Abstract

Structural health monitoring (SHM) is a promising field with widespread application in civil engineering. However, many SHM studies apply different methods to different structures, often making side-by-side comparison of the methods difficult. This paper details the first phase in a benchmark SHM problem organized under the auspices of the IASC-ASCE Structural Health Monitoring Task Group. The scale-model structure adopted for use in this benchmark problem is described. Then, two analytical models based on the structure — one a 12DOF shear-building model, the other a 120DOF model, both finite-element based — are given. The damage patterns to be identified are listed as well as the types and number of sensors, magnitude of sensor information, and so forth. More details are available on the Task Group web site at wusceel.cive.wustl.edu/asce.shm/ .

Additional Information:The authors wish to thank the other members of the IASC-ASCE SHM Task Group for their assistance, suggestions, and cooperation in the development of this benchmark problem; particularly: Dionisio Bernal (vice-chair, Northeastern Univ.), Raimondo Betti (Columbia Univ.), Joel P. Conte (UCLA), Shirley J. Dyke (Wash. Univ. St. Louis), Sami F. Masri (Univ. of Southern California), Andrew Smyth (Columbia Univ.), and Carlos E. Ventura (Univ. of British Columbia). Thanks especially to Prof. Ventura for the photograph of the UBC frame, and to Prof. Conte for assistance in calibrating the finite element models described herein.
