Abstract

 The forced vibration test of RC slab by using a portable shaker was proposed. The first resonance frequency was given by the vibration test in thickness direction at each measured point. In the vibration tests of the RC beam specimens with a innner void, resonance frequency was clearly decreased in the void part. Also, it was shown that the resonance frequency of the crack part decreased in the vibration test of RC slab sampled from practical road bridge. Moreover, in the experimental result of the measurements on a highway bridge in service, it was shown that the proposed metod was useful for non-destructive testing of RC slab under traffic loading.
