Cross-Impact Analysis for Lifeline Interactions
A probabilistic method to evaluate the seismic risk of urban lifeline network systems is presented with emphasis on the interactive aspects of lifeline earthquake disaster. First, the...

Fuzzy Reasoning for Earthquake Damage Assessment of Large-Scale City Gas Systems
A method for earthquake damage assessment is proposed for a large-scale city gas system. Since lifeline systems are usually laid in a large area and are composed of a number of component...

GIS-Based Interactive and Graphic Computer System to Evaluate Seismic Risks on Water Delivery Networks
As interactive and graphic computer system to evaluate seismic risks of an arbitrary water delivery network is developed, based on G/S (geographic information system) software, ARC/INFO....

Earthquake Loss Analysis for Lifelines
The main focus of this paper is to demonstrate the practicality of the recently developed methodology for earthquake loss estimation for lifelines as well as to demonstrate the usefulness...

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...

Seismic Hazard Analysis of Buried Pipeline for Design
This paper concerns mainly the following three items on seismic hazard analysis of buried pipeline for design: (1) effects of pipeline length on risk, (2) effects of local site conditions...

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...

A Methodology for Assessing the Risk of Hazardous Materials Release Following Earthquakes?A Demonstration Study for the Los Angeles Area
A methodology for estimating the risk of post-earthquake hazardous materials releases was developed for the National Science Foundation and the National Center for Earthquake Engineering...

Seismic Vulnerability Assessment of Bridges on Earthquake Priority Routes in Western Kentucky
This paper discusses the current conditions of 203 bridges on the priority routes in Western Kentucky and their vulnerabilities to earthquakes. A span-loss type of bridge collapse due...

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...

Evaluation of Automatic Earthquake Shutoff Valve Performance and Recommendations for Future U.S. Standards
Increasing interest of local and state government has developed in recent years regarding legislation requiring automatic shutoff valves for natural gas lines as well as lines containing...

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...

Post Earthquake Investigation Team
The CALTRANS Post Earthquake Investigation Team (PEQIT) has been in existence since 1971. It is an emergency response team which mobilizes quickly following a major earthquake to gather...

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
