144 DOF Dynamic Measurement from a 50' Full Scale Highway Sign Support Truss (NEES-2011-1013)

<p><strong>Title: </strong>144 DOF Dynamic Measurement from a 50' Full Scale Highway Sign Support Truss in Intact and Damaged Conditions (NEES-2011-1013)</p> <p><strong>Year Of Curation: </strong>2012</p> <p><strong>Description: </strong>A 17.4 m long, 11-bay, three-dimensional highway sign support truss structure was tested at the Robert L. and Terry L. Bowen Laboratory for Large-Scale Cvil Engineering Research of the Purdue University. The truss is 17.04m long, 1.83m wide and 1.98m high. All members have cylindrical a cross-section. The truss is made of aluminum alloy (6061-T6). The truss studied here was previously mounted over interstate I-29 near Sioux City in Iowa as a sign support to display route information. The truss consists of 4 space frames connected by bolted joints and 2 planar frames for end supports. Two sections of the four space frames were assembled at the Bowen laboratory for testing.</p> <p><strong>Award: </strong>http://www.nsf.gov/awardsearch/showAward?AWD_ID=1035748</p> <p><strong>PIs & CoPIs: </strong>Shirley Dyke, Sriram Krishnan, Zhuoxiong Sun</p> <p><strong>Dates: </strong>April 04, 2011 - July 26, 2011</p> <p><strong>Organizations: </strong>Purdue University at West Lafayette, IN, United States</p> <p><strong>Facilities: </strong>Purdue University at West Lafayette, IN, United States</p> <p><strong>Sponsor: </strong>NSF-CNS-1035748</p> <p><strong>Keywords: </strong>vibration testing, large scale testing, accelerometer, wireless sensor network, shaker, hammer, damage localization, damage detection, shm, truss, 3D model</p> <p><strong>Publications: </strong>N/A</p> <nb:citations></nb:citations>
