摘要
传统的建筑结构抗震设计方法是利用结构本身物理特性来保证结构具有一定的强度、刚度和延性。在强震地区或结构所受的动力荷载超过某种程度后,这种抗震手段很难达到预期的效果。TMD技术是确保地震过程中建筑结构安全性的另一种有效方法之一。本文根据振动控制理论,推导运动方程,建立仿真模型,设计TMD系统各参数。最后,以25层建筑结构为实例,计算结果表明本文方法减震效果明显。
Traditional anti-seismic method in the realm of building structures used to the physical characteristics of the structure itself to ensure that the structure has a certain strength, stiffness and ductility. This method is usually difficult to achieve the desired effect when the structure is exposed to the power loads or in the violent earthquake areas. TMD technology is another effective way to ensure the security of the building in the process of earthquake. In the paper, the system motion equations are derived and the simulation models are established, as well, the parameters of the TMD are obtained based to the theory of vibration control. Finally, the 25-story building is used as a example as well as the calculated results show that the anti-seismic effect is very effective.
