Abstract

This paper focuses on the goals of the second phase of the activities of the IASC-ASCE Structural Health Monitoring Task Group, involving the application of structural health monitoring techniques to data obtained from a four story steel frame structure tested July 19–21, 2000 at the University of British Columbia. Damage was simulated by removing bracing within the structure. An electromagnetic shaker and mass on the top floor of the structure were used to excite the structure. Accelerometers were placed throughout the structure to provide measurements of the structural responses. Three excitation cases were considered, including one ambient vibration level in which the shaker was turned off.
