某高层建筑中转换层的结构设计与施工

摘要

This paper introduces the design and construction process of transfer layer in high-rise building,describes conversion scheme selection,stiffness varying,shear bearing capacity rate limitation,and steel section selection and so on.Some special structural measures are adopted in high elevation transfer and connection of steel truss and concrete,which is proved feasible through construction practice.%介绍了一带钢桁架转换层框剪高层结构的设计与施工过程,针对此类结构,阐述了转换方案选择、层刚度突变、层受剪承载力比例限值、型钢截面的选择等问题的解决;针对高位转换、钢桁架与混凝土的连接采取了一些特殊的构造措施,经施工实践检验是可行的。
