| Research Abstract |
It was theoretically verified that the transition from rocking to rotational motion about vertical axis, concerning cylindrical columns on the base of traditional wooden structures subjected to horizontal earthquake, was an unknown critical behavior. The motion has been observed in a previous experiment. The occurrence of the attracted rotational behavior can be described by the condition for the existence of non-trivial solution to a homogenous equation in the direction perpendicular to an exciting force. Consequently theoretical development to explain the transition to the movements of cylindrical columns was valid. These results contribute to earthquake resistant design for traditional wooden structures including important cultural properties.
