【Abstract】 The vibration phenomena of structure is obvious everywhere. To avoid some induced disaster effectively, the vibration’s control technology is used frequently. One two-floor rigid frame is been used as a simple example, in order that the basic thought of vibration’s control is understood easily. Considering the frame’s horizontal vibration, two kinds of control’s design thoughts, i.e. base isolation structure and turned mass damper structure, are derived step by step from the direct solution of frame’s dynamical equation.更多还原
