高性能混凝土结构抗火研究最新进展

REVIEW OF STUDIES ON THE FIRE-RESISTANCE BEHAVIOR OF HPC STRUCTURES

对高性能混凝土抗火性能研究的最新成果进行了综述与分析 ,包括高温 (火灾 )对高性能混凝土强度和变形的影响以及高性能混凝土与普通混凝土在抗火性能上的差别等。重点对高性能混凝土在高温 (火灾 )下的爆裂现象和爆裂机理进行了评述 ,提出了改进高性能混凝土结构抗火性能的建议。

This paper engages in the analysis of the recent researches in the fire\|resistance behavior of HPC,which includes the effect of fire on the strength and deformation of HPC and the fire\|resistance difference between the HPC and NSC.The explosive spalling of HPC in fire and its mechanism is mainly concerned.In the end, some suggestions on the improvements of the fire\|resistance behavior is proposed.
