title: Earthquake Response and Rehabilitation of Critical Lifelines (NEES-2010-0918)

description: &lt;p&gt;&lt;strong&gt;Title:&lt;/strong&gt; Earthquake Response and Rehabilitation of Critical Lifelines (NEES-2010-0918)&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Year Of Curation: &lt;/strong&gt;2014&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Description: &lt;/strong&gt;Lifelines include underground water, waste and storm disposal, natural gas, and liquid fuel pipelines, electric power cables, and telecommunication conduits that are critical for public health, security, and economic well-being. A large part of US lifeline systems are old and have deteriorated. To restore the health of these aging systems, special technologies have been developed to insert pipe linings, composed of polymers, into existing underground lifelines without digging them up and disrupting surrounding communities. The research will substantially improve the performance of underground lifelines during both earthquakes and daily use by investigating how polymeric linings improve their resistance to ground shaking and ground failure. The research involves a strong university-industry partnership with pipe lining companies, public utilities, and engineering firms. The testing capabilities at the Cornell NEES Site are ideally suited for simulating ground rupture effects on pipelines to reproduce upper bound conditions of deformation in the field. The dual shake table capabilities at the University at Buffalo NEES Site are uniquely qualified for simulating seismic wave interaction with pipelines, especially for replicating the critical condition of closely spaced weak joints and defects. Guided by full-scale simulations, computer models will be developed, including 3-D models of the composite pipeline, liner, and soil system. The intellectual merit of this award involves combing state-of-the-art, full-scale experiments with advanced computational procedures to develop and validate the next generation analytical models. These models will support design and construction to apply in situ lining technologies for seismic risk reduction as well as improve design and construction practices associated with liner rehabilitation of critical underground infrastructure. The research will also explore the use of flexible electronics to embed micro-sensors, and thus create &quot;intelligence,&quot; in lining systems.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Award: &lt;/strong&gt;http://www.nsf.gov/awardsearch/showAward?AWD_ID=1041498&lt;/p&gt; &lt;p&gt;&lt;strong&gt;PIs &amp; CoPIs: &lt;/strong&gt;Thomas O&#39;Rourke, Amjad Aref, Andre Filiatrault, Harry Stewart, Sofia Tangalos&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Dates: &lt;/strong&gt;October 01, 2010 - December 05, 2013&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Organizations: &lt;/strong&gt;Cornell University, NY, United States&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Facilities: &lt;/strong&gt;Cornell University, NY, United States,    State University of New York at Buffalo, NY, United States&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Sponsor: &lt;/strong&gt;NSF - 1041498&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Keywords: --&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Publications: &lt;/strong&gt;&lt;br /&gt; Z.
