In this paper, a comparative investigation into the behavior of concrete-filled steel tube column and reinforced concrete column with the same quantity of material and cross-section sizes under axial load have been undertaken using the finite element method. Both is analyzed to compare the axial compression performance,including bearing capacity, ductility and their mechanism. The results of the analyses clearly exhibit that bearing capacity of concrete-filled steel tube column is higher about 25% than that of reinforced concrete column. Under the same conditions, ductility of concrete-filled steel tube column is better than reinforced concrete column, its application is recommended in construction practice.

Concrete Filled Steel Tube

A three-dimensional finite element analysis model was developed using ABAQUS to simulate the temperature distributions of circular concrete filled steel tube reinforced concrete column in this paper. The influence of main parameters on the temperature distribution, such as heating time, section diameter, and steel tube diameter, was analyzed. This provides valuable information about structural fire resistance and structural behaviour of concrete filled steel tube reinforced concrete column structure under fire.

In the case of small increase of cross-section, concrete column strengthened by circular steel tube can increase the bearing capacity greatly as well as ductility. This has resulted in engineering welcome. This paper studied the common work performance of reinforced concrete column strengthened by circular steel tube in three different conditions test of axial compression. The results show that outsourcing steel and core column can be achieved interaction. By strengthening, it can improve the load capacity of the concrete column as well as ductility. With the increase in initial load, although it has little effect on the bearing capacity of reinforced columns, it can affect the ductility to some extent. This paper can provide experimental basis for engineering applications.

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.

Based on experimental research on plain concrete columns with high strength concrete core, the formula to predict the bearing capacity of concrete columns with high strength concrete core under axial compression loading was brought forward in previous paper, in order to verify the formula whether right, axial compression test including 3 concrete columns with high strength concrete core and 1 ordinary reinforced concrete column were completed, and the failure characteristic was analyzed additionally. According to experimental results, it can be shown that the failure modes of concrete columns with high strength concrete core are similar to that of ordinary reinforced concrete columns, however, the bearing capacity of concrete columns with high strength concrete core is significant higher compared with that of ordinary reinforced concrete column; the results of the bearing capacity obtained by the formula (2) was in good agreement with the experimental results.
