DISCUSSION ON DESIGN AND CONSTRUCTION OF RETROFITTING FRAME BEAMS AFTER FIRE BY CFRP
-
摘要: 碳纤维材料加固混凝土结构是一种新型加固技术。某110kV变电所户内电容器爆炸引起火灾,导致电容器室框架梁受到一定程度的损伤,危及结构安全,影响设备的安全运行,经分析比较多种加固方案,最终采用粘贴碳纤维布对该框架梁进行加固。Abstract: Concrete structure strengthened with carbon fiber reinforced plastic is a new retrofit method in the field of civil engineering.A 110kV transformer substation capacitor exploded,which resulted in damages to frame beams by fire.The safety of the structure was endangered.By analyzing many schemes, as a result carbon fiber reinforced plastic was used to strengthen the frame beams.
