(1 中國建筑科學(xué)研究院工程抗震研究所，北京 100013； 2 廈門市建筑設(shè)計院，廈門 361004)［摘要］采用組合有限元分析高層建筑箱形轉(zhuǎn)換結(jié)構(gòu)中轉(zhuǎn)換梁與上、下樓板的共同工作，指出下蓋板的設(shè)置能有效地分擔(dān)轉(zhuǎn)換梁的彎矩和軸力，而分擔(dān)剪力的能力有限，同時，對轉(zhuǎn)換梁抗扭并不存在一致有利的影響。并給出箱形轉(zhuǎn)換層結(jié)構(gòu)設(shè)計的有關(guān)建議。［關(guān)鍵詞］高層建筑；轉(zhuǎn)換結(jié)構(gòu)；箱形轉(zhuǎn)換層；梁式轉(zhuǎn)換層；樓板；共同工作Analysis of interaction between top-bottom slabs and transfer beams of high-|rise structure with box transfer storyRong Weisheng1, Wang Yayong1, Xie Yiren2, Xiao Wei2(1 Institute of Earthquake Engineering, China Academy of Building Research, Beijing 100013, China; 2 Xiamen Architecture Design Institute, Xiamen 361004, China)Abstract:Interaction between transfer beams and top/bottom slabs of tall building structure with box transfer story is analyzed with the composite finite element method.It is brought forward that bottom slabs of the transfer boxes could share effectively moments and axial forces, but limitedly shears of transfer beams, meantime couldn’t always benefit anti-twist of transfer beams. Concerned suggestions about structure design of box transfer story are presented.Keywords:high-rise structure; transfer story; box transfer story; beam transfer story; slab; interaction作者簡介：榮維生，高工，Email：rongweisheng@sina.com。參考文獻［1］JGJ3—2002，J186—2002高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］.［2］GB50011—2001建筑抗震設(shè)計規(guī)范［S］.
