Dynamic Measurements from a Laboratory Truss in Healthy and Damaged Conditions (NEES-2011-1031)

<p><strong>Title</strong>: Dynamic Measurements from a Laboratory Truss in Healthy and Damaged Conditions (NEES-2011-1031)</p> <p><strong>Year Of Curation: </strong>2012</p> <p><strong>Description: </strong>A 5.6 m long, 14-bay, three-dimensional truss structure has been tested at the Smart Structures Technology Laboratory(SSTL) of the University of Illinois at Urbana-Champaign (UIUC). This specimen was designed to provide a testbed for testing and validation of existing damage detection methods. The truss members are steel tubes with an inner diameter of 1.09 cm and an outer diameter of 1.71cm. The joints of the elements are specially designed so that the truss member can be easily removed or replaced to simulate damage without dissembling the entire structure. The truss is excited vertically by a Ling Dynamic Systems permanent magnetic V408 shaker that can generate a maximum force of 20 lbs with a dynamic performance ranging from 5 Hz to 9000 Hz. PCB high sensitivity piezotronics accelerometers (model 353B33) are used to measure the response of the structure.</p> <p><strong>Award: </strong>http://www.nsf.gov/awardsearch/showAward?AWD_ID=1035748</p> <p><strong>PIs & CoPIs: </strong>Yong Gao, Billie Spencer, Zhuoxiong Sun</p> <p><strong>Dates: </strong>January 01, 2001 - March 31, 2011</p> <p><strong>Organizations: </strong>University of Illinois at Urbana-Champaign, IL, United States</p> <p><strong>Facilities: </strong>University of Illinois at Urbana-Champaign, IL, United States</p> <p><strong>Sponsor: </strong>NSF - CNS - 1035748</p> <p><strong>Keywords: </strong>accelerometers, monitoring, truss</p> <p> </p> <nb:citations></nb:citations>
