[摘要] 高层建筑上部结构嵌固端位置的选取是非常重要的，而工程实践中嵌固端的选取是非常复杂的问题。新颁布的 10版《建筑抗震设计规范》和《高层建筑混凝土结构技术规程》对于地下室顶板作为上部结构嵌固端的要求有所变化，本文根据这两本规范,参考有关文献,对工作中碰到的上部结构嵌固端的以下问题做了探讨:1)地下室顶板开洞口;2)地下室一侧有地下车库通道;3)地下室顶板不能作为嵌固端时的措施;4)上部结构与地下室是否整体统一计算;5)地下室顶板作嵌固端时与其他专业协调问题。本文对以上问题提出了解决思路和建议,以求达到安全、经济的设计目标,并供设计同行参考。[关键词] 规范修订;地下室顶板开洞口;地下车库通道;非嵌固端措施;整体统一计算;专业协调问题Certain discussion of basement top slab as the fixed-end based on seismic code (2010) and high-level specification (2010)Li Xianjie1, Shi Qijian1, Huang Xinglong(Liao Cheng Institute Of Architecture Design, Liaocheng 252000, China)Abstract: The selection of the fixed-end of superstructure is an important issue, and which is complicated in the practical design .With <Code for seismic design of buildings>(2010) and<Technical specification for concrete structures of tall building>(2010) revision ,the requirement of basement top slab on fixed-end has changed , the paper based on seismic code and high-level specification revision and relevant reference, made the following discussion of fixed-end of superstructure:(1)basement top slab opening;(2)underground garage channel on side of the basement; (3) basement top slab can not serve as fixed-end；(4)whether the superstructure and basement unified calculate or not;(5)coordination of profession when basement top slab serve as fixed-end of superstructure .The paper put forward solution thread and suggestion on these above cases in order to safe and economical design ,which can be referenced for design peer.Keywords: Code revision; basement top slab opening; underground garage channel; strengthening measure on non-fix-end of superstructure ; unified whole calculate ; coordination of profession
