碳纤维加固钢筋混凝土板耐火性能试验研究
Experimental Study on Reinforced Concrete Slabs Strengthened with CFRP in Fire
摘要
Abstract
Through standard fire tests on 5 reinforced concrete slabs,which are non-strengthened,strengthened with carbon fibre reinforced polymer (CFRP) by using organic or inorganic adhesives,protected with the fireproofing coating or not,respectively,the influences of adhesive type and the fireproofing coating on the failure modes,the displacement at the mid-span,the fire resistance limit,and so on,have been investigated.The experimental results show that the reinforced concrete slabs strengthened by inorganic adhesive-based FRP composites without fireproofing coating have good fire-resistant performance; the reinforced concrete slabs strengthened by organic adhesive-based FRP composites without fireproofing coating have bad fire-resistant performance; and the temperature of the CFRP composites in the strengthened system can be reduced effectively by using proper fireproofing measures,so that the bond strength between FRP and concrete can be guaranteed.关键词
