According to the basic principles of heat transfer, the thermal field of SRC columns under fire is analyzed by finite element analysis software ABAQUS and the calculated results agree well with experimental data at home and abroad. On this base, the influence of parameters of sectional dimensions, length-to-width ratio of the section, steel ratio and reinforcement ratio to the distributing circumstance of thermal field of SRC columns are analyzed. The results show that parameters of sectional dimensions and length-to-width ratio are the most important factors affecting the distributing circumstance of thermal field of SRC columns. The larger the parameters of sectional dimensions, the lower the component temperature. The greater the length-to-width ratio, the greater the component temperature is. Steel ratio and reinforcement ratio have almost no effect on the distributing circumstance of thermal field of SRC columns. The achievements make it possible to study further the mechanical performance of SRC columns at high temperature.
