An Experimental and Analytical Study of the Earthquake Response of R/C Frames with Yielding Columns (NEES-2011-1063)

<p><strong>Title</strong>: An Experimental and Analytical Study of the Earthquake Response of R/C Frames with Yielding Columns (NEES-2012-1063)</p> <p><b>Year Of Curation: </b>2012</p> <p><b>Description: </b>The structural framing systems permitted by existing design codes are in part a product of scientific scrutiny as well as a matter of subjective opinion. The use of reinforced concrete frame structures with girders flexurally stronger than the columns is avoided in seismic areas because of fear of inadequate response. The professional community, through building codes, prohibits the use of such a framing system. It is feared that when all the columns at a story yield, an elastoplastic mechanism will be formed leading to imminent. Codes also aim to prevent column strength decay under load reversals, joint failures, and shear failures of the columns. However, reinforced concrete structures exhibit post-yield stiffness under dynamic loading, rendering an elastoplastic mechanism unrealistic. This reserve stiffness may be used to limit drift to acceptable levels.</p> <p><b>Award: </b>NSF CEE 81-14977</p> <p><b>PIs & CoPIs: </b>Mete Sozen, Arturo Schultz</p> <p><b>Dates: </b>November 24, 1982 - June 21, 1984</p> <p><b>Organizations: </b>University of Illinois at Urbana-Champaign, IL, United States</p> <p><b>Facilities: </b>University of Illinois at Urbana-Champaign, IL, United States</p> <p><b>Sponsor: </b>NSF CEE - 81-14977</p> <p><b>Keywords: </b>Shake Table,Yielding Columns, Strong-Beam Weak-Column, Concrete frame</p> <p><b>Publications: </b>"An Experimental and Analytical Study of the Earthquake Response of R/C Frames with Yielding Columns"</p> <nb:citations></nb:citations>
