建筑物滑动隔震试验研究及计算分析

Experimental Study and Calculation Analysis of the Sliding-Type Base Isolation Structures

本文进行了振动台上的刚体、单层模型及两层模型滑动隔震试验。提出了具有限位装置的滑动隔震体系的计算模型、运动方程及滑动判别条件,并编制了隔震及不隔震体系地震反应的计算程序。计算结果与试验结果符合较好。对隔震规律进行了分析。

The sliding-type base isolation tests of the rigid body and the one-sto- ried model and the two-storied model are carried out on the shaking table. The mathematical model and the equations of motion and the sliding discrimination condi- tions of the sliding-type base isolation system with displacement-restricting devices are proposed. According to these theories, the computer program calculating the earthquake reaction of the structures with and without the sliding-type base isolation is completed. The results of calculation accord with the experimental results considerably, and the regularies of the sliding-type base isolation are analysed.
