Research on friction pendulum isolation design and parameter optimization of a frame-tube structure
Rubber bearing isolation technology has always occupied the mainstream position in China's building isolation structure.In recent years,friction pendulum isolation bearing has gradually attracted the attention of engineers and technicians because of its characteristics of friction energy dissipation and high self-centering ability.In this paper,a high-rise frame tube office building in 8 degree area is taken as an example to analyze the isolation design of friction pendulum bearing,and compared with the rubber isolation bearing scheme.The results show that the horizontal damping coefficients of the two isolation schemes are similar,and both of them can achieve significant isolation effect.However,the friction pendulum scheme has smaller isolation displacement under large earthquakes and has certain advantages.This study further optimizes the parameters of friction pendulum bearing including curvature radius and friction coefficient,which can provide reference for the isolation design of friction pendulum bearing.
