为了深入研究摩擦摆(FPS)隔震网壳结构的抗震性能,将这种隔震装置用于双层球面网壳结构的层间隔震。首先介绍了FPS支座的减振原理,建立了层间隔震网壳结构的运动方程。通过层间隔震双层球面网壳屋盖模型在三向地震作用下的时程分析,全面考察了屋盖结构、支承结构和FPS支座的地震响应。研究结果表明,FPS支座有利于保护整体结构,可有效地应用于球面网壳屋盖结构的层间隔震。
In order to further study the seismic behavior of FPS reticulated shell structure, this isolation device is applied to the isolation of double-layer spherical reticulated shell structures. Firstly, the damping principle of FPS bearing is introduced and the equations of motion of the reticulated-shelled reticulated shell are established. Through the time-history analysis of the double-shelled double-layer reticulated dome model under the three-direction earthquake, the seismic response of roof structure, supporting structure and FPS bearing is comprehensively investigated. The results show that the FPS support is beneficial to the overall structure protection and can be effectively applied to the isolation of the dome of the spherical reticulated shell.
