高层箱形转换结构上、下楼板和转换梁共同工作分析

Analysis of interaction between top/bottom slabs and transfer beams of high-rise structure with box transfer story

采用组合有限元分析高层建筑箱形转换结构中转换梁与上、下楼板的共同工作,指出下盖板的设置能有效地分担转换梁的弯矩和轴力,而分担剪力的能力有限,同时,对转换梁抗扭并不存在一致有利的影响。并给出箱形转换层结构设计的有关建议。

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.
