［摘要］從分析結(jié)構(gòu)周期與頂點位移、層間位移角的關(guān)系出發(fā)，論證了控制結(jié)構(gòu)最大層間位移角實際上就隱含控制了相應結(jié)構(gòu)的平動周期值，確定了高層建筑的最大層間位移角限值就沒有必要再另行控制結(jié)構(gòu)的平動周期。論述了結(jié)構(gòu)抗扭設(shè)計的三個核心問題，分析了單一控制扭轉(zhuǎn)周期比存在的問題。

Abstract: Based on analysis of the relationship between structure period, top displacement and story drift, it was testifies that controlling the maximum story drift actually control the translational basic period value of the structure implicitly. So it is not necessary to control the translational basic period value of the structure if the maximum story drift limit value of the high-rise building is certain. Three key problems on torsional design of the structure were also discussed and some questions in controlling simply torsional period ratio were analyzed.
Keywords: high-rise building; translational period; top displacement; story drift; torsional period; torsional period ratio
