高层建筑中特别是高层住宅建筑常采用剪刀墙结构体系,研究表明仅需较少的剪刀墙就能满足工程要求。为了降低层高和灵活布置隔墙,需要采用大跨度的楼板,量大面广的住宅建筑为建成大开间灵活隔断的形式,也需要采用大跨度楼板。经过多种方案综合比较,认为冷轧 High-rise buildings, especially high-rise residential buildings, often use the scissors-wall structure system. Studies have shown that fewer scissors walls are required to meet engineering requirements. In order to reduce the height of the floor and to flexibly arrange the partitions, large-span slabs are required. Large-scale residential buildings are constructed in the form of flexible partitions for large bays, and large-span floors are also required. After comprehensive comparison of various options, it is considered that cold rolling
