Abstract
This paper presents a recent shake table experiment on a 4-story steel frame with predictable damage. The yielding of column in the first story was produced to represent damage and the deterioration changed the structural properties. Using acceleration measurement, the damage can be obtained and compared with visual inspection of the structures. In addition, a structural damage detection algorithm based on time-frequency representation was validated based on the experimental data.
