摘要
建筑物遭受火灾高温后,构件的承载力、变形、耐久性、抗震性能等受到不同程度的损伤,使整个建筑结构的耐久性、安全性降低。因此,火灾后必须对结构构件进行正确计算,然后选择合适的加固方案,使结构的安全性恢复到灾前水平。
The durability and safety of the building suffered from fire will decline as the high temperature of fire poses damages to the bearing capacity, durability and seismic performance of the structural members to some extent. Therefore, it is necessary to do correct calculation of the structural members after fire, which will help to choose the right reinforcing scheme and resume the structural safety.
