文章为了研究端部固定转角对叠层橡胶支座水平刚度的影响，采用直接积分法，推导了在压剪作用下叠层橡胶支座带有端部固定转角参数的水平刚度方程，并根据端部固定转角情况将水平刚度方程分成4类，通过算例分析了端部固定转角、竖向荷载及水平荷载等参数对叠层橡胶支座水平刚度的影响。结果表明：端部固定转角和水平荷载对叠层橡胶支座水平刚度的影响具有方向性效应；在端部固定转角和水平荷载一定时，叠层橡胶支座水平刚度随着竖向荷载的增大而降低；为了满足工程需求，根据端部固定转角与初始变形和初始水平刚度的变化情况，端部固定转角宜控制在0．25％以内。

In order to analyze the effect of end fixed angle on the horizontal stiffness of the laminated rubber bearing ,the equation of horizontal stiffness of the laminated rubber bearing with the end fixed angle was derived by the direct integration method under the vertical force and share force .Four con-ditions were sorted considering the different end fixed angle and a numerical example was given to ana-lyze the effect of the parameters of end fixed angle ,horizontal force and vertical force on the horizon-tal stiffness of the laminated rubber bearing .The results are as follows :the end fixed angle and hori-zontal force have a directional effect on the horizontal stiffness of the laminated rubber bearing ;w hen the end fixed angle and horizontal force are given , the horizontal stiffness of the laminated rubber bearing decreases with the increase of the vertical force ;the end fixed angle should be less than 0.25%to satisfy the engineering requirement based on the initial displacement and initial horizontal stiffness .
