Japan largely depends on road traffic for transportation of people and commodities. Roads also play an important role in providing lifelines and supporting urban activity. Thus, after an earthquake. immediate repair and restoration are required. Estimating seismic damage to road facilities immediately after an earthquake would allow inspection of road facilities to be conducted efficiently. This paper discusses a system for estimating both ground vibration characteristics at random points and seismic damage to reinforced concrete pier. Both recorded accelerograms and observed damage to road bridge piers, which occurred during the 1993 Kushiro-oki Earthquake are used to check the validity of this system. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
