High rise steel structures generally refer to structural systems with six or more floors (or more than 30 meters), mainly composed of steel sections, steel plates connected or welded into components, and then connected and welded together.
High rise steel structures commonly use steel frame structures and steel frame concrete core tube structures. The latter is widely used in modern high-rise and super high-rise steel structures, and in fact, it belongs to steel-concrete hybrid structures.
High rise frame structures have a light self weight, which can reduce seismic effects, decrease transportation volume, facilitate foundation treatment, occupy less area, and increase usable area.
High degree of industrialization, short construction period, early production, early benefits, and early recycling. Comprehensive economic indicators show that steel structures are suitable for high-rise and super high-rise buildings
