Traditional methods used for strengthening of reinforced concrete (RC) structures, such as bonding of steel plates, suffer
from inherent disadvantages. In recent years, strengthening of RC structures using carbon fiber reinforced polymer
(CFRP) plates has attracted considerable attentions around the world. Most existing research on CFRP plate bonding for
flexural strengthening of RC beams has been carried out for the strength enhancement. However, little research is
focused on effect of residual deformations on the strengthening. The residual deformations have an important effect on
the strengthening by CFRP plates. There exists a very significant challenge how the residual deformations are reduced.
Shape memory alloy (SMA) has showed outstanding functional properties as an actuator. It is a possibility that SMA
can be used to reduce the residual deformation and make cracks of concrete close by imposing the recovery forces on
the concrete in the tensile zone. It is only an emergency damage repair since the SMA wires need to be heated
continuously. So, an innovative method of a RC beam strengthened by CFRP plates in combination with SMA wires
was first investigated experimentally in this paper. In addition, the nonlinear finite element software of ABAQUS was
employed to further simulate the behavior of RC beams strengthened through the new strengthening method. It can be
found that this is an excellent and effective strengthening method.
