火灾损伤混凝土结构红外热像检测与评估

根据红外检测原理，采用红外热像技术对混凝土结构火灾损伤进行实验研究，给出了火灾损伤混凝土红外热像平均温或随时间的变化曲线，建立了混凝土红外热像平均温升与其受火温度及强度损失的回归方程，并运用上述检测模型对火灾损伤的混凝土建筑物进行了检测和评估。

Testing and Evaluating on the Damage of Fire Concrete Construction by Infrared Thermal Image

According to the testing principle of infrared radiation, infrared thermal image technique was applied to study the damage of fire concrete. The changes curves of average temperature rising of infrared thermal images of fire concrete with time was obtained. The regressive equations about average temperature rising of infrared thermal images with the fire temperature and the strength loss of concrete were established. The damage of fire concrete in construction was evaluated using above testing pattern.
