通过对国内外相关研究成果的整理和分析,依据混凝土火灾爆裂危险性的影响因素,建立了混凝土结构火灾爆裂危险性分级评价体系。根据爆裂危险度值的大小将混凝土结构的爆裂危险性分为5级。爆裂危险性预测与实测结果的一致性显示了所提混凝土火灾爆裂危险性分级评价体系的有效性,可为混凝土构件和结构减灾防火设计提供参考。
Through the collation and analysis of relevant research results at home and abroad, according to the risk factors of fire explosion in concrete, a risk assessment system of fire explosion in concrete structures is established. The burst risk of concrete structures is divided into five levels according to the magnitude of the burst risk value. The consistency between the prediction of burst risk and the measured result shows that the proposed classification system of risk assessment of concrete fire burst can provide a reference for the design of fire prevention design of concrete structures and structures.
