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...
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...
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...
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...
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...
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...
Application of Lateral Spread Hazard Definition Using Liquefaction Susceptibility Index to the Design of Buried Pipelines
Recent liquefaction hazard studies have made use of relationships developed to provide direct estimates of liquefaction displacements interms of liquefaction susceptibility index (LSI)....
Gas System Repair Patterns in San Francisco Resulting from the 1989 Loma Prieta Earthquake
Leak repair calls in San Francisco were tracked immediately following the 1989 Loma Prieta earthquake. This information was subsequently obtained from PG&E and examined for possible...
Environmental Wave Barriers for Small Craft Harbors
This paper describes the history and development of the environmental wave barrier and the current planning and design being undertaken for a major expansion of the small boat harbor at...
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...
Joint Spacing for Airfield Pavement
This paper looks at various factors affecting portland cement concrete(PCC) pavement cracking, with special emphasis on the effect of joint spacing on crack development. A rational approach...
Pavement Experiences Indicative of Needs to Consider Design and Specification Revisions
Recent experiences on two airfield paving projects have indicated some problem areas which may warrant further consideration in design manuals and specifications. 1. Construction of the...
Microtunneling MARTA
Microtunneling technology was used to provide temporary support for two transit tunnels that were part of the extension of the Metropolitan Atlanta Rapid Transit Authority system. This...
Reliability-Based Design of Tunnel Support in Jointed Rock
The presence of joints in a rock mass may cause local instability of the tunnel support and its effect on safety should be included in design. Because of significant uncertainties in the...
Seismic Response and Vulnerability of Water Delivery Systems
The response and vulnerability of straight segmented buried pipelines subject to seismic wave propagation are investigated in this paper. Seismic damage to buried pipelines is briefly...
