Three-Dimensional Nonlinear Study of Piles and Simplified Models
In a recent study the authors examined the effect of the nonlinear behavior of soil on the axial and lateral response of one or two piles due to monotonic and cyclic pseudodynamic loading...
KBES Applications to the Selection and Design of Retaining Structures
Knowledge-based expert systems (KBES) are computer programs, based on artificial intelligence (AI) techniques, designed to reach the level of performance of a human expert in some specialized...
Evaluation of Geotechnical Design Parameters by Expert System Techniques
This study refers to application of an artificial intelligence technique to evaluate geotechnical design parameters in the soil design definition. This complex evaluation is incorporeted...
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...
Group Effect in the Case of Downdrag
A summary of the various techniques available to calculate downdrag forces on pile groups is presented. In light of all these existing techniques, a simplified method is recommended. An...
Analysis of Geometric Mispositioning in a Vertical Pile Group
A straightforward procedure is described whereby an approximate, three-dimensional, nonlinear model for the analysis of pile groups is used to simulate errors in major group parameters...
Spatial Variation in Liquefaction Risk Assessment
Basic concepts and methods of random field theory, needed to characterize 'distributed disordered systems', are reviewed and applied to a soil liquefaction case...
Use of a Tie-Back Retaining Wall to Stabilize a Moving Landslide
After failure of a gravity retaining wall, a moving landslide was stopped and stabilized by a tie-back retaining wall. The design considered the active landslide and residual strength...
Watertight and Earthquake Resistant Joints for Diaphragm Walls
Different types of joints were constructed and tested in the field to evaluate the bond between concrete and partition plate, the effect of tremie pipe location to the quality of concrete...
Within the North Wall of Hugo (Personal Recollections of Being in the Wrong Place at the Wrong Time)
Our house is in Romain Retreat, a subdivision of lots of 1 1/2 -3 acres in Awendaw, S.C. approximately 20 miles northeast of Charleston off Route 17 and about the same distance from McClellanville...
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's Effect on Marina Structures
The author has visited over twenty-five sites along the South Carolina coast and in Puerto Rico to ascertain the effects of Hurricane Hugo on marina facilities. Types of structures evaluated...
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,...
Advisory and Mitigation Activities in the Carolinas
To effectively reduce losses from hazard occurrences, an active and agressive mitigation program is needed. Following Hugo, several important activities have been initiated, utilizing...
Structural Engineering Lessons Learned From Hurricane Hugo
Hurricane Hugo purported to be 'The Storm of The Century' caused considerable property damage over a tremendously large area effecting nearly everyone and every...
Architectural Lessons Learned From Hurricane Hugo
All of us in the building design professions have learned many lessons in the last year since Hugo. My experience, as with many of us in the design profession in Charleston, has been on...
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....
Masonry Performance in the Coastal Zone
Investigators from the National Concrete Masonry Association (NCMA) surveyed the coastal areas of South Carolina from Charleston to Myrtle Beach during a seven day period just after hurricane...
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...
