某钢筋混凝土冷冻库火灾后结构性能测评

The Evaluation of a Reinforced Concrete Freezer after Fire

本文通过对某钢筋混凝土冷冻库火灾事故后的现场勘查,推定建筑火灾温度分区,同时初步鉴定评定构件损伤状态等级。并对过火构件进行材料性能检测,对建筑物整体及梁柱构件进行变形测量。根据现场检测鉴定结果为后续加固处理方案提供依据。该冷冻库灾后结构性能的评测可为类似工程提供参考。

Based on the scene investigation of a reinforced concrete freezer after fire, this paper deduced the temperature partitions and e-valuated the damage level of the structural components.The structural materials testing and deformation measurement for building and beam-column members were carried out.The evaluation could provide the basis for the following reinforcement scheme, which also offers refer-ence for similar projects.
