Construction Technology of Lift Slab with Concrete Filled Steel Tube Columns

Abstract:

Abstract. This paper discusses a lift slab building with concrete filled steel tube columns. Lift slab construction as a methodology has advanced on improvements in traditional lift slab construction technology. When concrete filled steel tube columns are used, the strength of the concrete in the tube is obviously enhanced by the hoop action derived from the steel tube. The section of the concrete filled steel tube column is smaller than the section of the reinforced concrete column, thus realizing cost savings in material and labor. Also, because the steel tube hasn’t been filled with concrete when it is assembled, the steel tube is much lighter than the traditional reinforced concrete column. Thus, the assembly of steel tube columns without concrete is easier and crane-lifting requirements are less. This paper describes the construction of a building utilizing current LSCSTC – Lift Slab Construction with Concrete filled Steel Tube Column technology.
