Abstract
The cross section of box culverts for road has recently become large and been complicated, which makes it difficult to evaluate the seismic limit states of these box culverts. This research focuses on the limit states of the box culverts for the seismic performance design based on a series of cyclic loading tests for 1/3 scaled models. The failure mechanism of the box culverts under cyclic loading was observed during the tests, where the damage developed on both outside and inside faces was monitored so as to discuss the seismic limit states of the box culvert structure. Furthermore experimental results of the cyclic loading tests for the box culverts were simulated by the two-dimensional frame analysis. An applicability of the frame analysis was discussed through a comparison of analytical results with experimental observations.
