| Abstract | ||
| This paper presents an analytical model to study flexural behavior of reinforced concrete beams strengthened with prestressed carbon fiber reinforced polymer (CFRP) plate by using finite element software (ANSYS 11.0). Eight node brick element (SOLID65 as called in ANSYS) used to model reinforced concrete, four node shell element (SHELL41) used to model prestressed CFRP plate, and two node interface element (CONTAC52) used to model epoxy (bond between reinforced concrete and prestressed CFRP plate). Experimental data of two beams strengthened with prestressed CFRP plate were tested by (Xue et.al., 2010) are analyzed to check validating of FE model. An FE Parametric study was performed based on the above model is used to study the effect of prestressed CFRP plate locations, width , and thickness. Then find that used of prestressed CFRP plate on edges increased load carrying capacity of RC beam strengthened with prestressed CFRP plate about 11% than used in center of RC beam. | ||
