Novel Torsional Reinforcement of Concrete Beams Utilizing Cross-Rod Steel Reinforcement

Autor: Adnan Ibrahim Abdullah, Assim M. Lateef

Publikováno v: Tikrit Journal of Engineering Sciences, Vol 30, Iss 3 (2023)

External strengthening of reinforced-concrete beams is challenging because of the building system complexity or the beam geometry. The major challenge is choosing an appropriate strengthening method to overcome its low torsion strength. Therefore, th
