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...
Sponge Distribution at Arraial do Cabo, SE Brazil
Spatial and temporal distribution of shallow water sponges were studied on southeastern Brazilian rocky coasts by means of qualitative and quantitative samples made by SCUBA diving. Cluster...
Method for Treating the Stochastic Nature of Water Level and Wave Climate in Determining Economically Optimal Channel Depth at Small-Boat Harbors
Engineering and economic aspects of channel depth at small-boat harbors is discussed. The concept of wave-adjusted water level is shown to be important to specifying channel bottom elevation....
Importance of the Surf Zone of Exposed Sandy Beaches for the Development of Juvenile
Sandy beaches dominate most of the tropical and temperate coastlines. Studies of nearshore ichthyofauna, in different regions of the world, have revealed the frequent occurrence of juvenile...
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...
Ecological Studies at Espirito Santo Bay?Brazil Zooplankton Communities
Espirito Santo Bay is a coastal-tropical system, with strong water renovation cycle, which in turn adequate conditions to the development of many planktonic species (Bonecker et al., 1989)....
Saline Intrusion in Marine Effluent Outfalls
The paper presents an experimental investigation of saline intrusion in long sea outfalls. This intrusion is caused by the influx of sea water that may occur during periods of low discharge,...
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...
An Overview of Chemical Contaminants Throughout the Coastal and Estuarine United States
Informed decisions on the use and management of the nation's resources requires convenient access to current and reliable information. Since 1984, the National Oceanic and...
Basic Physical Models in Sediment Transport
Basic particle dynamics and cellular automata micromodels of clastic sediments are described and applications are illustrated in the areas of aeolian saltation, bedload transport, size...
