T he tem perature distribution by the A BAQU S is in good agreem ent w ith the expermi ental results of m odels, wh ich show s that the analysism ethod in this paper is reasona ble o r practicable. In addition, this paper also analyzes respective ly the temperature fields o f re in forced concrete fram e jo ints under tw o f ire cases, that is, one case is three sides surrounded by f ire and the other is four sides surrounded by fire. A nd, in the end, the paper com pares the tem perature d istribution characterist ics of the reinforced concrete fram e jo ints under the t
