| 摘 要： | 为研究罕遇地震下复合隔震村镇建筑的地震响应特征及设计参数，采用ABAQUS有限元软件建立了复合隔震结构、滑移隔震结构、砂垫层隔震结构以及传统的砌体结构四种模型，通过对比4种模型在不同滑移层摩擦系数及不同地震烈度下的加速度、位移及底部剪力等动力响应差异，得出复合隔震体系的地震响应特征及主要设计参数。结果表明:复合隔震体系具有最优的隔震效果，且滑移层摩擦系数越小，地震烈度越大，隔震效果越好。根据预设40%隔震率的要求，确定出不同抗震设防烈度区的滑移层摩擦系数取值范围。

| Abstract: | In order to study characteristics and design parameters of composite isolation system for rural buildings underrare earthquake, four different models of composite isolation structure, sliding isolation structure, sand cushion isolation structure and traditional masonry structure were established by the finite element software ABAQUS. Then, by comparing the dynamic response differencesof acceleration, displacement and base shear of each model under different friction coefficient of sliding layer and seismic intensity, the seismic response characteristics and main design parameters of composite isolation system were obtained. The results show that the composite isolation system has the best isolation effect, furthermore, the smaller the friction coefficient of sliding layer and the greater the seismic intensity, the better the isolation effect of composite isolation system will be obtained. According to the preset isolation rate of 40%, the value range of friction coefficient of the sliding layer in different seismic intensity zones was determined. |
