带地下室高层结构嵌固端相关问题研究

该文针对我国现行规范对带地下室高层结构嵌固端的相关规定,运用了计算模型和算例分析的方法,通过对地震作用下的动力特性、变形特性和内力特性等方面的比较,分别探讨了剪切型和弯曲型高层建筑结构地下室顶板作为上部结构嵌固端的判定条件。

Reseach on The Position of Fixity of Tall Building Structures with Basements

Necessary requirements to definition of the fixity of tall Building in the Code for seismic design of buildings and Technical specification for concrete structures of tall building, it takes the way of analysing dynamic calculating models and typical structure example to compare in several aspects such as dynamic character, deformation character and stress character,as to obtain the conditions for taking the top-floor of basement as the fixed of the tall building.
