Setting friction pendulum bearings (FPB) at the top of central columns may be a good strategy to reduce the stations’ seismic responses. In this paper, the FPB is simulated in a detailed manner. The seismic reduction effectiveness of the FPB is studied with the three-dimensional dynamic time history analysis method. It is found that FPB can effectively reduce the maximum shearing force of the central columns and slightly reduce the maximum bending moment. It is stated that FPBs are also effective in the underground station structures.

地下车站结构摩擦摆轴承的减震效果

在中心柱顶部设置摩擦摆轴承 (FPB) 可能是减少台站地震响应的好策略。在本文中，对 FPB 进行了详细的模拟。采用三维动态时程分析方法研究了FPB的减震效果。研究发现，FPB可以有效降低中心柱的最大剪力，并略微降低最大弯矩。据称，FPB 在地铁站结构中也很有效。
