Settlement of Shallow Foundations in Sands Selection of Stiffness on the Basis of Penetration Resistance
The paper discusses the use of the formulae of the theory of elasticity to compute the settlement of shallow foundations in sands when subjected to static loading. Special emphasis is...
Pressuremeter Stress Relaxation Testing in a Permafrost Tunnel
In the spring of 1988, a geotechnical testing program was carried out in the U.S. Army CRREL Permafrost Tunnel, located at Fox, near Fairbanks, Alaska. In all, some thirty cone penetrometer...
Stabilization of Collapsible Alluvial Soil Using Dynamic Compaction
The effectiveness of dynamic compaction for improving collapsible soils was evaluated under field conditions using full scale load tests performed on 1.5 m square footings. Tests were...
Group Efficiency of Piles Driven Into Sands: A Simple Approach
A simplified analysis for computing group efficiency of circular displacement piles in sands is presented. Pile installation is assumed to cause soil displacements in the horizontal direction...
Do Simplistic Methods of Foundation Design Produce Reliable Foundations?
Many foundations today are designed using deterministic (single value) analysis techniques which do not reflect the natural variability of soil properties. If the standard deviation and...
Settlement of Footings on Sands?Accuracy and Reliability
Twelve methods of estimating settlements of footings on sand were evaluated by comparing calculated settlements with measured settlements. Each of the methods was evaluated in terms of...
Modification of
The response of piles in a rectangular group subjected to lateral loading has been analyzed using a three-dimensional finite element model to evaluate the effect of pile spacing on lateral...
Hugo 1989 - The Performance of Structures in the Wind
The performance of buildings in the Carolinas during Hurricane Hugo, 21-22 September 1989, is reviewed. Wind speeds in most locations were below the design levels specified in the local...
Lessons Learned by a Wind Engineer
Surface wind speeds during the passage of Hurricane Hugo through the U.S. Virgin Islands and Puerto Rico are described. Although damage to the affected areas was extensive, an assessment...
Lessons Learned From Hugo About Building Design Trends
An investigation of 100 buildings was made to evaluate their resistances to Hurricane Hugo which occurred on September 21 and 22, 1989 at Charleston, South Carolina. A nearby anemometer...
Roof Wind Damage Mitigation: Lessons From Hugo
Hurricane Hugo caused extensive roof damage in Charleston, South Carolina and surrounding areas. Extensive field investigations have revealed the causes of many of the problems. This paper...
Surviving the Storm: Building Codes and the Reduction of Hurricane Damage
The link between adequate building codes, enforcement, and the level of damage experienced in major hurricanes was examined in a 1989 study by AIRAC, a public policy research group sponsored...
Lessons Learned from Hurricane Hugo and Future Mitigation Activities
This paper is given as a summary of many of the various conclusions presented in the symposium, Hugo One Year Later. This includes presentations dealing with the performance of various...
Offshore Platform Structural Verification and Requalification?The Regulator's Viewpoint of Aging Platforms
The regulator's viewpoint of the structural verification and requalification of aging offshore oil platforms is crucial to the continued production of oil and gas. For the...
Earthquake Measures for California OCS Platforms
The ability of a platform to withstand earthquakes is one of the primary design factors for platforms on the California outer continental shelf (OCS). This paper discusses (1) the special...
Controlling Nitrogen Loading to Coastal Waters
Of the countless contaminants that reach coastal waters, nitrogen is one of the most problematic and least regulated. There is ample evidence that many coastal embayments are overwhelmed...
Sediment Yield Location Maps
The West National Technical Center of the Soil Conservation Service is compiling a series of colored sediment yield location maps for the eleven western United States, as well as Alaska...
Mechanics of Cohesionless Sediment Transport in Coastal Waters
Conceptual mechanics-based models for sediment transport processes in steady and unsteady turbulent boundary layer flows are derived and discussed. To the extent possible the predictions...
Review Notes on Cohesive Sediment Erosion
Comments are made on issues related to surface and mass erosion phenomena associated with cohesive sediment beds, and the entrainment of fluid mud. The rate process theory is recapped...
Alongshore Sediment Transport Rate Distribution
The initial analysis of a new set of experimental data on alongshore sediment transport rate distribution is presented. The distributions were generally found to be bimodal but tended...
