Seismic Decision Analysis for Jackson Lake Dam
This paper presents a framework for decision analysis that can be applied to seismic dam safety problems. The framework provides a means for displaying uncertainties in a manner that allows...
Probability of Facility Damage From Extreme Wind Effects
A probabilistic methodology has been developed to assess the risks of extreme wind induced damage to structures and facilities. The wind effects considered include dynamic pressure, atmospheric...
Evaluating Mitigative Options for Critical Facilities in Hurricane Prone Regions
This paper describes, and demonstrates the use of, a methodology to evaluate the safety of occupants in structures subjected to hurricane forces. Occupant safety is expressed in terms...
The Risk of Progressive Collapse of Single-Story Buildings in Severe Storms
The probability of severe damage and progressive collapse of single-story commercial, institutional and residential buildings is examined. Observations of actual damage and the results...
Research Needs to Resist Terrorist Attacks
The task of protecting facilities against terrorist attacks is very much a new problem for the U. S. civilian sector. Guidance as to what steps need to be taken by a municipality or a...
Reliability Revision for Structures in Service
Models of structural reliability are called upon to provide not only initial estimates of safety, but also revised estimates reflecting new information on the structure as it becomes available....
Ultimate Membrane Strength of R/C Shell Elements
The ultimate strength of reinforced concrete shell elements is governed by the yielding of steel and/or the compressive strength of concrete. Depending on which of these two conditions...
Application of a Hybrid Strategy for Structural System Reliability Analysis
The authors have attempted to explain a strategy for structural systems reliability calculations. In essence, it involves the use of different methods at appropriate times in the search...
Engineers in Court
Engineers who like debating often serve as expert witnesses. Though many avoid forensic work because they find lawyers intimidating, some like the challenge of explaining engineering principles...
Activity Center Development Impact Analysis
A flexible microcomputer spreadsheet analysis method is described for analyzing area-wide and localized impacts of new development in urban or suburban activity centers. The analysis approach...
Connecticut: A Success Story
The Connecticut Department of Transportation (ConnDOT) had warned the state legislature that its highways and bridges would continue to deteriorate without increased funds for inspection,...
Tunnel Saved by Flyash
When inspection early in 1986 showed that Detroit's Northeast Raw Water Tunnel was near collapse at one location, quick action and a unique use of flyash-cement grout or fill...
Fail Safe Management
Engineers are increasingly embroiled in cases where failure is defined as improper administration or management of a procedure instead of the collapse of a structure or the failure of...
Artist in Wood Structures
Julius Natterer is chairman on the Institute for Wood Structures at the Federal Institute of Technology in Lausanne, Switzerland, and designer of more unusual or unique wood structures...
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...
Synopsis: Ozark-Webbers Falls Turbine Repairs
The Ozark and Webbers Falls powerhouses were designed and constructed under the supervision of the U. S. Army Corps of Engineers and are located on the McClellan-Kerr Arkansas River Navigation...
Strain Gaging and Data Acquisition at the TLMRF
Strain gages are the major source of data for the TLMRF (Transmission Line Mechanical Research Facility) research program. Measurement of member loads and bending moments in lattice towers...
Costs of Truck Related Highway Damage to Alaska
The cost of pavement damage to the State of Alaska for truck traffic continues to be a very controversial topic. There is no simple answer since this cost is dependent upon pavement strength,...
Ester West Slide?A Case History
An 80 foot high embankment was benched into graphitic schist permafrost on a north facing slope approximately 25 miles west of Fairbanks, Alaska. Soon after construction approximately...
Finite Element Analysis of Concrete Armor Units Subject to Wave Impact
Concrete armor units are commonly employed for the protection of shorelines and rubble structures. Their design is primarily based on hydrodynamic stability. However, their structural...
