Validating Expert System Prototypes Using the Turing Test
This paper describes the Turing Test technique to formalize the expert system validation process using a mature microcomputer based prototype expert system that has been developed to perform...
Improving the Graphical Interface in Transportation Planning Software
This paper examines the general issues that drive the development of graphics as a medium for transportation planners. Transportation planning has changed over time, and so has the nature,...
A Peak Hour High Capacity Reservation and Person-Based Functional Classification Concept for Urban Mobility Plans and Corridor Growth Management
The management of future growth and mobility in urban corridors and areas has been based in part upon use of the Levels of Service and procedures of the Highway Capacity Manual. Capacity...
Assessment of the Potential for Tectonic Fault Rupture for High-Level Nuclear Waste Repositories
Active faults that extend to or near the Earth's surface may threaten the safety of engineered structures. The threat can be mitigated by appropriate siting and design, which requires...
Engineering: Environmental vs. Developmental Goals
The 1992 winner of the Daniel W. Mead Student Paper competition explores the potential conflict for engineers, between environmental and developmental goals. Noting a dictionary definition...
Data Validation Practices and Risk Assessment
The accuracy of environmental site assessments depends on the validity of the data used to make them, but all too often, the people who judge the quality of the data have little idea of...
Banking on a Bridge
Completing the geotechnical design for the approach embankments and foundations for the Charter Oak Bridge, which crosses the Connecticut River between Hartford and East Hartford, Conn.,...
Data Base for Seismis Rick Assessment in Mexico City
We describe a model to estimate expected ground motions and expected damage, based on intensity damage relations derived for 14 classes of buildings representative of Mexico City construction....
Damage Assessment for Reinforced Concrete Buildings with Shear Walls
This paper tries to establish the analytical method of damage assessment for R.C. buildings with shear walls before or after earthquake. Incremental nonlinear spectrum analysis, using...
Code Provisions for Unreinforced Masonry Bearing Wall Buildings in California
Prior to the Long Beach earthquake of 1933, unreinforced masonry (URM) construction was usual in California, as it still is in many areas of the United States. The poor performance of...
Fundamental Issues in Seismic Safety in Midwestern U.S. Due to Hazard/Vulnerability Relation
Problems in establishing and mitigating seismic risk in urban areas when seismicity is not confidently based on instrumental records are discussed. Urban Southwestern Ohio is a specific...
Things That Fall?Lessons from Some Construction Accidents and Structural Failures
The causes and results of several construction accidents are reviewed. The lessons to be learned from such a summary are that all too often the simplest oversight leads to catastrophic...
Mitigation of Wind-Created Risks During Construction
Wind damage to structures during construction has been found to be significant and often catastrophic. Structural failures are often the result of wind loads that are far less than the...
Bridge Management Research Needs
The present article deals with some aspects of bridge management of particular interest to bridge engineers and to bridge users at the moment. It addresses questions such as life-cycle...
Seismic Assessment and Renovation Study for Highway Bridges
This paper is concerned with hazards mitigation on highway bridges due to earthquake ground motions. Damage to transportation systems may occur if the acting faults of May-Shan and Tsu-Kou...
Design of Stay Cables
Cable stayed structures, consisting of slender superstructure, stay cables and pylons are optimal systems for long span structures with regard to design an economy. The important function...
Developing a New Construction Policy for Bridge Management
The SHRP Program and other rehabilitation strategies are based on extending the life of concrete bridge elements. In the Bridge Inventory are a number of bridges that must be reconstructed....
Nondestructive Inspection of Steel Bridge Members
Assessment of the conditions of an aging population of bridges in order to determine the proper maintenance or retrofit operation is a challenge of great importance to bridge engineers...
Bridge Engineering and Life Cycle Cost
The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) requires that all Federal Aid projects must 'consider...the use of life-cycle costs in the design and engineering of...
Reliability-Based Expert Systems for Optimal Maintenance of Concrete Bridges
In this paper ongoing research in the CEC supported BRITE/EURAM project P3091 is presented. In the project reliability based expert systems for inspection and maintenance of corroded reinforced...
