Assessment of Transmission Line Foundations
Electric utilities are faced with the need to build new transmission lines or to upgrade existing lines to meet future demands. Because of economic constraints and the difficulty of obtaining...

Making Amends with Nature
The U.S. salmon population has been decimated in the last half-century, principally because of hydropower. In the nation's focus on alternate and clean energy sources, fish...

Cracking the Fire Code
Local building codes specify fire resistance for members in buildings and other structures, and structural engineers select materials and assemblies that have passed a standard fire resistance...

The Church on Stilts
Christ Church Cathedral is an Anglican church situated in the heart of downtown Montreal. Constructed in 1859, it is a perfect example of English neogothic architecture, characterized...

Tension Leg Platform
a State of the Art Review
Prepared by the Task Group on Compliant Offshore Platforms of ASCE. This report considers the analysis and design of tension leg platforms (TLPs),...

Pressuremeter Evaluation of Glacial Till Bearing Capacity in Toronto Canada
Glacial tills were evaluated at three Toronto sites, using conventional methods, the pressuremeter and full scale caisson load tests. The geologic environment and specific subsurface conditions...

Foundation Engineering Constraints in Karst Terrane
Cavity-prone carbonate rocks are found in many Appalachian valleys and represent a poorly recognized hazard. This paper reviews the nature of the problem of founding above these Cambro-Ordovician...

Influence of Geologic Development on Horizontal Stress in Soil
Geologic history commonly controls the stress in natural soils, so that an understanding of the geology allows an assessment of the horizontal stress. This paper describes mechanistically...

An Evaluation of Pile Design in Fraser River Delta Using In-Situ Tests
Modern methods of pile design often take advantage of in-situ test data. Thirteen axial pile capacity design methods have been evaluated using the results from eight full-scale pile load...

Cyclic Behavior of Natural Overconsolidated Clay in Two Loading Modes
One-way, stress-controlled, cyclic triaxial compression tests were conducted on a heavily overconsolidated (Ko > 1), slickensided, natural clay with a view to modeling its cyclic...

First-Order Estimation of Ko in Sands and Clays
The in-situ horizontal stress coefficient (Ko) is known to be the dominant design parameter controlling the side resistance of deep foundations....

Collapsible Soils in the Antelope Valley�California
Soils subject to hydroconsolidation, commonly referred to as collapsible soils, have a potential to undergo significant volume reductions upon wetting, with or without additional loading...

Helical Bearing Plate Foundations for Underpinning
Helical anchor foundations have been used in construction to provide resistance against uplift and compressive loading for structures such as transmission towers, tied walls, pipelines,...

Design and Construction of Stone Column Reinforced Cofferdams
A recent expansion of the North Carolina State Port Facility, at Wilmington, involved the use of six cellular cofferdams as earth retaining structures during dredging and final filling...

Jet Grouting to Construct a Soilcrete Wall Using a Twin Stem System
An existing coal loading pier located in Norfolk, Virginia was completed in 1961 for the purpose of loading ocean going ships. It was determined that dredging adjacent to the pier would...

Settlement Characteristics from Insitu Tests in Flyash Structural Fills
Flyash from the Baltimore Gas and Electric Company's plants was used to construct structural fills in thickness ranging from 5 to 25 feet (1.5m to 7.6m). Several warehouses...

Ground Modification for a 14-Story Structure Over a Deep Peat Deposit
The foundation design and construction for a 14-story reinforced concrete office building northwest of Minneapolis is described. The building's geometry provided unusual foundation...

Model Tests for Bearing Capacity of Vertically Reinforced Foundations in Sand
Laboratory model test results for the bearing capacity of strip foundation supported by a sand layer with semi-flexible vertical rod reinforcements have been presented. All test results...

Tangent Modulus of Piles Determined from Strain Data
When evaluating measurements of strain or telltale shortening of a pile subjected to loading test, precise knowledge of the 'elastic' modulus is necessary. By means of plotting and analyzing...

Load Transfer in Deep Foundations Under Repeated Axial Loading
An analysis is presented of changes in axial load transfer for deep foundations under repeated loading, compared with static uplift and compression loading. Existing load test data demonstrate...
