Interaction Between Waves and a Floating Body with Tension Legs
A boundary element method has been solved to the coupling problem of a two-dimensional tension leg platform interacting with a monochromatic wave train. In the boundary element calculation,...

Computation of Wind Flow Around a Building
A numerical investigation of wind flow around a three-dimensional building is presented by solving weakly compressible flow equations, together with Smogrinsky's subgrid-scale...

Numerical Simulation of Dam-Breaking Waves
Recently, as a high-resolution numerical technique, the Total Variation Diminishing (TVD) method is applied to Aerodynamic shock problems successfully. In this paper, a Total Variation...

Comparative Time Domain Analysis of Some Available Analytical and Empirical Expressions for the Spatial Variability of Seismic Ground Motions
Simulations in space and time based on models for the spatial variability of seismic ground motions are generated. Displacement time histories are simulated through the spectral representation...

Time-Delayed Control of Nondispersive Continuous Systems
This paper deals with the noncollocated, time-delayed active point control of continuous systems. It considers systems of finite spatial extent which can be modelled by the undamped wave...

In Situ Determination of Smith Soil Model Parameters for Wave Equation Analysis
A methodology for in situ determination of Smith soil model parameters for wave equation analysis is presented. The method uses a small-rod penetration test in conjunction with CAPWAPC...

Measurement of Subsurface, Deep Foundation and Slab/Subgrade Conditions with In Situ Seismic, Sonic and Vibration Methods
Case histories are presented to illustrate quality assurance and forensic applications of nondestructive testing and evaluation (NDT&E) methods for in situ investigation of subsurface...

Wave Equation Modelling of the SPT
The stress wave propagation in the Standard Penetration Test (SPT) is described in this paper. It is shown that the SPT is a complex dynamic system and that both force and motion measurements...

Monte Carlo Simulations of the Dynamic Response of Pile Groups
A study is presented on the effect of variations of relevant parameters within a pile group on the vertical dynamic response of the group. These parameters include the shear wave velocity...

Data Base of Seismic Body Wave Velocities and Geotechnical Properties
A data base of seismic velocities measured in soils and standard geotechnical engineering material properties has been established at the U.S. Army Engineer Waterways Experiment Station...

Development of the South Carolina Coast 1959-1989: Prelude to a Disaster
The history of hurricanes on the South Carolina Coast is reviewed. It is shown that reasonable design wind and surge conditions could have been established before the rapid development...

Meteorological Aspects of Hurricane Hugo
Despite recent improvements in the accuracy of hurricane forecasting at a rate of about one-half to one percent per-year over the past decade, the population growth in coastal mainland...

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...

Performance of Building Resistance to Water, Waves and Erosion
Water damage to buildings due to Hugo was widespread and severe throughout low-lying coastal areas. Flood insurance claim payments have already exceeded $350 million, the largest payout...

Hurricane Hugo vs Critical Lifelines
Hurricane Hugo significantly affected the performance of critical lifelines in South and North Carolina. An overview of the performance of power supply, transportation, communication,...

Hugo's Sturctural Damage in Puerto Rico
The results of a study of the wind damages caused by Hurricane Hugo is presented. Cases involving wood structures, industrial steel buildings, multistory reinforced concrete buildings,...

An Overview of Hurricane Damage to Military Facilities and the Storm Recovery Role Played by the Southern Division Naval Facilities Engineering Command
Hurricane Hugo struck a major blow to the military's shore facilities at Charleston, SC and Sumter, SC. The Air Force Base at Myrtle Beach, SC suffered only minor damage....

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 About the Building Code Process?The Good, the Bad, and the Ugly
Building codes and standards exist to provide for the health, safety and welfare of the citizenry. Concern must also be given to the need to safeguard the economy lest major changes in...

Hugo - Lessons Learned
This paper is based on ground surveys along the South Carolina coast from Edisto Island north to Myrtle Beach. It also includes ground surveys as far inland as Charlotte, North Carolina....
