【提要】结构的抗震变形验算是基于性能的结构抗震设计的一项重要内容，当前各国抗震设计规范
多采用层间位移角作为结构变形的控制指标。对层间位移角限值的确定进行了简要论述，并对其中设计水准与变形验算的关系、非弹性反应分析的不完善性和不规则结构的变形验算标准等问题进行了一定的讨论。

Understanding of Storeydriftangle During Seismic Displacement Checking/Wang Yaowei,Huang Zongming(Faculty of Civil Engineering,Chongqing University,Chongqing 400045,China)
Abstract:The seismic displacement checking of the structures is one of the important terms
 of the performancebased design.The storeydriftangle is used to control the displacement during the earthquake in many country's codes.The establishment of the allowed storeydriftangles is reviewed simply,and some problems are discussed.
Keywords:storeydriftangle;seismic;performancebased design
