Seismic Analysis of Buried Pipelines Subjected to Vertical Fault Movement
Earthquakes have demonstrated the vulnerability of buried pipelines, mainly to 'non-dynamic' seismic deformations of the ground, such as liquefaction, landslide...
Evaluation of Earthquake Resistance of Buried Continuous Pipelines at Bent Parts
Small diameter pipelines are susceptible to damage at bends due to large seismic ground displacements. The 'Deformability Index' is defined as the earthquake...
Hybrid Response Analysis of Buried Corrugated Pipeline Under Seismic Wave
Polyvinyl chloride and polyethylene corrugated pipes are recently used for buried water or sewer pipelines and also used as containers for electric cables. Seismic behavior of these pipelines...
Seismic Response of Buried Pipeline System in a Soil Liquefaction Environment
A project to study the general seismic response behavior of buried pipeline systems during a soil liquefaction process has been initiated at Old Dominion University. Pipeline systems could...
Performance of Pipelines During Soil Liquefaction
This paper presents the behavior of buried pipelines during soil liquefaction through reconnaissance work after the 1989 Loma Prieta Earthquake and response analysis based on a beam theory....
Inelastic Behaviors of Pipelines Buried Through Liquefiable Zone
For the case of a major pipeline transmission system buried through in soil deposits that may be susceptible to liquefaction, its seismio environments can be considered in the following...
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...
Earthquake Loss Estimation of the Portland, Oregon Water and Sewage Systems?Evaluation of Concentrated Facilities
This paper summarizes a report that provides an inventory of concentrated water and sewage facilities in two selected drainage basins in the City of Portland. Concentrated facilities include...
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...
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...
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....
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 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...
A Rapid Post-Earthquake Damage Detection Method for Underground Lifelines
