Abstract
This paper presents an investigation of the effect of the width-to-thickness ratio of
steel plates in steel-concrete composite beams. A total of 13, 200x350x3000 mm
reinforced concrete beams were tested. The first group of beams was strengthened
with 6 mm steel plates and the second group of beams was strengthened with 8 mm
steel plates, in flexure. All beams were tested under two-point static loading system.
The results show that the addition of glued steel plates to a reinforced concrete can
substantially increase the flexural stiffness of beams, reduce cracking and structural
deformations at all load levels.
