Carbon Fiber Reinforced Concrete Structure Fire-resistant Performance Analysis

Carbon fiber reinforced concrete structure compared with other reinforcement technology, a lightweight, resistant, high strength and the advantages of convenience, consolidation in the field of large-scale application. But compared to reinforced concrete refractories, carbon fiber material very poor fire resistance properties, material properties in the fire environment, as the temperature rises rapidly declining. This fatal flaw affected greatly reinforced the safety of the structure, to a large extent hindered the carbon fiber reinforcement in practical engineering further application. On the carbon fiber reinforced concrete structures for fire resistance design is the use of the building in order to strengthen security, improve the structure of reinforced fire environment in the fire resistance of the time.In this paper, using the finite element software ANSYS at room temperature carbon fiber reinforced concrete component of the force and deformation analysis, and simulation results and experimental results are compared analysis, finite element analysis of the feasibility. Then use the basic principles of heat transfer, reinforced concrete structures in the fire in the course of the temperature field analysis. Finally comparison of carbon fiber reinforced concrete structures in the availability of fire protection and fire prevention layer thickness of the different sections of the impact of temperature, carbon fiber that can guarantee the reasonable security protection layer thickness. And the actual project for the future to provide certain reference.The findings in this paper are valuable to the human resources administration in universities and colleges. Because it is written from a completely new angle and together with the characters of the knowledge economy era. And it hopes to take the theory to a high layer.
