【提要】  总结了地震剪力与地震层间位移比、剪切刚度比、剪弯刚度比在《建筑抗震设计规范》和《高层建筑混凝土结构技术规程》中的定义和计算方法。为了帮助SATWE软件用户正确地选择刚度比的设置，结合一个框支剪力墙结构算例，探讨这三种刚度比在SATWE软件里的适用范围及实现过程，并提出在运用SATWE软件进行结构计算时应注意的问题。

Abstract:The definitions and calculation methods of seismic force and story drift ratio,shear stiffness ratio and shearbending stiffness ratio defined in the Code for seismic design of buildings and Technical specification for concrete structures of tall building,are summarised.In order to help the SATWE users to select the stiffness ratio correctly,the applying conditions and realization processes of the three stiffness ratios are analyzed,using a framesupported shear wall structure example,and some situations that should be paid attention to in using SATWE are discussed.
