Analysis on Fire-Resistance Performance of Slabs Strengthened by Carbon Fiber Sheet Bonded with Inorganic Adhesive

Abstract:

Fire-resistance performance of slabs can be improved if the slab strengthened by carbon fiber sheet bonded with inorganic adhesive instead of organic epoxy adhesive with low softening temperature. However, Fire-resistance performance of the strengthened slabs is not understood fully. Considering this issue, finite element analysis is done. Stating from building valid model of finite element, computing results are compared with experimental results, and rationality of the model is verified. Then plenty of parameter analysis is done. Effect of some parameters, such as range of carrying capacity increase by sheet, reinforcement ratio, load ratio to carrying capacity and thickness of slab, on fire-resistance performance of the strengthened slab is analysis. The results demonstrate that thickness of slab is the main factors influencing fire-resistance performance of the slab strengthened by carbon fiber sheet bonded with inorganic adhesive. While, range of carrying capacity increase by sheet, width of section and load ratio to carrying capacity have little influence on it. Slabs, strengthened by carbon fiber sheet bonded with inorganic adhesive, and protected by Thick-typed Fireproof Coating, perform good fire behavior.
