提出了一种在SIMULINK环境下对建筑结构基础滑移隔震体系进行仿真计算分析的新方法，给出滑移隔震结构隔震动力方程，分析了含滑移隔震层的剪切型多自由度串联体系模型，并给出模型的状态方程，根据模型状态方程在SIMULINK环境下建立了多质点滑移隔震结构的仿真程序，并将其应用到经平移后采用滑移隔震减震加固的江南大酒店工程中，计算结果与其他计算方法所得结论一致，证明了该方法对滑移隔震体系分析的正确性和有效性，基于SIMULINK的仿真分析方法还可以应用到土木工程其他主动与被动控制研究领域。

Seismic simulation of a sliding structure based on SIMULINK

A seismic simulation method for sliding structure based on SIMULINK environment is proposed. The dynamic equation of sliding layer is presented. The shearing type Multi Degree Freedom (MDOF) model in series system for the sliding building is analyzed, and then the model' state equation is given. According to this equation, a simulation program for Multi Particle model was completed in SIMULINK environment, and applied to Jiangnan Hotel Project, which had been shifted and reinforced through sliding isolation. This result proved its reliability and validity. This simulation method can also find its application in other active and passive controlling research of civil engineering.
