TL;DR: The authors found that business owners rate electricity as the most important lifeline service in the area following the 1993 Midwest floods, and that electricity interruptions were widespread, were perceived by business owners as very disruptive, and were a much more significant source of business closure than actual physical flooding.
Abstract: Surveys in Memphis, Tennessee and Des Moines, Iowa indicate that business owners rate electricity as the most important lifeline service. In Des Moines, where the survey was conducted following the 1993 Midwest floods, proprietors tend to assign greater importance than memphis business owners to other lifeline services. Data on the business impacts of the 1993 floods indicate that lifeline service interruptions were widespread, were perceived by business owners as very disruptive, and were a much more significant source of business closure than actual physical flooding.

TL;DR: In this paper, an assessment of the seismic hazard that exists along a major crude oil pipeline (pipeline 22) is presented, where an 1811-1812 type New Madrid earthquake with moment magnitude 8.2 is assumed to occur at three locations where large historical earthquakes have occurred.
Abstract: This paper presents an assessment of the seismic hazard that exists along a major crude oil pipeline (pipeline 22). An 1811-1812 type New Madrid earthquake with moment magnitude 8.2 is assumed to occur at three locations where large historical earthquakes have occurred. Six pipeline crossings of the major rivers in West Tennessee are chosen as the sites because of the liquefaction potential at these sites. A seismologic-based model is used to predict the bedrock accelerations. Uncertainties in three model parameters, i.e., stress parameter, cutoff frequency, and strong-motion duration are included in the analysis.

TL;DR: In this paper, the authors present a description of the current state-of-the-art of seismic design criteria and design procedures for pipelines, and associated facilities and structures, including consideration of such factors as the earthquake hazard, design seismic motions and response spectra, and geotechnical factors affecting design.
Abstract: This paper contains a description of the current state-of-the-art of seismic design criteria and design procedures for pipelines, and associated facilities and structures. The criteria pertain to both aboveground and belowground pipelines and includes consideration of such factors as the earthquake hazard, design seismic motions and response spectra, and geotechnical factors affecting design.

TL;DR: In this article, the application of smooth geotextile liner materials to seismic base isolation of shallow foundations has been evaluated using laboratory testing and numerical analysis, which indicated that the prototype system is an effective means of reducing the transmission of strong ground motions to foundations of structures.
Abstract: The application of smooth geotextile liner materials to seismic base isolation of shallow foundations has been evaluated using laboratory testing and numerical analysis. Laboratory testing of single layer synthetic liner (SLS-L) base isolation systems included both shake table testing under sinusoidal and earthquake-like base inputs and dynamic centrifuge model tests using earthquake-like base inputs. Results of the laboratory tests indicate that the prototype system is an effective means of reducing the transmission of strong ground motions to foundations of structures. Based upon these results, a more sophisticated layered synthetic liner-soil (LSL-S) system is recommended for further investigation as a practical, effective, and economical means of seismic base isolation.

TL;DR: In this article, the authors describe the past performance of pipelines in earthquakes and identify the key ground motion parameters, geotechnical parameters, and structural factors of concern in design of pipeline systems.
Abstract: 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 of pipelines in earthquakes, and identifying the key ground motion parameters, geotechnical parameters, and structural factors of concern in design of pipeline systems. The seismic effects addressed include vibratory effects, relative ground motion, surface faulting, soil liquefaction, landslides, tectonic uplift and subsidence, and traveling seismic waves, all of which can lead to overstraining. Techniques for estimating these effects and for handling them in design, including connections and penetrations, soft soil bedding, and transition from soft to hard zones, are described, with reference to where more detailed analysis and design treatment can be located.
