Torsional behaviour of reinforced concrete beams with ...

Jun 01, 2016 · A reinforced concrete (RC) structural element such as peripheral beams, ring beams at bottom of circular slab, beams supporting canopy and other types of beams are subjected to torsional loading. Strengthening or upgrading becomes necessary for these beams when they are unable to provide the resistance.

Study of torsional behavior of reinforced concrete beams ...

Nov 21, 2018 · This paper investigates the strengthening of reinforced concrete (RC) beams for its torsional behavior using aramid fiber strips. Most of the time aramid fiber is used as an externally bonded reinforcement to increase flexural and shear strength of RC beams. An attempt is made to use it for improving torsional moment carrying capacity of RC beam. Torsional failure mostly occurs in earthquake ...

Torsional behavior of reinforced concrete beams with corroded ...

An experimental study was conducted to investigate the pure torsional moment capacities of corroded reinforced concrete beams. An accelerated corrosion pool was used to corrode the reinforcement bars embedded in reinforced concrete beams. Seven reinforced concrete beams at corrosion levels between 0% and 17% were examined under pure torsion tests.

Behaviour of concrete beams under torsion: NSC plain and ...

Oct 19, 2007 · A simple computation procedure is developed to predict the general behaviour of reinforced concrete beams under torsion. Both plain and hollow normal strength concrete beams are considered. Different theoretical models are used to reflect the actual behaviour of the beams in the various phases of loading. To pass from a phase to the following one, transition criteria need to be taken into ...

5 CHAPTER 5: TORSION

inelastic behavior of concrete, and the intricate state of stress created by the interaction of shear, moment, and torsion make an exact analysis unfeasible. The current torsion design approach assumes no interaction between flexure, shear and torsion. Reinforcement for each of these forces is designed separately and then combined.
