STRENGTHENING OF RC BEAM WITH PREFABRICATED RC PLATE
In
retrofitting of Reinforced concrete
(RC) beams which are insufficient in terms of shear and flexural capacities are
strengthened by various methods. Steel and fibre reinforced polymer (FRP) plate
bonding methods are very widely used in strengthening of beams. Strengthening
methods such as bonding steel and FRP plates have deficiencies as corrosion,
fire and buckling. In this work, it is aimed to strengthen damaged RC beams
using prefabricated RC rectangular plate. The rectangular cross-sectional
plates were bonded to the bottom side of the beams by rods and epoxy. The
experimental results were compared with the theoretical values. The
experimental results were compared with the theoretical values In addition;
post-elastic strength enhancement and displacement ductility of beams were
investigated. The advantages of this method do not require shuttering, concrete
and steel workmanships in situ. Also, the application of this method is very
easy and result in reduction in retrofitting cost compared to other methods.
