Concrete Pipe Trenchless Technology
Precast reinforced concrete pipe is the most commonly used pipe material for jacking operations. For over 90 years, concrete pipe techniques, procedures and applications established the...
Pipeline Design and Installation
The proceedings of the International Conference on Pipeline Design and Installation, held on March 25-27, 1990 in Las Vegas, Nevada, presents information on all aspects of pipeline design...
Sounding Out Buried Waste
Geophysical diffraction tomography (GDT) is a new remote sensing technique for quantitative high-resolution subsurface imaging. It is similar to optical holography where long wavelength...
The Great American Pyramid
For more than 50 years officials of Memphis, Tenn. have wanted to establish a link to their Egyptian namesake--and they will, through a pyramid. As opposed to its Egyptian forerunners,...
Evaluating Spring Flow Trends at Pipe Spring National Monument and Vicinity, Arizona
A study conducted by the National Park Service Water Resources Division is resolving if ground water pumping is causing spring flow declines at Pipe Spring National Monument (PISP). Ground...
Design of Steel Transmission Pole Structures
Use of Linear Programming for Hydraulics Problems
Water is becoming a more and more precious commodity worldwide with each passing day. At the same time, the optimum and most productive solutions to water control and utilization are becoming...
Pump Selection Program and a Better User Interface
Numerous highly innovative computer solutions to engineering problems are of little use to the practicing engineer because these programs are not supported by adequate user interface....
The Equivalence of Path and Node Methods for Water Distribution Network Analysis
This paper deals with the equivalence between commonly employed methods, path and node adjustment methods, for analyzing water distribution networks. The basic equations for steady-state...
Advances in Pipeline Materials
Pipelines transport water, storm run-off, process wastes, petroleum, natural gas, slurries, solids, sewage, steam and other fluids either by gravity or under pressure. Pipelines are also...
Selection of Hole Size for Fluidization Pipes
Two-dimensional fluidization experiments are performed on fine and medium coarse quartz sands at depths of 25.4 and 42 cm. Four supply pipes are used with orifice diameters of 1.587 mm...
OTEC Sea Water Systems Technology Status
A workshop was conducted in April 1988 to provide an expert critique of the fabrication and deployment options for the seawater systems (all piping required to draw the seawater) of land-based...
OTEC Seawater Pipe Cost Comparisons
Describes a material which can substantially reduce the cost of seawater pipes and two methods for building and deploying such pipes for use in land-based OTEC installations, outfall sewers,...
The Future of Steel Structures
The future availability of steel as a construction material is covered in this paper. The advances in the material, design fabrication and erection are discussed. The quality and quantity...
Field Performance of Fiber Reinforced Concrete Highway Pavements
This paper reports the evaluation of field performance of fiber reinforced concrete pavements. The concrete was designed for a compressive strength of about 40 MPa. Steel fibers with hooked...
Bond Stress-Slip Relationships of FRP Rebars in Concrete
A newly developed type of reinforcement bar for concrete, Fiberglass Reinforced Plastic (FRP) rebar, can be used advantageously in concrete exposed to marine or corrosive environments....
Inelastic Stability of Thin Walled Metal Tubes Under Cyclic Loading Conditions
This paper is concerned with an experimental investigation on the inelastic stability behavior of thin-walled tubular specimens of steel, aluminum and stainless steel, under cyclic loading...
Behavior and Strength of Telescopic Steel Shores
To study the load distribution between concrete floors and shores during construction, the non-linear axial load-shortening behavior of a single post shore must be modeled properly. In...
Significance of Yield Surface Corner-Like Effects in Inelastic Stability Solutions
This paper presents the author's experiences with finite element prediction of the inelastic stability of steel plate structures. The implications of linear versus nonlinear...
Instrumenting for Eternity (Almost)
Prendergast describes the safety features and instrumentation for a low level radioactive waste disposal facility planned for Illinois. Federal law requires that each state or group of...
