【提要】結(jié)構(gòu)的抗震變形驗算是基于性能的結(jié)構(gòu)抗震設(shè)計的一項重要內(nèi)容，當(dāng)前各國抗震設(shè)計規(guī)范
多采用層間位移角作為結(jié)構(gòu)變形的控制指標(biāo)。對層間位移角限值的確定進行了簡要論述，并對其中設(shè)計水準(zhǔn)與變形驗算的關(guān)系、非彈性反應(yīng)分析的不完善性和不規(guī)則結(jié)構(gòu)的變形驗算標(biāo)準(zhǔn)等問題進行了一定的討論。

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
