Tension Pile Test
The California Department of Transportation is conducting FULL SCALE AXIAL LOAD TESTS of 34 piles. This research project/proof test is being jointly conducted by public agencies (Caltrans...

Predicting Turbine-Generator Foundation Vibrations
Two of the major considerations in the design of large turbine-generator foundations are to maintain the proper shaft alignment and to limit the vibration of the machine during operation....

Ductility Analysis of Overload and Settlement
The concept of sufficient ductility to avoid premature or brittle failures is gaining wide acceptance in structural engineering and is an important aspect in mitigating the consequences...

Prediction of Embankment Dam Breaching for Hazard Assessment
Downstream hazard assessments for dams require prediction of 1) whether a breach could form, and 2) the hydraulic characteristics of the breach for use in calculations of discharge and...

Rehabilitation of a Toe Drain
Old or improperly designed toe drains can cause trouble for embankment dams. Toe drains installed without proper filtering can provide an easy course for internal erosion and piping of...

Experimental Evaluation of Reservoir Bottom Remediation Material
Open trenches developed through a compacted clay liner on the bottom of a reservoir. An experimental investigation has been conducted to evaluate the feasibility of using silt-sized, nonplastic...

Geotechnical Modifications at Meeks Cabin Dam
This paper presents a summary of the geologic and geotechnical evaluation of a potential piping deficiency identified at Meeks Cabin Dam as well as description of remedial measures and/or...

Seismic Rehabilitation of Sardis Dam
Extensive subsurface investigation of the embankment dam revealed the existence of a weak layer of silt and soft clay in the original topstratum clay underlaying the upstream shell of...

MASSPORT Modernization
Construction began last fall on the Massachusetts Port Authority (MASSPORT) upgrade of the 50-year-old Paul W. Conley Terminal in Boston. When completed in 1994, this timber-pile-supported...

Plastic Piling
Composite plastic and steel piles are gaining acceptance throughout the United States. The evolving technology has produced a unique product which solves several problems related to use...

Installation and Routing of Critical Embedments at the Hanford Waste Vitrification Plant
During the preliminary design phase of the project, a study was conducted to develop concepts for routing embedded piping and conduit between the remote cells and the service corridors...

Global Approaches for the Nonconvex Optimization of Pipe Networks
Because the pipe network problem is nonconvex, two global search schemes, MULTISTART and ANNEALING, are employed to permit a local optimum seeking method to migrate among various local...

Pipe Network Optimisation Using Genetic Algorithms
A new optimization technique of generic algorithms has recently been successfully applied to pipe network optimization. In this paper a parametric analysis is carried out of the genetic...

Non Contact, Remote Sensing of Buried Water Pipeline Leaks Using Infrared Thermography
Subsurface water pipelines, sewer and buried utilities throughout America and the rest of the world range in age from hundreds of years old to brand new. They all have, however, one fact...

Design of Pile Foundations
This handbook, Design of Pile Foundations, provides information on foundation exploration and testing procedures, load test methods, analysis...

Modeling Beam Torsion in Prestressed Concrete Box Beam Bridges
This paper briefly summarizes the development of a specialized finite element model capable of predicting the elastic and inelastic behavior of beam-slab type prestressed concrete spread...

A Work Packaging Process Model for Petrochemical Plant Piping Construction
This paper presents a model for the current work packaging process for petrochemical plant piping construction. The basic foundation of the model is formed by identifying major decision...

Stress Analysis in Concrete with Cooling Pipes
A substructure method of finite element analysis is adopted in this paper to simulate heat transfer and thermal stresses in a concrete dam. The massive concrete structure is cooled by...

Resource Constrained Time-Space Scheduling Model
This study aims to develop a resource constrained time-space scheduling model, mainly aiming application to pipeline laying world for gas supply under roads in urban area. This model can...

Invasion of the Zebra Mussels
At first glance, the zebra mussel looked like doom for freshwater users in the Great Lakes: small, hardy, incredibly prolific European mollusks with an affection for freshwater intakes...
