For the purpose of an advancement of the evaluation technology for earthquake resistance of the nuclear plants, we paid attention to the support structures of component system of the nuclear plants generally designed as fixed/pinned boundaries. The specimens were prepared and static cyclic load experiments and hybrid earthquake response experiments were carried out for them. From the experimental results, we got some knowledge about the basic load resistant characteristics and the damage modes of those support structures.
