Simulate Analysis On CFRP Strengthened Reinforced Concrete Structure With FEA Method Under Fire

CFRP strengthened reinforced concrete Structure drive extensive application recently. However it is sensitive to temperature for this reinforced technique, Little people present the performance of CFRP strengthened reinforced concrete Structure under fire, Most reinforced concrete need fire protection, so it is significant to research this problem.In this thesis, the FEA software ANSYS is used to simulate CFRP strengthened reinforced concrete beam, After compare FEA results and TEST results, the similar conclusion can be draw out. Following, reinforced concrete full-scale slabs which was subject to fire test were simulated by finite element method .The temperature distribution of reinforced concrete full-scale slabs was obtained well. The test results agree well with the results of finite element analysis through setting up parameters reasonable. It is proved sufficiently that the finite element method can simulate reinforced concrete full-scale slabs which were subject to fire test well. Then Finite element analysis of temperature field of CFRP Strengthened RC-column under fire was presented. Fireproof protect layer or non were considered. The reasonable thickness of protect layer can find throw comparing different thickness of protect layer which affect the temperature field of RC-column. Setting up parameters reasonable, the test results which were available in relative literature agree well with the results of finite element analysis.Finally, the coupling field of CFRP strengthened reinforced concrete column under fire is discussed; the coupling field types and method are narrated. Other problems need to be pay attention are brought forward and some advices are present.
