摘要： 分析了设锚栓的加劲板式橡胶支座在橡胶垫与锚栓接触前后的水平刚度.与支座变形相一致,进行了接触问题的近似分析,得到了一个便于计算机编程的刚度函数算式.一个4柱支承大跨度预应力浅网壳结构的有限弹性变形分析表明,锚栓对计算结果影响较大.

关键词: 空间结构； 静力分析； 加劲板式橡胶支座； 水平刚度；

Abstract: The paper analyzes the horizontal stiffness of laminated rubber bearing with anchor bolts when the rubber pad is close to the bolts. In agreement with the bearing deformation, approximate contact analysis is made, and a simplified stiffness function formula that is benefit to computer programming is concluded. Finite elastic deformation analysis of a four-column-supported prestressed shallow lattice shell roof shows that the bolts have influence upon the computed results more significantly.

Key words: spatial structures； laminated rubber bearing； static analysis； horizontal stiffness；
