Sensitivity Analysis of Connection Stiffness in Orthogonal Frames with End-Plate Connections
According to AISC-LRFD specification (1986), two types of construction for steel frame structure can be assumed which are Type PR (partially restrained) and FR (fully restrained) constructions....

Cables Not in Trouble
Cable-stayed bridges in the U.S. are not, contrary to reports widely disseminated in the press several years ago, about to fail from corrosion. The design, in which primary cables support...

Developing High-Risk Scenarios and Countermeasure Ideas for Mitigation of Hazardous Materials Incidents
Kansas State University (KSU) conducted a comprehensive study of the development of a set of prioritized, extreme-risk scenarios, the development of a set of feasible, practical and implementable...

Highway Robbery: The Social Costs of Hazardous Materials Incidents on the Capital Beltway
In the summer of 1988, three major truck incidents involving hazardous materials occurred on the Capital Beltway in Washington, D.C. This paper estimates the delays that were incurred...

StateGEN/StateNET and DOT Guidelines: Tools for Highway Routing of Hazardous Materials
Under the sponsorship of the U.S. Department of Energy Office, of Defense Programs, Sandia National Laboratories' Transportation Technology Center has developed computerized...

The Pressuremeter: Some Special Applications
The preboring pressuremeter has been used for foundation design for many years. Some recent developments are presented which extend the applications of the pressuremeter. These developments...

Geotechnical Database Management Systems for Boston's Central Artery/Harbor Tunnel Project
This paper presents a geotechnical computer application currently in use on Boston's Central Artery/Harbor Tunnel (CA/T) Project. The application is designed to manage subsurface...

A Hybrid Expert System for Design with Geosynthetics
A prototype hybrid expert system is presented that selects geosynthetic materials and performs detailed designs for different geotechnical applications. An expert system is used to give...

Geotextile Edge Drain Design and Specification by Expert System
Expert systems can be developed and operated on personal computers to aid in the design of the geotextile filter component of pavement edge drains. The expanding use of geotextiles in...

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...

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...

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...

Reliability in Rock Engineering
This paper reviews approaches to reliability in rock engineering through a survey of methods developed at MIT. Since these methods are intended to be applied in engineering decisions,...

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...

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...
