An Expert System for Civil Engineering Applications
Civil engineering is a field where experimental knowledge has no substitute. Making experts' knowledge explicit and documenting and transferring it can have a great impact...

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...

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...

Reliability Analysis for Time of Travel in Compacted Soil Liners
Time of travel through compacted soil liners is difficult to predict because numerous factors confound the analysis. In this paper, the influence of spatial variability and uncertainty...

Geotechnical Engineering Design in the Age of the Modern Computer
Because geotechnical engineering requires that the materials and their configuration be investigated for each new project, the profession has always placed great emphasis on judgment....

Modification of P-Y Curves to Account for Group Effects on Laterally Loaded Piles
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...

Use of Bar Code Technology to Simplify Sieve Analysis Data Acquisition
A system has been developed at the U.S. Army Corps of Engineers Ohio River Division Geotechnical Engineering Laboratory using bar codes and a computer coupled balance to aid in data collection...

An Inexpensive Automatic Control System for Soil Testing
This paper describes an inexpensive automatic control system for soils testing. The system comprises a microcomputer, an analog to digital converter, a relay board, and solenoid valves....

Methodology for Optimizing Rock Slope Preventative Maintenance Programs
Rock slopes along transportation routes can fail in several different modes, with various types and magnitudes of consequences. The 'risks' associated with such...

Foundation Evaluation of Barkley Dam for Seismic Analysis
An in-situ site investigation was performed at Barkley Dam, KY to gather essential information on the stratigraphy and nature of the foundation soils. From this information the site was...

Finite Element Analysis and Field Instrumentation of a Soil/Cement Arch
A two dimensional plane strain finite element analysis is used to predict the increase in stress on an existing tunnel caused by the addition of twelve feet of fill. The fill, soil/cement,...

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...

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,...

Report on Hurricane Hugo and the Response to It by South Carolina Electric & Gas Company
The South Carolina Electric Gas And Company's response to the disaster began even before Hugo Struck. Company employees began preparing for the predicted onslaught. Workers...

Lessons Learned by a Roof Consultant
Hurricane Hugo left in its wake, extensive damage, an estimated $6 Billion loss. It is estimated that over 80% of the losses were related to roof failures, and the associated water damages....

A Post Hurricane Hugo Transportation Study
Hurricane Hugo will remain in the minds of South Carolinians for many years to come. This hurricane attracted most of the world's attention in 1989 as it devastated every...

Effects of Hurricane Hugo On Water and Wastewater Systems of the Charleston Commissioners of Public Works
Hurricane Hugo had a major impact on the operations of the Charleston Commissioners of Public Works in their effort to provide safe water and wastewater service to their customers. Through...
