Inventory and Seismic Loss Estimation of Portland Water/Sewer Systems GIS Application to Buried Pipelines
Portland, Oregon has been identified by USGS as one of the earthquake-prone areas, in which earthquake hazard mitigation is important. This project develops an efficient and realistic...
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...
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...
Modeling Path Effects in the Los Angeles Region
Path effects for seismic wave propagation within three-dimensional (3-D) basin structures are analyzed using a reciprocal source experiment. In this experiment, a numerical simulation...
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...
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...
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...
Reliability of Highway Bridge Columns Under Earthquake Loading
Seismic design procedure for highway bridges normally specify that any inelastic action be confined to the columns. Concrete bridge columns are usually designed to resist an elastic force...
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...
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...
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...
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...
Seismic Design Criteria for Transportation Structures
Seismic criteria for the design of transportation stuctures have evolved slowly since their inception in the early 1940s. Although seismic design criteria are far more sophisticated than...
