Shaking table tests of 'masugumi' used in traditional wooden architectures

For the purpose of evaluating the seismic performance of masugumi, which is one of the most important architectural components in ancient Japanese wooden buildings, the shaking table tests using a full-size masugumi component were carried out. From the comparison of shaking table tests with static lateral loading tests, which had been carried out before, it was found that the initial stiffness obtained from shaking table tests was in agreement with the one obtained from static loading tests. In this paper, the rotating angle and slip deformation of each element of masugumi are also discussed.
