The issue of repairand reinforcement of
structures is one of the major branches of civil
engineering. In this direction, the reinforcement
of the pressure members, especially the reinforced
concrete columns by reinforced polymer sheetsis
considered as one of the conventional methods in
reinforcing these members. By confining the
pressure member and preventing lateral expansion
resulting from the Poisson’s effect,the FRP
sheetbrings about an increase in compression
strength and ductility. In this laboratory research,
the effects of different methods of reinforcing
concrete columns by CFRP sheets including the
effect of the width of reinforcing sheets on
ductility and stress-strain behavior of the concrete
columns in the presence of internal reinforcement
of the column were studied. The steel
reinforcement of column includes evaluation of
the effect of longitudinal and transverse steel bars,
number of transverse bar, and also development
bar of longitudinal reinforcement on the rate of
confinement.
The results of this research show that by
suitable arrangement of CFRP reinforcing sheets,
the confinement in the reinforced concrete
columns can be created appropriately
