摘要:
利用有限元方法对新型约束橡胶隔震支座进行有限元分析,通过竖向单调加载的数值模拟,分析竖向荷载作用下支座的竖向力学性能和极限承载能力。通过研究不同形状系数对橡胶支座竖向力学性能的影响,结果显示:相比于传统的叠层橡胶隔震支座,约束橡胶隔震支座具有更低的竖向刚度,并具有更高的竖向承载力,能够提升结构的竖向减振效率。
Abstract:
The vertical mechanical properties of a new type of confined seismic isolation rubber bearings are studied,and the rubber bearings are analyzed by using the finite element method.Through the numerical simulation of the vertical monotonic loading,the vertical mechanical properties and ultimate bearing capacity of the rubber bearings under the action of the vertical load are analyzed.In addition,the effects of different shape factors on the vertical mechanical properties of the rubber bearings are studied.The results show that compared with the traditional laminated rubber bearings,the confined rubber bearings have lower vertical stiffness,while still possessing higher vertical bearing capacity,can effectively improve the damping capacity of the isolation device in vertical direction.
