Abstract

The floor location effect in the damage detection process is discussed on a 3 storey frame, which is compared to a numerical simulated vertical cantilever beam to illustrate the results. It is concluded that the effect of the floor location is insignificant on the frequency trend while the damage ratio varying, and it is significant while the damage location varying. The effect of the floor location is less while the damage locates nearer the floor location. The basic trend still exists while the damage location varying in the further investigation, but it may be covered by the local waves in the general illustrations. It is considered that the effect would be more significant to the unsupervised methods.
