Title: 144 DOF Dynamic Measurement from a 50' Full Scale Highway Sign Support Truss in Intact and Damaged Conditions (NEES-2011-1013)

Year Of Curation: 2012

Description: 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.
