Software Interface in Engineering Applications
The evolution of personal computer (PC) software has reached the point where most major types of software will interact. The ability of PC programs to share various texts, graphics and...
Settlement of Tanks on Clay
Steel tanks for storage of water, oil, and other liquids are capable of withstanding large, but not unlimited, settlements without damage. In most cases shallow foundations provide adequate...
Replacement of a Failed Embankment Designed to Accommodate Large Settlement: A Case Study
Thick deposits of soft, normally to slightly preconsolidated, organic clay are common at low elevations along the riverbanks of southeast Texas. Both the moisture content and liquid limit...
Settlement Analysis of Landfill Liners over Deep Mined Areas
Tensile strains due to differential settlement from past mining activities were evaluated for a landfill liner. The landfill cell encompasses 20 acres and is located on a subsurface profile...
Settlement Predictions at a Florida Port Facility
A paved container storage area approximately four acres in size has been constructed at the existing Port of Fernandina in Fernandina Beach, Florida. Approximately one-half of the site...
Nonlinear Undrained Lateral Response of Rigid Drilled Shafts Using Continuum Theory
The nonlinear undrained response of rigid drilled shafts under static lateral and moment loading is evaluated within the context of elastic continuum theory. The approximate approach utilizes...
Performance of a Steel Tank Founded on a Marine Clay
For tanks on soft clays, the soil is often preloaded before tank construction to increase bearing capacity and minimize post-construction settlement. In the case history described here,...
Measured Downdrag on Seven Coated and Uncoated Piles in New Orleans
A site outside of New Orleans, Louisiana was selected as part of a research effort to study the phenomenon of downdrag on bitumen-coated piles. Two steel pipe piles, two timber piles,...
The Role of Shale Pores in Settlement
Waste fills resulting from the mining of coal in Appalachia should ideally consist of large, free-draining sedimentary rock fragments. The successful performance of these embankments is...
A Study of Alkalinity Leaching and Residual Strength of Alkaline Stabilized Sludge
The addition of sufficient amounts of quicklime or other alkaline earth oxides to dewatered sludge raises both the pH and temperature of the sludge, resulting in microbial inactivation....
Practical Method for Scour Prediction at Bridge Piers
A practical method is presented for prediction of local scour at bridge piers which is based on a comparison of many well known equations and supported by field data. This equation includes...
Comparison of Headcut Advance Testing and Soil Test Results
This paper presents the results of a study conducted in a flume to determine headcut advance rates of two base soils compacted at various compaction moistures and placement energies. The...
Width Adjustment: Relative Dominance in Unstable Alluvial Streams
The mechanisms that control the relative dominance of width adjustment in unstable streams are described. Specifically, the role of the following factors affecting the fluvial environment...
Malaysia's Twins: High-Rise, High Strength
U.S. firms, following the market for new skyscrapers to Asia, are involved in design and construction of twin office towers in the commercial heart of Kuala Lumpur, Malaysia that will...
The New Clark Bridge: Saddle-Draped Cables
The new $85 million, 108 ft wide Clark-Bridge replaces a 20 ft wide 1928 truss bridge at Alton, Ill., carrying US 67 over the Mississippi about one mile above the recently completed Lock...
In Rehab We Trust
Glulam structures will be durable and last for a long time provided structural elements are protected from water and moisture. Once water is allowed to come into direct contact with glulam...
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...
Stiffness of Low Rise Reinforced Concrete Shear Walls
