Seismic Risk of Water Supply Network
In this paper, the failure mode of buried pipeline is established considering such main factors as the slippage between pipe and soil, non-uniformity subsurface layer, and the stress concentration...

Analysis of Ground-Shaking Hazard and Risk for Lifeline Systems
This paper describes deterministic and probabilistic procedures for calculating ground-shaking hazard and risk for lifeline systems. Due to the large real extent of these systems, standard...

Investigating Fault Rupture Hazards: An Example from the Wasatch Fault Zone, Utah
The Kern River project consists of a 36-inch diameter high-pressure natural gas pipeline, to be constructed from southwestern Wyoming to southern California. The alignment crosses several...

Liquefaction Hazard Analysis for Design of the Kern River Pipeline at the Muddy River Crossing, Southern Nevada
The 91.4-cm (36-in.) diameter Kern River natural gas transmission pipeline will cross the Muddy River in Moapa Valley, about 5 km west of Glendale, Nevada, in an area of relatively low...

Seismic Hazards Associated with a Major San Diego Lifeline Corridor
Evidence for multiple Holocene earthquakes on the Rose Canyon fault zone in San Diego sheds new light on the seismic hazards of San Diego, and in particular, a major lifeline corridor....

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...

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 Risk Assessments of Small Earth Dams
A procedure has been developed which attempts to assess the risk of damage or failure of small earth dams and embankments when subjected to seismic input motions. The procedure is based...

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...

Seismic Behavior and Vulnerability of Pipelines
In this paper criteria and related features are described pertaining to the seismic design of pipelines and pipeline systems. The presentation begins by describing the past performance...

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 Analysis and Upgrade of Seattle Metro Wastewater Facilities
The Municipality of Metropolitan Seattle, Metro, provides wholesale wastewater transport and treatment for 30 cities and sewer districts. A Seismic Vulnerability Assessment Worksheet for...

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...
