摘要
讨论了橡胶垫基础隔震建筑的地震作用简化计算 .其中上部结构采用层间剪切模型 ,隔震系统采用双线性恢复力滞回特性曲线 .考虑设防烈度、场地类别、隔震系统的阻尼比、刚度及其折减系数等因素的影响 ,将相应的地震记录输入分析模型进行时程分析 ,对时程分析的结果 (基底剪力、基底位移、地震作用沿高度的分布 )进行回归分析 ,提出了橡胶垫基础隔震建筑的地震作用简化计算方法 .该方法的优点是计算简单且适用于双线性隔震系统 .
A simplified calculation method is discussed, in which the superstructure is idealized as a shear type model. Meantime the isolated system adopts the double linear resilience curve. The practical calculation formulas of the earthquake action are put forward, which consider the correlation of the factors such as parameters of the earthquake, parameters of the structure and the dynamic characteristics parameters of the structure. The calculation of the method is simple and the method is suitable for the isolated system with the double linear resilience curve.
