摘要
根据新修订颁布的建筑抗震设计规范，以铅心橡胶隔震系统为例，介绍了基础隔震的力学特性和分析模型，以及基础隔震结构的计算方法。利用SAP2000大型有限元程序，对一工程实例进行了时程分析。结果说明基础隔震装置能够有效地降低地震对结构的作用，对工程设计的具体应用具有参考价值。
According to the code for seismic design of buildings being published recently, mechanical behavior and analytic model of base isolation are presented as an example of isolation system with lead - rubber. And computational methods are also presented. An example is analyzed in time history analysis with SAP2000 finite-element analysis program. The results show that the action on structure of earthquake can be reduced by base isolation, which has an engineering sense.
