Abstrait:

In order to investigate the natural vibration characteristics of a steel composite girder bridge before and after replacement of the RC slab, micro-tremor measurement tests after traffic passing were conducted. Here, 51 high-sensitive servo-type vibration meters and a wireless LAN system were used to measure the vibration acceleration of the bridge. The results obtained from this study were as follows: 1) natural vibration frequencies and modes can be appropriately evaluated by conducting the proposed micro-tremor measuring test; and 2) since natural vibration frequencies were increased and all vibration modes were improved to be more symmetrical and/or

anti-symmetrical, it is seen that the bridge stiffness is upgraded by replacing the RC slab.
