Microsilica Concrete: Properties and Applications
With the advent of microsilica concrete, a new generation of high to ultra high strength and high durability concretes have become commercially feasible and are now being specified and...
Spalling and Buckling of Ice Sheets
The effect of local eccentricity in the vertical direction on the magnitude of compressive strength of wide ice sheets is studied theoretically. Two new failure modes are identified: indentation...
Foundation Response of Arctic Structures to Time-Dependent Ice Loadings
Arctic structures are subjected to a variety of time-dependent loadings, the most important of which are those due to ice. An approach is presented for estimating the strength and deformation...
Improving Arctic Seafloor Soil Stability
Soft, low strength soil layers at or beneath the Beaufort seafloor mean that soil strengthening may be necessary to ensure the stability of oil exploration and production structures under...
Seabed Strengthening in the Arctic by Deep Mixing
Improvement of soft soil sites in the Beaufort Sea would increase the versatility and usefulness of bottom-founded gravity structures for both mobile drilling units and permanent production...
A Beaufort Sea Deepwater Production Structure
There will be a need for large crude oil production platforms in Beaufort Sea water depths between 20 and 50 m and at locations with soft seabed soils and far from readily exploitable...
Concrete Space Frame Applied to an Arctic M.O.D.U.
The BOUYGUES experience in the use of concrete space frame technology for civil works and the application of this technique, combined with high strength concrete and prefabrication, to...
Use of Rayleigh Waves in Liquefaction Studies
The Spectral-Analysis-of-Surface-Waves method is a new seismic method for efficient determination of shear wave velocity in situ. Vertical impacts applied to the ground surface are used...
Behavior of Drilled Piers in Layered Soils on Texas Barrier Islands
Twenty-eight full scale load tests and the results of 41 geotechnical studies were analyzed to correlate shear strength interpreted from field and laboratory test data with those derived...
Landslide Hazard Rating for the Oregon Coast Range
The landslide hazard rating system for shallow soils on steep terrain over hard sandstone has three components: ground water response to precipitation, soil shear strength (including root...
Abutment Seepage at Smithville Dam
After initial filling there was concern for the stability of Smithville Dam when higher than anticipated piezometric levels were experienced in the left abutment foundation. Concern heightened...
Permanence of Chemically Grouted Sands
Test specimens were prepared with one of three uniformly graded sands of a fine gravel and injected with one of five silicate or two polyacrylic grouts. The polyacrylic grouts showed no...
An Application of Probability to Rock Slope Design
This paper describes the use of probability and statistics in the slope design process. An example is presented of a high rock slope in an open pit mine. This slope is a major concern...
Bond Check for Concrete-Filled Steel Tubular Columns
In order that a concrete-filled steel tubular column may display a maximum bearing capacity for sustaining the long-term vertical loads transferred from the steel beams to the steel tube...
Beam to Column Stress Transfer in Composite Structures
To clarify the mechanism of the stress transfer from the steel beam to the composite column through the beam-column joint, eight exterior beam column assemblies were tested under reversed...
Shear Strengths of Concrete-Filled Steel Box Elements
This study evaluated the ultimate strengths as well as the effect of the ultimate composite actions of concrete-filled steel composites under combined bending, shear, and axial forces....
Seismic Capacity Evaluation of SRC Buildings
The Japanese standard for seismic capacity evaluation of existing composite steel and reinforced concrete (SRC) buildings was introduced. As it developed, based on the previously established...

Numerical Simulation of Soil-Pipeline Interaction in a Ground Subsidence Zone
In this paper, the flexural interaction between a buried pipeline and the surrounding soil is examined by employing a combined boundary element-finite element scheme. The flexural interaction...
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...
