APM System Performance and Guideway Design Parameters
Automated People Movers (APM) are a relatively new form of transportation system becoming popular over the last twenty to twenty-five years. They are characterized by fully automatic and...
Standardization of AGT Systems in Japan
Automated guideway transit systems (AGT) have been developped by different private firms in Japan, and therefore, the system components and dimensions are somewhat diversified. Such diversity...
Lille DPM System & VAL Family
This document provides a brief description of the different steps from the beginning to the total completion of the Lille downtown people mover (DPM) program in France. The system performance...
Development and First In-Service Use of Automatic People Movers in the Federal Republic of Germany, with Special Reference to the Magnetic Levitation System M-Bahn
People movers have been under development for the past 14 years in the Federal Republic of Germany. Of the four systems developed, two have been put into service. One of the two successful...
Emerging Technology?A Solution to Airport Access Problems
This paper reviews airports which presently have employed people movers, the problems they are solving, and potential use for solving access problems and create added value for the investment...
Brazil's Innovation in APM Technology
The paper discusses an automated people mover (APM) called an Aeromovel which consists of pneumatically-controlled vehicles weighing less than 20,000 pounds with a capacity of 300 passengers....
Unique Features of Automated People Mover Systems
This paper identifies the characteristics and unique features of the automated transit system presently being installed in the central business district of Detroit, Michigan. This system...
Detroit's DPM Maintenance and Control Facility
The Maintenance and Control Facility (MCF), a single building complex for the Detroit Downtown People Mover (DPM) system, incorporates the people mover system's transit vehicle...
Tensile Fracture and Fatigue of Cement Stabilized Soil
Portland cement stabilized soil is widely used as a base material for roads, airfields, and similar structures. Cracking in this material is studied using fracture mechanics concepts....
