Abstract EN
Using FRP bars in the concrete structures under harsh environment produces extension of those service life and dropping of the cost of their lifecycle.
This study investigated the influence of slab thickness, material of rebar, arrangement of reinforcement and mass's dropped on the dynamic behavior of RC slby using laboratory experiments.
Seven specimens 1550×1550 mm dimension with two thickness 120 and 150mm, single control specimen reinforced with steel bars and six specimens reinforced by CFRP bars were experimentally investigated under sequential dropping-weight ranged from 50 to 150kg, it was a rigid steel projectile, used to apply impacting load.
2.5m was the height of dropping.
For estimated penetration depth, three empirical formulas have been used, ACE formulae was preferable predictor than other formulas.
Different codes were used to calculation punching shear capacity and critical velocity of perforation and compared the experimental results with these codes.
The experimental results showed that the shear properties of slhave a significant effect in their general behavior.
And preferable performance in FRP slthan slreinforced with steel can be achieved which considering high strength and corrosion resistance of this material, which makes it a suitable choice for reinforcing materials.
