The present work presents a 
numerical study to simulate the 
behavior of reinforced concrete beams 
strengthened with steel plates. The 
study is carried out using two un-strengthened 
RC beams and two RC beams strengthened with 
(1mm, and 3mm) steel plates. The beams are 
modeled and analyzed by nonlinear FEM using 
ANSYS v14.5. The numerical results are in good 
agreement with experimental load-displacement 
curves and ultimate load carrying capacity.
