STUDY ON AN INNOVATION TENSILE-RESISTANT DEVICE FOR LAMINATED RUBBER BEARING

Base isolation is restricted on large aspect ratio structure due to the fact that the tensile ability of the laminated rubber bearing is poor.An innovation tensile-resistant device for laminated rubber bearing(TRDLRB) is proposed by way of taking advantage of compressive ability to resist the tensile force.Nonlinear dynamic analysis of an isolated high-rise building under severe earthquake loading is performed in this paper to study the effects of the TRDLRB.The analysis results show that,the TRDLRB is feasible because of the simple in both design and manufacture,and the vertical displacement of the isolation layer is reduced despite the tensile force caused by superstructure using TRDLRB.The study also shows that the dynamic response of the isolated high-rise building is reduced remarkably and the tensile ability of the isolation layer is improved significantly.
