Full scale shaking table tests of exposed type column bases are carried out. Parameter of the specimen is thickness of the base plate. Hysteresis rule of the column base with thick base plate, weak anchor bolt type column base, is expected to be of slip-type, since its plastic deformation is brought by monotonic tensile deformation of the anchor bolts. There are many research works of weak anchor bolt type column bases by static experiments. One of the purpose of this shaking table experiment is to prove the applicability of the statical research works to predict the dynamic responses of exposed type column bases. On the other hand, the hysteresis rule of column base with thin base plate, weak base plate type column base, is expected to be spindle shape due to the plastic deformation of the base plate under repeated bending. Evaluating the hysteretic behavior of weak base plate type column base is another purpose of this experiment. From experimental results, following conclusions were obtained. 1. The research works of weak anchor bolt type column bases obtained by the static experiments are applicable to the dynamic behaviors. 2. The energy absorbing capacity of weak base plate type column base can be greater than that of weak anchor bolt type column base.
