Abstract:
The main objectives of this paper are threefold: firstly, to report a series of fire tests on concrete-filled steel SHS (square hollow section) and RHS (rectangular hollow section) columns with square and rectangular sections. Secondly, to analyze the influence of several parameters, such as fire duration time, sectional dimension, slenderness ratio, load eccentricity ratio, strength of steel and concrete on the residual strength index (RSI) of the composite columns. Finally, to develop formulas for the calculation of the fire resistance and the fire protection. thickness of the concrete-filled steel SHS and RHS columns, such formulas are suitable for incorporation into building codes. The concept of this paper were used to provide data on the necessary fire protection measures for the concrete-filled steel SHS columns used in a high-rise building, Ruifeng, Shangye Building in China.
