Seismic Reliability Analyses of Large Scale Lifeline Networks
For assesing the seismic reliability of large scale lifeline networks we developed an algorithm which had only polynomial complexity to enumerate paths in the network. Using this algorithm...
A Rapid Post-Earthquake Damage Detection Method for Underground Lifelines
The present paper discusses a methodology for rapid, post-earthquake damage detection for underground lifeline systems. The methodology integrates model verification and system vulnerability...
Lifeline Seismic Risk Analysis Impacts of a Catastrophic Earthquake on U.S. National Lifeline Systems
Electric power, water, gas, and oil pipelines, highways, railroads and several other lifelines of critical importance at the U.S. national level have been inventoried and analyzed, to...
An Expert System for Diagnosis of Earthquake Proof for Underground Lifelines
This paper reports a fuzzy expert system for the diagnosis of earthquake proof of gas pipelines with the aid of OPS83 tool. The fuzzy theory was employed to estimate seismic risk on the...
Earthquake Loss Estimation Modeling of the Seattle Water System Using a Deterministic Approach
This paper summarizes the project and resulting report entitled Earthquake Loss Estimation Modeling of the Seattle Water System (Ballantyne, 1990) conducted under funding from the United...
Wellington's Lifelines in Earthquake Project: An Outline of a Major Review
This paper outlines a project involving a major review of all lifelines including building services in the region of Wellington, New Zealand. A case study approach was used involving representatives...
Applications of Strain and Deflection Monitoring Systems for Post-Earthquake Safety and Usability of Lifelines
The paper proposes and discusses a variety of strain and deflection monitoring devices and systems for post-earthquake safety evaluation of lifelines. There is clearly a need, both in...
Preliminary Earthquake Mitigation Planning to Improve Watermain Performance in Vancouver, B.C.
City of Vancouver's water transmission and distribution system is vulnerable to over 1,000 pipe leaks or main breaks from a probable large earthquake (about 7.5 M). Cast iron...
Loss-Reduction for Lifelines in a Federal Earthquake Insurance Context: Some Preliminary Issues
Through a two-year project, Dames & Moore has examined the topic of building or landuse loss-reduction measures in a federal earthquake insurance or reinsurance program. Loss reduction...
Engineering Tactics on Lifelines Safety Against Earthquakes
Effects of sediment-filled valley on seismic ground motions have become of major interest in earthquake engineering throughout this decade. This paper presents interesting phenomena of...
Seismic Analysis and Design of RC Lifelines
This paper describes the general approach for analyzing a soil-reinforced concrete lifeline system subjected to seismic loading, and the development and importance of transfer functions...
Elevated Water Tank Inelastic Seismic Analysis
In 1988, the Seattle Water Department hired CYGNA, a consulting firm, to assess the seismic reliability of their water system, since major earthquakes can occur in the area. Their study...
Simplified Numerical Analysis on Earthquake Response of Irregularly Bounded Surface Layer
Evaluation of seismic response of a soft surface layer is the essence in a design of a lifeline in this layer. For this purpose, a quasi-three dimensional ground model was developed by...
