Dynamic Testing to Predict Static Performance of Drilled Shafts Results of FHWA Research
The paper describes the preliminary results of recent research sponsored by the FHWA on predicting by relatively economical dynamic methods, the static capacity and performance of drilled...
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...
Model Comparisons of Harbor Wave Response
Physical and numerical model tests were conducted for an idealized, flat-bottom rectangular harbor, entrance channel, and nearshore bathymetry. Bathymetry of the entrance channel and offshore...
Experiments on Stratified Flows: A Comparison with Theory
Stratified flows caused by salt wedges in estuaries, fjord flows and power station cooling waters represent very complicated flow situations with regard to their stability and rates of...
Scour Around Cylindrical Piles Due to Wave Motion in the Surf-Zone
The paper discusses the results of experimental tests to study scouring phenomena around cylindrical piles during a sea storm with reference to the modelling of a beach profile in the...
Management of Great Lakes' Sandy Barriers: The Conceptual Challenges
Sandy barriers are dynamic, significant, and sensitive resource systems, comprising portions of the 18,000 km of Great Lakes shore. Use, development, and management of these features,...
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...
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...
Suspended Sediment Load at Three Time Scales
Suspended sediment loads were examined at the three time scales of time-series-averaged, wave-by-wave and instantaneous during the wave cycle. Field measurements recorded on a natural...
Turbulence Modelling of Suspended Sediment in the Surf Zone
A computational model is developed for the prediction of the wave period averaged turbulence structure under a breaking wave. The principal forcing function for the model is the generation...
Process Variation Across a Barred, Tidal Nearshore
Detailed measurements of nearshore motions and morphologic change across the inner bar-trough of a barred, tidal beach were taken at Canaveral N.S., Florida. Tidal range was <1...
