摘要
提出了一种新型基础隔震模型 ,即带限位装置的摩擦隔震系统 (S- L F) ;基于此隔震模型 ,利用 FGN法 ,并结合 Floquet理论研究了地面谐运动下 S- L F的主谐、次谐运动特性 ;通过与纯摩擦滑移隔震系统 (P- F)和恢复力摩擦隔震系统 (R- FBI)的比较表明 ,S- LF的隔震性能优于 P- F和 R-
This paper presents a new type base isolation system,i.e.,slide limited friction base isolation system(S LF).Based on this system,harmonic and subharmonic periodic response of S LF subjected to harmonic motions is investigated by using Fourier Galerkin Newton method with Floquet theory.By comparison of isolating effects of S LF,pure friction base isolation system(P F) and resilient friction base isolation system(R FBI),it shows that the isolating capability of S LF is superior to P F and R FBI.
