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

Year Of Curation: 2012

Description: 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.
