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...
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...
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...
Lifeline Seismic Risk Analysis Impacts of a Catastrophic Earthquake on U.S. National Lifeline Systems
Electric power, water, gas, and oil pipelines, highways, railroads and several other lifelines of critical importance at the U.S. national level have been inventoried and analyzed, to...
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...
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...
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...
Post Earthquake Investigation Team
The CALTRANS Post Earthquake Investigation Team (PEQIT) has been in existence since 1971. It is an emergency response team which mobilizes quickly following a major earthquake to gather...
Evaluation of Techniques for the Seismic Modeling of Elevated Freeway Bridges
Following the October 1989 Loma Prieta earthquake in Northern California, a number of seismic parametric studies were performed for both two-level elevated freeways and single-column bridge...
Engineering Tactics on Lifelines Safety Against Earthquakes
Effects of sediment-filled valley on seismic ground motions have become of major interest in earthquake engineering throughout this decade. This paper presents interesting phenomena of...
A New Amplitude-Modulating Function and its Statistical Parameters for Seismic Ground Motion Simulation
This paper presents a new energy-based amplitude-modulating function and its statistics-based parameters for earthquake ground motion simulation. This function overcomes the main shortcomings...
Seismic Analysis and Design of RC Lifelines
