带限位装置的摩擦隔震结构动力特性及地震反应分析
Dynamic Characteristics and Earthquake Response Analysis of Structures Supported on Slide-limited Friction Base Isolation System
摘要
Abstract
This paper presents a new type base isolation system, i.e. the slide-limited friction base isolation system (S-LF). Based on this system, the harmonic and subharmonic periodic responses of S-LF subjected to ground harmonic motions are investigated by using the Poincare Map. Dynamic response of sliding structure subjected to earthquake ground motions are calculated with a high order precise direct integration method, and the numerical results are presented in maximum acceleration response spectra of superstructure and maximum sliding displacement response spectrum form. In comparison with isolation effects of pure-friction base isolation system (P-F) and resilient-friction base isolating system (R-FBI), it shows that the isolation characteristic of S-LF is superior to those of P-F and R-FBI. Finally, through analyzing an engineering example, it is observed that the distribution of maximum shear force between floors and maximum absolute acceleration of each floor of the sliding structure under earthquake ground motions are quite different from those of the traditional structures.关键词
