First damaged cases of pipes attached to road bridges in Tohoku Earthquake in 2011 are analyzed using pipe attributes and estimated seismic motion data. Seismic motion data was estimated (250m mesh size) by simple kriging method using seismic observation point data. From the damaged cases analysis, it is confirmed that the spectral-intensity is larger, damaged ratio of pipe attached to road bridge is higher. On the other hand, clear relationship between PGA (Peak Ground Acceleration) and damaged ratio did not show. In point of structure of the road bridge that pipes are attaching, the length of road bridges is longer, the damage ratio of pipes attached to road bridges is higher. In damage mode analysis, separation of pipe joints was most major damage mode. In this paper, the result of these basic analyses and result of site investigation are shown.
