1991年10月22～23日,公安部消防局在四川省都江堰市主持鉴定了“钢筋砼建筑火灾烧损程度鉴定技术的研究”。该项研究完成了该课题的十一项研究内容,即确定火场的火灾温度及燃烧时间;确定砼、钢筋火灾温度作用后的残存系数;火灾温度作用后钢筋砼梁、板、柱构件横截面的温度场计算; From October 22 to 23, 1991, the Fire Bureau of the Ministry of Public Security presided over the “Research on the Identification Technology of Fire Damage of Reinforced Concrete Buildings” in Dujiangyan City, Sichuan Province. The study completed 11 studies on the topic, namely determining the fire temperature and time of fire in the fire site; determining the residual coefficient after the temperature of the concrete and rebar fire; and the cross section of the reinforced concrete beam, plate and column member after the fire temperature. Temperature field calculations;
