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...

An Expert System for Inactive Hazardous Waste Site Characterization
The area of hazardous waste management is a broad and multidisciplinary field requiring expertise in engineering, geology, chemistry and toxicology, and is an ideal area for the application...

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...

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...

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...

Cleaning Up Toxics
Case histories show how several different types of contamination cleanup were handled. In Attleboro, Mass., washwater, used to decontaminate equipment and tools after cyanide was removed...

Attapulgite: A Clay Liner Solution?
Poor performance of clay liners at waste management facilities has resulted in the EPA mandate of synthetic polymeric liner materials to comply with zero penetration requirements. Laboratory...

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)...

Pseudo-Dynamic Testing of Structural Components
The pseudo-dynamic testing procedure is a simultaneous simulation and control process in which inertia and damping properties are simulated and flexibility properties are acquired from...

Seismic Tests of Friction Damped Steel Frames
This paper presents the results obtained from qualification tests of a new friction damping system, which has been proposed in order to improve the response of Moment Resisting Frames...

Nonlinear Behavior of Precast Concrete Shear Walls under Simulated Earthquake Loading
This paper presents experimental and analytical results on precast concrete shear walls under earthquake loading. It was observed in both small scale models tested and the computer analysis...

Hysteretic Behavior of Composite Diaphragms
Floor systems constructed with steel-deck-reinforced concrete are described. When used to resist lateral loads these systems are referred to as diaphragms. A description of a test arrangement,...
