| Abstract: | Steel reinforced concrete(SRC) and reinforced concrete(RC) columns are well known members used extensively in engineering structures.Factors influencing on the fire resistance of SRC and RC columns include the sectional dimensions,the slenderness ratio,the load ratio under fire,the steel reinforcement ratio,the section steel ratio,the load eccentricity ratio,the depth to width ratio of the section,the strength of the steel and the concrete.The influence of the changing geometrical parameters,physical parameters and load parameters mentioned above on the fire resistance of SRC and RC members is analysed in this paper,and several issues on the fire performance and fire resistance design are discussed. |
