英文摘要	Taking the serial seismic isolation system, which consists of laminated rubber bearing mounted on top of basement column, as the investigated subject, the vertical load bearing capacity of serial isolation system with independent column are compared with that of the serial isolation system with link beam on top of basement column. 1 FEM model of serial isolation system with independent column and 3 models of serial isolation system with link beam of different beam-column linear stiffness ratios are established using nonlinear FEM Software ABAQUS, and a monotonic loading test of the serial isolation system is numerically simulated combined with horizontal loading of different initial values. The vertical-horizontal loading curve of serial isolation system are quantitatively compared for different initial values of horizontal load and different values of beam-column linear stiffness ratios, and the effect of these two factors on the ultimate vertical loading and on the damage pattern of serial isolation system are investigated. The result shows that the increase of vertical load bearing capacity of serial isolation system is directly proportional to beam-column linear stiffness ratios, and is inversely proportional to initial value of horizontal load. However, the relative degree of increase of vertical load bearing capacity is roughly proportional to initial value of horizontal load. However, the relative degree of increase of vertical load bearing capacity is roughly proportional to initial value of horizontal load.
