Abstract: Fukuro bridge, a stone arched bridge, is of about 17m in length constructed in about 1655, and, is one of which automotive can pass of 2 bridges in stone bridge group cultural assets of Nakajima River. In the vicinity of a basal part of a ring stone of the bridge, isolation, cracked and some other deterioration were confirmed. It is increase of traffic density of automotive that was nominated for one of the causes. Therefore, in this research, We performed the detection of a natural frequency by ambient vibration, investigation of quantity of opening and shutting of seam region by vehicle traffic, and furthermore, examination to relate to safety for the purpose of investigating a vibration characteristic of the bridge for vehicle traffic. For realizing automated measurement, I made a program with LabVIEW and applied to this measurement.
