A simplified analysis and vibration control to super‐high‐rise buildings
10.1002/tal.276.abs
This paper clarifies the following four points on the dynamic behavior of super‐high‐rise buildings of 700m high consisting of doubly symmetric frame‐tubes with or without braces. A simple and accurate analytical method presented by Takabatake (1996) is shown to be very useful for the preliminary design of such a mega‐structure. The building is replaced by an equivalent rod which may allow the main deformation field composed of longitudinal deformation, bending, transverse shear deformation, and shear‐lag. It is pointed out originally that, after the horizontal component of earthquake ground motion fades away, noticeable swell breaks out for a long time and that phenomenon is undamping. The serious phenomenon of swell increases remarkably in addition to the action of the horizontal component of an earthquake wave having a long period. The effect of soil–structure interaction on such a structure is discussed using a general analytical method proposed here. An epochal method both to reduce the dynamic response and to leave out the undamping swell after earthquake action is proposed and its effectiveness as a device for vibration control is demonstrated through the numerical computation.
