Abstract
This paper studies the behavior of simply
supported steel I-beams strengthened with carbon fiber
reinforced polymers (CFRP) strips on the web as shear
reinforcement. The experimental program contains seven
simply supported steel beams. One of them was
considered as a control beam and the other specimens
were strengthened with different schemes; varying the
position of CFRP strips to the web, its number of layers
and its angle of orientation. The results show that
applying CFRP strips on the web of the steel I-beams was
an effective strengthening method for increasing the load
bearing capacity and decreasing the deformations. Using
two layers of diagonal CFRP strips on both sides of the
web realized the highest increasing in the load capacity.
Moreover, finite element analysis method has been
utilized to analyze the tested specimens using ANSYS. A
great convergence between the experimental results and
the corresponding ones obtained from finite element
simulation.
