［提要］高層建筑結(jié)構(gòu)轉(zhuǎn)換層的質(zhì)量和剛度較大。隨著轉(zhuǎn)換梁質(zhì)量和剛度的增加，轉(zhuǎn)換層上下結(jié)構(gòu)的層間位移角差距明顯增大，僅限制轉(zhuǎn)換層上下結(jié)構(gòu)側(cè)向剛度比無(wú)法有效控制結(jié)構(gòu)地震作用效應(yīng)。定義層間位移角比為轉(zhuǎn)換層下部與上部結(jié)構(gòu)層間位移角的最大比值。計(jì)算分析發(fā)現(xiàn)，采用層間位移角比對(duì)結(jié)構(gòu)進(jìn)行控制可以得到比較好的抗震性能。
［關(guān)鍵詞］高層建筑；轉(zhuǎn)換結(jié)構(gòu)；層間位移角比；側(cè)向剛度
Application of Ratio of Story Drift Angles Above and Below the Transfer Floor in Seismic Design of Tall Building Structure/Rong Weisheng,Wang Yayong(Institute of Earthquake Engineering,China Academy of Building Research,Beijing 100013,China)Abstract:The mass and stiffness of transfer layer are large in highrise building.With the increasing of the mass and stiffness of transfer beam,the interstory displacement angle ratio of above and below the transfer layer diverse largely.The earthquake response of structure can not be controlled effectively only by limiting the lateral stiffness below and above the transfer story.The ratio of interstory displacement angle of above and below is defined as the maximum value of them.The calculation result shows that better structure seismic response can be got using the interstory displacement angle ratio as control index.
Keywords:highrise building； transfer structure; interstory displacement angle ratio; lateral stiffness
