摘要(Abstract):

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。
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.
