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...
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....
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 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...
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...
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...
Simplified Numerical Analysis on Earthquake Response of Irregularly Bounded Surface Layer
Evaluation of seismic response of a soft surface layer is the essence in a design of a lifeline in this layer. For this purpose, a quasi-three dimensional ground model was developed by...
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...
Marina Del Rey: 30 Years of Environmental Impact
Marina del Rey - the world's largest man-made recreational boating harbor - also holds primacy in pollution. Marina del Rey is home port to more than 6,100 vessels in wet...
The Application of a Structural Analysis Program to Floating Dock and Guide Pile Design
The floating dock systems and guide piles used in marinas are often designed using over simplified analysis techniques. However, if the dock system is flexible or if either the soil conditions...
Pressure-Treated Wood Effect on Marina Environment
Pressure treated Southern Pine and Douglas Fir are the most commonly used materials for marina construction in the United States. The preservatives currently used, creosote, chromated...
Meeting MARPOL Annex V Requirements, A Model for Recreational Ports and Harbors
MARPOL (an abbreviation for marine pollution) is an international agreement to reduce marine pollution globally. It is comprised of five annexes, and the purpose of Annex V is to reduce...
Avalon Harbor: Example of a Successful Destination Harbor
Avalon Harbor, which is located on the southeast side of Catalina Island approximately 25 miles (40 km) off the coast of Southern California, is an excellent example of a destination harbor...
