Abstract EN
This study presents an experimental investigation on the behavior of fourteen reinforced self-compacting concrete tapered beams with or without strengthening.
The strengthening was applied by using carbon fiber reinforced polymer (CFRP) to beams with simply supported span and subjected to two points loading.
Those beams have an overall length of 2000 mm, a width of 150 mm and a height of 250 mm at supports (hs) and a mid-span depth (hm) varies between 150 mm and 200 mm and with different strengthening scheme, they are investigated to evaluate the behavior at experimental test and to study the effect of the parameters which include haunch angle α, shear-span to effective depth ratio a/d and strengthening strips number and locations on beams behavior.
The experimental results show that decreasing the value of haunch angle α increased the load capacity by about 56% and decreased the corresponding deflection while when tapered beams are strengthened by CFRP the ultimate load is increased up to 39% with decrease of deflection.
On the other hand, increasing a/d ratio leads to a decrement in load capacity and increment in deflection.
