This paper presents analytical model to
study flexural behavior of reinforced concrete beam 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 beam strengthened with prestressed CFRP plate 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.
