Stress-Intensification Factor and Flexibility Factor in Seismic Analysis of Continuous Buried Pipelines
The topics of intensified stresses and increased flexibility in pipe bends subjected to bending loads are discussed in this paper. Also discussed are dynamic strain compatibility between...
The Relative Strain as a Design Criterion for Buried uPVC Gravity Sewer Pipes
When designing buried plastic sewer pipes, the relative strain caused by deflection of the circular pipe section is of particular interest. The reason for increased interest is the present...
Dynamics of Buried Pipelines
Forced motion of pipelines due to stationary or moving loads is studied. The pipe is modeled as an elastic shell in an elastic (or viscoelastic) medium. The interaction of the shell and...
Strains Induced by Combined Loading in Buried Pressurized Fiberglass Pipe
In 1983 Owens Corning Fiberglas and Utah State University collaborated on a study of combined strain behavior of fiberglass pipe to quantify the bending strain reduction as a function...
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...
KEMCOR?A Chemical and Corrosion Resistant Piping System
KEMCOR is a new underground composite pipe system designed for chemical process use in such industries which require a high degree of corrosion resistance to varying concentrations and...
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...
Teaching Open Channel Design with Programmable Pocket Calculators
The goal of the basic open channel flow course is to present the theory of steady flow of water in open channels and some channel design practice. This paper presents the evolution of...
Microcomputer Simulation of Jets and Wakes
Illustrations are presented for radial jets and for turbulent flows in the wake of circular cylinders. The paper illustrates the use and importance of low-cost computational tools in engineering...
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...
Designing for Residual Flooding
Flood control projects should incorporate designs and responses for flooding of the protected areas due to exceedance, overtopping, or failure of the features. Design strategies for levees,...
Tidal Flooding Study for a Seattle Watershed
The paper reports on a study to develop a correlation between rainfall volumes and tidal storm surges based on recorded rainfall and tide data. This correlation was used to establish tidal...
Friction in Hurricane Induced Surges
Bed shear stresses induced by the flowing water are expressed by means of a friction factor for which formulas are developed for: ocean bottom, mangrove fringes and areas, forested areas...
Encoder for Flood and Irrigation Data Transmission
This paper covers the design and use of a new dual parameter encoder for real time telemetry in the fields of flood forecasting and irrigation. Some history and background is presented...
Application of Water Budget to Seepage Loss Estimation
The seepage loss for the emergency cooling water spray pond has been calculated by performing a water balance study for the pond. A field test of the spray pond was performed to estimate...
Computer-Based Design of River Bank Protection
A study using the FLUVIAL-11 computer model was made for the Rillito River in order to determine the design configuration for the bank protection which must contain the design flood and...
