<p><strong>Title</strong>: Shake table study on the effect of diaphragm flexibility on out-of-plane dynamic stability of unreinforced masonry walls (NEES-2013-1195)</p> <p><b>Year Of Curation: </b>2014</p> <p><b>Description: </b>This project consists of an experimental study examining the out-of-plane stability under seismic loading of URM walls connected to flexible diaphragms. Five full-scale unreinforced solid clay brick wall specimens spanning one story were subjected to earthquake ground motions on a shake table. The top and bottom of the walls were connected to the shake table through coil springs, simulating the flexibility of the diaphragms. The apparatus allowed the wall supports to undergo large absolute displacements, as well as out-of-phase top and bottom displacements, consistent with the expected performance of URM buildings with unretrofitted timber diaphragms. Variables examined included diaphragm stiffness and wall height. </p> <p><b>Award: </b>Canadian Graduate Scholarship Canadian Seismic Research Network Natural Science and Engineering Research Council of Canada</p> <p><b>PIs & CoPIs: </b>Ken Elwood</p> <p><b>Dates: </b>February 24, 2012 - July 11, 2012</p> <p><b>Organizations: </b></p> <p><b>Facilities: </b>University of British Columbia, Vancouver, BC, Canada</p> <p><b>Sponsor: </b>Canadian Graduate Scholarship - (CGS-D) -</p> <p><b>Keywords: </b>out-of-plane,shake table,unreinforced masonry wall,flexible diaphragm</p> <p><b>Publications: </b>"Out-of-Plane Dynamic Stability of Unreinforced Masonry Walls Connected to Flexible Diaphragms" </p> <nb:citations></nb:citations>
