Vibration Induced Settlement From Blast Densification and Pile Driving
This paper describes settlement and vibration environments produced by two construction activities, blast densification and pile driving. Blasting is of interest because of the significant...
Movement of Foundations on Rock
This paper reviews methods for estimating the settlement of vertically loaded foundations on rock, with particular emphasis on shallow and piled foundations in and on soft rock....
Downdrag on Piles: Review and Recent Experimentation
A review of the literature on pile downdrag is provided, within the context of a recent full-scale study involving two pile groups driven in soft clay, subsequently surcharged by a 2.5...
Offshore Rescue
Restoration of wastewater ocean outfalls can be difficult, dangerous and environmentally challenging. Two recent projects, however, serve as examples of innovative outfall rehab. The first...
Bridge to the Future
The experimental Roize Bridge, near Grenoble, France, features an innovative composite space truss and unique modular construction methods for efficiency and economy. The Roize Bridge...
Fast Foundation for Soft Clay
This article describes the detailed foundation work and high-capacity piling design for a flue gas desulfurization (FGD) retrofit system for the Lambton Generation Station in Ontario,...
Input for Seismic Design of Major Structures
Effective seismic input considering the soil-structure interaction or soil-pile-structure interaction is presented. This approach takes the seismic wave as primitive input and considers...
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....
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...

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...
Vertical Erosion on Beaches and the National Flood Insurance Program
During the 25 years that the National Flood Insurance Program (NFIP) has been in existence, there has been an increasing recognition of the contribution of both episodic and long-term...
The Influence of Exposed Footings on Pier Scour Depths
Data compiled from past test efforts are combined in this article with the results of two new flume test studies. The combined material, presented graphically, suggests a method for adjusting...
Methods for Prediction of Maximum Scour at Coastal Structures
The most common coast scour-related problems are toe scour at rubble mound structures and vertical seawalls, and scour at the base of piles and horizontal pipelines. Existing scour prediction...
Analysis of Local Scour at Bridge Piers
Many studies have been performed on the cause and effects of local scour at bridge piers, and various prediction equations have been generated based on these studies. The general approach...
Connection of Grouted Tubular Insert Piles to Soil
Force transfer between offshore production jackets and tubular piles is effected by weld bead shear connectors, acting within the grout filled annulus between the piles and pile sleeves...
The Connecting Method of Steel and Concrete Using Long Deformed Bar Studs
A new welding technique for long horizontal studs of 19 mm and 22 mm diameters was established. The transmission of shearing and bending forces was evaluated using large model tests. Actual...
