Seismic Hazards for Memphis Water Delivery Systems
Estimation of seismic hazards is the first essential task in performing the seismic risk assessment of a municipal water delivery system. This paper presents the evaluation of seismic...

Seismic Vulnerability of Memphis Water System Components
The vulnerability of selected components of the Memphis Water System is evaluated herein for a 7.5 moment magnitude earthquake within the southern portion of the New Madrid Seismic Zone....

Serviceability Analysis of Memphis Water Delivery System
In this paper, Memphis water delivery system is introduced and its seismic performance is analyzed under various seismic conditions. Prior to the seismic analysis, a flow analysis of the...

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...

Spectral Shapes and Amplifications for the Loma Prieta Earthquake of October 17, 1989
The 1971 San Fernando earthquake provided engineers and seismologists with the largest number of strong motion accelerograms ever recorded for an earthquake at that time. Those records...

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...

Liquefaction Hazard Evaluation: Methodology and Application
Deterministic liquefaction potential evaluations are commonly done in engineering practice and several probabilistic models exist. In this paper an extended method is described that combines...

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...

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...

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...

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...

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...

Philosophy for Treatment of High-Pressure Natural Gas Pipelines at Active Fault Crossings
Natural gas from fields in the overthrust belt of southwest Wyoming will be collected and transported to Southern California. The proposed Kern River Pipeline will transport gas to Daggett,...

A New Amplitude-Modulating Function and its Statistical Parameters for Seismic Ground Motion Simulation
This paper presents a new energy-based amplitude-modulating function and its statistics-based parameters for earthquake ground motion simulation. This function overcomes the main shortcomings...

Simplified Uplift Analysis of Unanchored Cylindrical Tanks
Seismic tank damage has been reported in almost every major earthquake in the past, sometimes with serious environmental ramifications, thus raising concerns about the safety of these...

California Department of Transportation Seismic Retrofit Program: The Prioritization and Screening Process
Following the October 17, 1989 Loma Prieta Earthquake, the California Department of Transportation was designated as the lead agency to seismically retrofit all 23000+ public owned bridges...
