摘　　要：将叠层橡胶支座和Ｒ／Ｃ柱的串联机构作为隔震系统的做法在实际工程中已有应用，但至今尚无规范化的设计计算方法。该文将橡胶支座简化为考虑Ｐ－Δ效应的剪弯型竖杆、Ｒ／Ｃ柱简化为弯曲型竖杆，建立了橡胶支座和Ｒ／Ｃ柱串联隔震系统的分析模型，推导了水平刚度系数的实用计算公式，并对典型参数的影响进行了分析。The serial isolation system consisting of laminated rubber bearing and R/C column has been applied in practical building,but without the corresponding codes for calculation and design yet. An analytic model of the serial system that rubber bearing is modeled as the shear bending type vertical bar considerating of P Δ effect and R/C column is modeled as the bending type vertical bar is set up in the paper. The practical calculation formulas are deduced and the stability is analyzed. Some influences of typical parameters are also given and analyzed.
