| 摘 要： | 本文研究了橡胶隔震垫与摩擦滑移板串联的组合式基础隔震层的动力特点和适用性,分析了整体倾覆力矩、支座竖向差异变形、上部结构竖向刚度等对串联的组合式隔震层的影响,以及组合式隔震层对上部结构扭转的影响.计算分析表明,由于摩擦滑移板竖向压应力的变化,引起隔震层水平动力性能产生变化,在设计中应予考虑.

| Abstract: | In this paper,the dynamical properties of base-isolation layer combined by rubber bearing and sliding-isolated bearing in series are studied.The effects of overturning moment,vertical difference deformation,and vertical stiffness of super-structure on isolation layer are analyzed,and the torsion effect of such isolated layer on super-structure is also analyzed.Calculated result shows,in such isolated layer,because of the vertical stress variation of sliding isolated bearing,the horizontal dynamic behavior of isolated layer is changed,this condition should be considered in design. |
