| Abstract: | Strengthening technology of pre - stress carbon fiber board has advantages of high strength, light weight and anti - corrosin, as well as, it can overcome shortcoming of strain lag when pasting carbon fiber board outside. By using ANSYS finite element analysis, pre -splitting concrete beam can be analyzed, and comparing numerical analysis and experimental result can be obtained. The result shows that ANSYS can simulate the whole process for pre -stress carbon fiber board to strengthen concrete beam. This method is feasible and reliable. |
