| 摘 要： | 探讨了橡胶隔震支座在压缩剪切状态下竖向刚度计算理论,对不同参数的橡胶支座在压缩剪切变形状态下的竖向刚度性能进行试验,并对不同计算式所得的偏压竖向刚度值进行比较分析。得出在全面评价橡胶隔震支座特性时,单纯压缩竖向刚度不足以全面反映橡胶隔震支座的竖向压缩性能的结论。

| Abstract: | In this paper,the computation theories for vertical rigidity of bridge seismic isolation rubber bearings in a state of compression and shear deformation are discussed.The tests for vertical rigidity properties of the bearings with different parameters in the same state as mentioned above are performed and the vertical rigidity values of biasing compression obtained by different equations are analyzed and compared.Finally,conclusions are generalized that the vertical rigidity of pure compression is not enough to completely reflect the vertical compression properties of the bearings when the properties of the bearings are evaluated in an all-round way. |
