英文摘要	In order to analyze the influence of boundary conditions on horizontal stiffness of the laminated rubber bearings, the equations of horizontal stiffness of the laminated rubber bearings under the vertical load and share force were derived by the direct integration method using the shear-bending model. Four boundary conditions were proposed. The influence of the rotational constraint parameters k0 and kh and vertical load p on horizontal stiffness of the laminated rubber bearings were mainly analyzed using a case. The values of equation derived for different boundary conditions were compared. The results show that the boundary conditions have great influence on horizontal stiffness of the laminated rubber bearings, and when the rotational constraint parameters k0 and kh and vertical load p are the same, the horizontal stiffness is largest for the first boundary condition (k0≈∞ and kh≈∞), and is smallest for the forth boundary condition; when the boundary condition is the same, other horizontal stiffness increase with the increasing of the rotational constraint parameters k0 and kh and are approximate to the first boundary condition. All decrease with the increasing of the vertical load p.
