摘要：
A sliding isolator is an isolation device of steady performance and simple structural configuration. This paper introduces a novel sliding bearing with friction interface coated with molybdenum disulfide. To study the friction character of the sliding isolator and the isolation effect of parallel isolated buildings with sliding isolators, a quasi-static test, a real time hybrid simulation (RTHS) and a numerical simulation were performed. The results of the quasi-static test showed the friction coefficient of the sliding bearing correlated with horizontal loading frequency and pressure. RTHS, with the sliding bearing as the experimental substructure, the lead rubber bearings and the upper structure as the numerical substructure, the responses of the sliding bearing under earthquakes were studied. Then the RTHS results were compared with finite element analysis results to evaluate isolation effect. It is concluded that the parallel isolated structure with sliding isolators and lead rubber bearings has desirable isolation effect. © 2017, Editorial Office of Journal of Vibration and Shock.
