竖向隔震的机理研究和装置设计
|
摘要
针对空间网格结构的复合隔震,重点研究其竖向隔震机理.首先建立了支座竖向刚度、激励特征频率与隔震系数间的关系,验证了竖向隔震的可行性;结合支座的应用条件,建立了支座竖向刚度计算公式,为支座的竖向隔震装置设计提供了依据;并给出了弹簧隔震装置的设计方法.
Focused on 3-dimensional seismic isolation for latticed roofs,the mechanism and device in vertical direction of the bearing are discussed.Firstly,absolute isolation effectiveness (S_(ic)) is introduced.Based on S_(ic),the relationship between vertical stiffness and characteristic frequency of input excitations is established, and it verifies that means of seismic isolation in vertical direction is realizable.Then the formula for stiffness in vertical direction is developed.Finally,some parameters related to the design of springs are analyzed,and the practical measures are established as well.
