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...

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...

Fuzzy Reasoning for Earthquake Damage Assessment of Large-Scale City Gas Systems
A method for earthquake damage assessment is proposed for a large-scale city gas system. Since lifeline systems are usually laid in a large area and are composed of a number of component...

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...

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...

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...

Earthquake Loss Estimation Modeling of the Seattle Water System Using a Deterministic Approach
This paper summarizes the project and resulting report entitled Earthquake Loss Estimation Modeling of the Seattle Water System (Ballantyne, 1990) conducted under funding from the United...

Wellington's Lifelines in Earthquake Project: An Outline of a Major Review
This paper outlines a project involving a major review of all lifelines including building services in the region of Wellington, New Zealand. A case study approach was used involving representatives...

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...

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...

Applications of Strain and Deflection Monitoring Systems for Post-Earthquake Safety and Usability of Lifelines
The paper proposes and discusses a variety of strain and deflection monitoring devices and systems for post-earthquake safety evaluation of lifelines. There is clearly a need, both in...

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...

Understanding the Earthquake Environment, Corporate Strategies
Corporations should understand the impact that earthquakes may have on their ability to function. Some earthquake related issues which face a corporation are: earthquake design levels...

Preliminary Earthquake Mitigation Planning to Improve Watermain Performance in Vancouver, B.C.
City of Vancouver's water transmission and distribution system is vulnerable to over 1,000 pipe leaks or main breaks from a probable large earthquake (about 7.5 M). Cast iron...
