摘要
利用计算机软件对火灾下粘贴CFRP钢筋混凝土构件温度分布的影响因素进行参数研究,结果表明,迎火面辐射率以及对流换热系数的波动对CFRP的温度影响很小,增加保护层厚度可以有效降低CFRP的温度。
In this paper, parametric studied are conducted to find the main factors that affect the temperature distributions of insulated CFRP strengthened concrete beams subjected to fires. Results show that the CFRP temperature is un-sensitive to the changes of resultant emissivity and convection coefficient at the fire-exposed surfaces, and increasing the thick of fire protection can drop the CFRP temperature obviously.
