Lateral Load Behavior and Modeling of Shear-Dominant RC Walls for Performance-Based Design (NEES-2012-1131)

<p><strong>Title</strong>: Lateral Load Behavior and Modeling of Shear-Dominant RC Walls for Performance-Based Design (NEES-2012-1131)</p> <p><b>Year Of Curation: </b>2014</p> <p><b>Description: </b>The goals of the research are to develop and validate new modeling approaches appropriate for combined gravity and earthquake loads for buildings that utilize solid reinforced concrete walls. In particular, the project will study the structural performance of reinforced concrete walls, which are commonly used in the low-, medium-, and high-rise building construction, to develop new computer/numerical models and building code design guidelines. To accomplish these goals, approximately ten large-scale models of typical wall configurations will be tested under simulated earthquake loading in the Structural/Earthquake Engineering Research Laboratory at UCLA. The walls will be instrumented with high-resolution sensors to measure loads, stresses, strains, and their deformations. Test observations and the collected sensor data will be used to understand how damage accumulates and ultimately leads to collapse. Project will provide methodology to predict damage under moderate to intense ground shaking. The changes to building codes for the performance-based design for both new and existing buildings with these walls will be proposed.</p> <p><b>Award: </b>http://www.nsf.gov/awardsearch/showAward?AWD_ID=0825347</p> <p><b>PIs & CoPIs: </b>John Wallace</p> <p><b>Dates: </b>August 01, 2008 - July 31, 2012</p> <p><b>Organizations: </b>University of California, Los Angeles, CA, United States</p> <p><b>Facilities: </b>University of California, Los Angeles, CA, United States</p> <p><b>Sponsor: </b>NSF - CMMI - 0825347 </p> <p><b>Keywords: </b>Reinforced Concrete,Structural Walls,moderate-aspect ratio,nonlinear,cyclic</p> <p><b>Publications: </b><br /> Kristijan Kolozvari; Thien Tran; Kutay Orakcal; John Wallace, "15 WCEE P2"<br /> Thien Tran; John Wallace, "Research Report"<br /> Thien Tran; John Wallace, "15 WCEE P1"</p> <nb:citations></nb:citations>
