This paper discusses the dynamical characters of the RC mega-sub controlled structure. It is concluded that the deformation and the acceleration of vibration-absorption megaframe structure can be well reduced under the windward pulsoting wind load, through choosing the reasonable the member parameter and the accessional columns stiffness of the structure. So the safety of the structure is enhanced, and the comfortable need is satisfied. So the new mega-sub controlled structure is a kind of ideal super tall building structure configuration, it will have the bright future.
