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.
