| Research Abstract |
Present seismic design for highway bridge piers is specified based on the structural behavior in the single directional seismic excitation. In this study, rational seismic design is proposed by conducting hybrid test using actual earthquake excitation data in horizontally two directions. As a result, it is found that there is no much difference in the structural behavior between one and two directional earthquake excitations on ground level 1(hard) and 2(medium). However, the experimental pier models under two directional loading on ground level 3, where most cities in Japan locate, failed though they did not failed in one directional loading. Numerical analysis model for the hybrid test had developed as well.
