Response of Ductile Iron Pipelines at Parkfield, CA to Loma Prieta Earthquake
A field experiment designed to investigate the performance of buried pipelines at a fault crossing has been constructed at Owens' Pasture near Parkfield, CA. The site was...
First Experience Concerning the Seismic Behaviour of an Electric Power System in Eastern North America
The November 25, 1988, Saguenay earthquake of magnitude MbLg=6.5 occurred in the province of Quebec, Canada....
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...
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...
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 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....
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...
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 Analysis and Design of RC Lifelines
This paper describes the general approach for analyzing a soil-reinforced concrete lifeline system subjected to seismic loading, and the development and importance of transfer functions...
Earthquake Response of the San Francisco Freeway Structures During the October 17, 1989 Earthquake
In terms of strong motion shaking, San Francisco experienced a minor earth- quake on October 17, 1989. However, the San Francisco freeway structures (designed in the 1950s and 1960s) suffered...
Analysis of Automatic Vehicle Identification Technology and Its Potential Application of Florida's Turnpike
The Florida Department of Transportation contracted with the Center for Urban Transportation Research (CUTR) at the University of South Florida to conduct an analysis of automatic vehicle...
Case History of the Point Roberts Marina
This paper presents a fifteen year history of the design performance of the Point Roberts Marina. The 1,000 berth small craft harbor is located on the Strait of Georgia, immediately north...
Reef Breakwater Design for Lake Michigan Marina
An innovative breakwater concept consisting of a conventional breakwater and a submerged-reef breakwater operating in tandem has been designed for the southern end of Lake Michigan. The...
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...
Assessment of Cyclical Wave Damage for Small Basin Harbors
Since the construction of Oceanside Harbor in Southern California in 1963, continuous wave penetration into the inner harbor has caused significant damage to dock systems, revetments,...
Design Experience Gained Through Physical Modeling of Small-Craft Harbors
A research work unit has been initiated to determine the state-of-knowledge of small boat harbor design. Existing design criteria for small-craft harbor design is based primarily on 'rule-of-thumb'...
Physical Model Testing of Barbers Point Harbor and Marina Complex
