Seismic Performance Assessment and Retrofit of Non-Ductile RC Frames with Infill Walls (NEES-2007-0422)

<p><strong>Title</strong>: Seismic Performance Assessment and Retrofit of Non-Ductile RC Frames with Infill Walls (NEES-2007-0422)</p> <p><b>Year Of Curation: </b>2012</p> <p><b>Description: </b>The data presented here is from a collaborative research project carried out by researchers from the University of California at San Diego, Stanford University, and the University of Colorado at Boulder. The research objectives were two-fold. One was to develop rational and reliable analytical methods, such as refined computational models and simplified analysis methods, for assessing the seismic performance of masonry-infilled RC frames, and the other was to develop effective seismic retrofit techniques to strength and improve the performance of non-ductile RC frame structures infilled with unreinforced masonry. For the latter objective, a retrofit technique using an Engineered Cementitious Composite (ECC) overlay on unreinforced masonry infill walls was developed and evaluated. In one shake-table test specimen, the effectiveness of using a Glass Fiber Reinforced Polymeric (GFRP) overlay was investigated as well. The retrofit schemes and analytical tools were validated with experimental data obtained from small- and large-scale frame specimens representing 1920-era construction in California. These tests are summarized as follows and a complete set of the test data is available at this site.</p> <p><b>Award: </b>http://www.nsf.gov/awardsearch/showAward?AWD_ID=0530709</p> <p><b>PIs & CoPIs: </b>Benson Shing, Sarah Billington, Kaspar William</p> <p><b>Dates: </b>October 09, 2006 - October 12, 2010</p> <p><b>Organizations: </b>Stanford University, CA, United States,    University of California, San Diego, CA, United States,    University of Colorado at Boulder, CO, United States</p> <p><b>Facilities: </b>Stanford University, CA, United States,University of California, San Diego, CA, United States,University of Colorado at Boulder, CO, United States</p> <p><b>Sponsor: </b>NSF - 0530709 </p> <p><b>Keywords: </b>non-ductile RC frames, masonry infill, seismic performance, seismic retrofit, seismic strengthening</p> <p><b>Publications: </b><br /> "Numerical Analysis of Masonry-Infilled Reinforced Concrete Frames Subjected to Seismic Loads and Experimental Evaluation of Retrofit Techniques"<br /> "Analytical and Experimental Study of Seismic Performance of Reinforced Concrete Frames Infilled with Masonry Walls"<br /> "Numerical Analysis of Masonry-Infilled Reinforced Concrete Frames Subjected to Seismic Loads and Experimental Evaluation of Retrofit Techniques" </p> <nb:citations></nb:citations>
