Telecommunications Facilities Earthquake Readiness Since San Fernando
The vertical rack architecture of telecommunication offices showed some weaknesses during the San Fernando earthquake in 1970. Efforts have been made since then to improve performance...
Seismic Vulnerability Assessment of Seattle Water Department's Water System Facilities
The Seattle Water Department (SWD) service area and watersheds lie in seismic zone 3, in which there is potential for major earthquakes (Richter magnitude 7.5 or greater). The SWD system...
Prediction of Seismic Damage to Water Supply Network
In this paper a method for predicting seismic damage to water supply network is presented. By taking the breakage of the joints of the pipeline caused by seismic wave propagating as main...
Restrained Underground Piping?Some Practical Aspects of Analysis and Design
This paper is a brief update of stress analysis techniques published earlier [1] to aid the analyst in qualifying continuous welded steel buried pipelines that are subject to seismic soil...
Seismic Analysis and Design of Buried Piping
Among the causes of damage to buried pipelines due to earthquakes, the one that is most complicated to analytically deal with and that is most credible at safety related sites such as...
Earthquake Response of Liquid-Filled Pipeline at Finite Depth Below Ground Surface
This paper deals with the problem of earthquake response analysis of pipelines, empty or fully filled with liquid and buried at a finite depth below the ground surface. Emphasis is placed...
Finite Element Analysis of Three-Way Joint of Buried Pipelines Under Earthquake Loads
A quasi-static finite element procedure for the stress analysis of three-way joint of buried pipelines under earthquake loads has been established by quasi-conforming thin circular cylindrical...
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...
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....
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...
Economic Impact of Earthquake Effects on the City of Everett's Lifelines
The economic effects of lifelines failures, caused by three hypothesized earthquake scenarios, in the city of Everett, Washington are estimated. The project team consists of lifeline seismic...
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...
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....
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...
