This paper deals with the fluxural behaviors of R.C beams
strengthened by steel plates. The behaviors of strengthened
beams which were preloaded up to 50%, 60% and 70% of the
ultimate load are compared with that of a beam which was not.
The structural behaviors of strengthened beams are compared
with codes in terms of deflection, rotation angle, neutral axis,
flexural stiffness, strain of steel plate, ultimate load and
falilure load.
According to the results, it is shown that strengthening of
significantly damaged beams is structurally efficient and that
the performance of stiffness and strength of the strengthened
beams are improved comparing with the originally unstrengthened
beams. The integrity, composite action, and restraining effect
of steel plates are preserved after strengthening in signficantly
damaged beams regardiess of preloading.
According to the results of comparison of behaviors with codes,
it is shown that the behavior of strengthened beams follow
simple laws of mechanics and can be predicted by codes.
