Tubular Columns

Steel-reinforced concrete-filled stainless steel tubular (SRCFSST) columns combine the advantages of concrete-filled stainless steel tubular (CFSST) columns and steel-reinforced concrete (SRC) columns, resulting in excellent corrosion resistance, good economy, good ductility, and excellent fire resistance. Thus, SRCFSST columns have many potential structural engineering applications, especially in offshore structures. The performance of SRCFSST columns at elevated temperatures is investigated by finite element (FE) analysis in this paper. Firstly, FE models capable of capturing the full load-deformation response of structural members at elevated temperatures are developed and validated against relevant published tests on CFSST and SRC columns under fire conditions. Based on the validated FE models, the behavioral mechanisms of the SRCFSST columns under fire are explained by analysis of the sectional temperature distribution, typical failure modes, axial deformation versus time response, and load redistribution. Finally, the fire resistance of SRCFSST columns is evaluated in comparison to CFSST columns with equivalent sectional load-bearing capacity at ambient temperature or equivalent steel ratios. The results lay the foundation for the development of fire resistance design rules for SRCFSST columns.

Simplified Calculation Method

The fire resistance of concrete filled steel tubular column is usually obtained by the numerical analysis method, which is difficult to operate and not convenient in the actual civil engineering. So it is necessary to study the simplified calculation method. A large number of numerical simulation results of the temperature distribution of the section and the bearing capacity at high temperature of the concrete filled steel tubular columns are analyzed. The influences of secondary parameters are simplified. The simplified calculation method at 150 min and 180 min for the bearing capacity at high temperature of concrete filled steel tubular columns subjected to axial compression and fire is presented on the basis of comprehensive analysis of the numerical calculation results. The calculation results can be used as the basis to judge the fire resistance. It is shown by the comparison with the experimental results that the precision of the simplified calculation method can meet the requirements of engineering application.

The Impact

Concrete-Filled Steel Tube with high capacity, good ductility and toughness, convenient construction, good fire resistance and other advantages. Currently[1] . Concrete-Filled Steel Tube structure has been widely used in the basic components and the overall structure of behavioral research has made many achievements. There are many advantages of concrete pipe above, but it also has fatal flaws, Stainless steel steel that is the difference[2]. The stainless steel has a beautiful appearance, durability, corrosion resistance, low maintenance costs, good fire resistance and other advantages. New stainless steel pipe concrete structure has both ordinary steel concrete good mechanical properties and excellent durability of stainless steel, can be widely used in buildings and bridges of the marine environment as well as some of the high durability and aesthetic requirements important building structures. Based on the outer stainless steel hollow sandwich - the carbon steel pipe shaft of light pressure test concrete results of load and displacement of the structure, variation of load and strain, and the impact of the empty heart of these parameters.
