    摘要: 在实际工程设计中,多数结构工程设计人员并未重视高层建筑结构嵌固端的选择。这样往往会造成材料浪费,也会给高层建筑结构留下隐患。对于高层建筑结构嵌固端的定义,部分结构设计人员也存在误区,认为是力学嵌固,其实应为强度嵌固。规范对地下一层顶板作为嵌固端明确了要求。本文对三种地下室平面面积型式不同的高层建筑结构嵌固端做了初步的探讨,得出了一般情况下,不同地下室平面型式嵌固端的位置,并得出了地上一层与相关范围地下一层侧向刚度比是衡量地下一层顶板能否作为高层建筑结构嵌固端的关键。In the practical engineering design, structural engineering staffs did not attach importance to fixed end of high-rise building structure. This will cause material waste, and will also leave hidden troubles to the high-rise building structure. Some of the structural designers have mistakes in the definition of fixed end of the tall building, who regard them as mechanics embedment, but in fact it should be strength-mounted. Specification makes requirements clearly about the roof of the underground layer as embedding end. In this paper, three basement flat area types of high-rise building structure embedded end have been studied. It comes to conclusions 1) there are different embedding positions in different basement flat forms under normal circumstances, and 2) the lateral stiffness ratio of ground floor with the relevant range of underground floor is the key to measure whether the basement roof can be used as a high-rise building structure embedded fixed end.
