N2 - In this study, we extracted all seismic ground motions of the maximum in ground level acceleration 300 (cm/s2) and more from 1996 to 2011 by using the K-NET. From the ground level acceleration data, we formulated the relationship between the peak response velocity and the peak velocity of the ground excitation. Then, we obtained the relationship between the collision velocity and the height of the vertical gap between adjacent girders. By using two obtained relationships, we did the risk evaluation for the car trafficability by the damage of the girder ends due to severe earthquakes. As a result of the risk evaluation, it is understood that the return period that we can't drive a car at the speed of 80 km per hour and more about 5% in the next 30 years due to a severe earthquake in Shizuoka City.
