Response Charts for Designing Against Nuclear Overpressures
The single-degree-of-freedom equation of motion for an elastic-plastic system with a nuclear airblast overpressure forcing function is nondimensionalized and solved. Solutions are presented...

Cumulative Damage of Structures
Structural response records may be analyzed to estimate relative motions of civil engineering structures. Several methods are available for the estimation of cumulative damage on the basis...

Taking the Loss Out of Risk
Since Superfund was authorized in 1981 and 22,000 hazardous waste sites put on notice, funds for remedial action have peaked with $20 billion annual clean-up budgets projected. But to...

Journal of Performance of Constructed Facilities
The Journal of Performance of Constructed Facilities attempts to improve the quality of the constructed product through interdisciplinary communication. Papers examine the causes and costs of failures...

Maximum-Slew-Rate Nonlinear Control for Improved Transient Response in Hydrogenerators
This paper considers a linearized model for fixed blade turbines. This paper demonstrates that constant gate speed bang-bang control holds potential advantages over current control techniques....

Hydraulic Transients?Helms Pumped Storage Project
Pacific Gas and Electric Company's Helms Pumped Storage project is a large underground hydroelectric development which went into commercial operation in June 1984. Because...

Analyses and Field Tests for Hydraulic Transients Sultan Hydroelectric Project
Two in-line Francis units with their long discharge conduit and bypass valves present some unique problems in controlling hydraulic transients in this system. The problems were compounded...

Analysis and Testing of Transient Pressures at Camp Far West Hydroelectric Project
The objective of this paper is to present a comparative discussion of the results of theoretical analysis of transient pressures and of field tests performed on the Camp Far West Hydroelectric...

Transient Analysis of Variable Geometry Turbines
An interactive general purpose hydraulic transient computer simulation procedure is presented which is capable of performing transient analysis of variable geometry turbine installations....

Structural Design Optimization of Nonlinear Response With Adina
Procedures for sensitivity analysis and optimization of nonlinear structural systems with the computer program ADINA are described. Formulation of the structural optimization problem and...

Animated Response of Dynamic Systems
Understanding how a simple structural system responds to a dynamically applied load is a difficult concept for most students to grasp. The fundamental mathematical theory of this behavior...

RC Structures Under Severe Loads?An Expert System Approach
The authors propose the application of expert systems to the post-test assessment of specific structural systems. In the study reported, an existing expert system shell was employed and...

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...

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...

Fire on the Water
Incineration is a promising hazardous waste disposal technique. However, nobody wants an incinerator constructed near him, so waste handlers are considering burning hazardous wastes at...

Stochastic Finite Element Methods in Dynamics
This paper develops a stochastic finite element solution method utilizing a Neumann expansion of the operator matrix involved and at the same time, devises an efficient Monte Carlo method...

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...
