Abstract
For keeping strengthening role of Carbon Fiber Sheet(CFS) bonded with an inorganic adhesive to insure fire safe of structure, thick-typed fireproof coating is needed for protecting CFS. Considering deformation limit of strengthened slabs in fire, temperature on bottom surface of slabs is limited to 415°C by trial calculation of deformation by ABAQUS. By analysis of temperature field of strengthened slabs by ABAQUS, fireproof coating thickness, heat conductivity coefficient and fire duration are the main factors affecting temperature on bottom surface of strengthened slabs, so key factors affecting fireproof coating thickness are heat conductivity coefficient and fire duration. Based on that, in terms of fire endurance and thermal conductivity coefficient of coating, and considering actual construction demand, advised values of fireproof coating thickness are proposed in terms of different type of coating.
