| 摘 要： | 实验结果表明:四面或两面对称受火的火伤混凝土构件，其截面上的温度分布可看作
混凝土构件表面沮度(T，)及中心沮度(工)的函数。本文提出了用超声波法评定其表
面温度及中心温度的方法.按该方法计算的结果与若干实例中实测结果吻合良好.

| Abstract: | Based on experiments, this paper puts forward that for fire-damaged concrete element heated symmetrically on two or four sides, the temperature distribution on its cross section may be considered as some function of two variables T_f (temperature on surface)and T_c (Temperature at center of section) T_f and T_c can be determined by the ultrasonic pulse method with proposed Formulas and methods. The results agree well with those, measure by some experimental research. |
