Design of a Knowledge Based System to Convert Airframe Geometric Models to Structural Models
Airframe manufactures who use CAD tools to design airframes and finite element analysis software to analyze them, still generate the finite element models using semi-manual methods. Although...
Fault Diagnosis of Hazardous Waste Incineration Facilities Using a Fuzzy Expert System
The use of an expert system along with fuzzy fault tree analysis is discussed in connection with fault diagnosis of a hazardous waste incineration facility. This fault tree is a diagrammatic...
KBES and Interactive Graphics
Knowledge Based Expert System (KBES) is at research and testing stage at present. Engineers have begun to accept Interactive graphics System (IGS) as a tool in decision making. This paper...
Qualitative Physics and the Prediction of Structural Behavior
A key need in the application of expert systems to structural engineering design is the ability to predict structural deformation and stresses in the absence of a quantitative model. The...
Integration of Project & Business Planning
An annual business plan is an important document. The process of developing a long term strategy and the concrete action plan necessary for its implementation involves management analysis...
Training Programs for Engineering Consulting Firms
Engineering consulting firms heavily use and support in-house training programs. The objectives of these training programs are to: (1) supplement the graduate engineer's educational...
Traffic Barriers: A Second Chance
More motorists are killed each year after striking traffic barriers than any other fixed object except utility poles and trees. These deaths occur primarily because the guardrail or bridge...
Enhancing Highway Safety Through 3R Construction
The safety improvement programs specifically aimed at correcting high accident locations (HALs) are certainly helpful. These programs have resulted in sizeable frequency as well as severity...
An Analysis of Traffic Signal Safety Improvements
Identifying high accident rate locations and determining that they have an overrepresented type or pattern of accidents is an important first step in the safety improvement process. However,...
Base Isolation in the Design and Construction of Power Plant Structures
This technical paper summarizes the results of some of the recent studies performed to assure technical feasibility in isolating safety-related nuclear power plant structures. The particular...
New Techniques in Forced Vibration Testing
Forced vibration testing is a well established technique as indicated by references 1 to 8. This paper describes a system for forced vibration testing developed over two years during work...
Design and Planned Use of a 2-Kiloton Eccentric Mass Vibrator
High-level testing of large civil structures is usually not practical, due to structural damage considerations and available testing equipment. However, in the case of a joint American/German...
Frequency Domain Analysis of a Tank-Soil System
The dynamic response of an elastic cylindrical tank supported on a rigid base under a harmonic vertical excitation is analyzed taking into consideration its interaction with the foundation...
U.S.-Japan Coordinated Program on Masonry Research
An overview of the U. S. -Japan Coordinated Program on Masonry Research is presented. The program consists of parallel efforts in Japan and the United States to develop design methods...
Sequential Earthquake Response of an Earth Dam
Sequential earthquake-response records of the well-instrumented Long Valley earth dam (Mammoth Lake area in California) are analyzed and engineering interpretations are made. The dam,...
Importance of Phasing of Strong Ground Motion in the Estimation of Structural Response
In this paper, the influence on Fourier phase spectrum of seismic source directivity due to rupture propagation along the earthquake source is investigated. The phasing is described using...
Evaluation of Building Response Recorded During the Morgan Hill Earthquake
On April 24, 1984, the Morgan Hill Earthquake (Richter magnitude 6. 2) occurred within approximately 15 km of IBM Corporation's computer-equipment manufacturing facility located...
Dynamics of Fender and Rack Systems for Docking Ferries
A dynamic analysis of a ferry fender and rack system is developed based on the conservation of energy principle and Newton's laws of motion. The dynamics of the interaction...
A Critical Look at Building Instrumentation in Earthquake Engineering
This paper discusses different issues and requirements existing in the area of building instrumentation. Strategies and types of equipment currently being used by the United States Geological...
Dynamic Testing of Structures Using the RESCUE Technique
This paper describes the most recent phase of an NSF supported program at SRI International to develop the technique of repeatable earth shaking by controlled underground expansion (RESCUE)...
