Behavior of reinforced concrete beams with minimum torsional reinforcement

Engineering Structures, 2007
An experimental investigation was conducted on the behavior of thirteen high-(HSC) and normal-strength concrete (NSC) full-size beams with relatively low amounts of torsional reinforcement. The crack patterns, the maximum crack widths at service load level, torsional strength, torsional ductility, and post-cracking reserve strength results of the ...

Torsional stiffness of reinforced concrete members subjected to pure torsion

Magazine of Concrete Research, 1972
Synopsis A method is described for determining the torsional stiffness at the cracked stage of reinforced concrete members subjected to a pure torsional moment. The method is based upon a truss analogy for torsion. Theoretical expressions are deduced for the Torsional stiffness of beams of arbitrary and rectangular cross-sections.

Torsional strength of reinforced concrete beams

Canadian Journal of Civil Engineering, 2000
A simple method for predicting the ultimate strength and mode of failure of reinforced concrete beams subjected to pure torsion is presented. This method is an extension of a recently developed method for predicting the strength of membrane elements subjected to pure shear that was also applied to beams subjected to combined shearing forces, bending ...

BEHAVIOUR OF REINFORCED CONCRETE BEAMS IN TORSION.

Proceedings of the Institution of Civil Engineers, 1983
In the paper a simple but reasonably accurate method is developed for the analysis of reinforced concrete sections in pure torsion. Based on test behaviour and results, an expression for ultimate torsional strength of under-reinforced sections is extended to include partially and completely over-reinforced sections.

LONGITUDINAL REINFORCEMENT IN CONCRETE BEAMS IN TORSION

2005
This paper explains the behaviour of reinforced concrete beams based on various ends parameters - torque, torsional rigidity and torsional ductility factor. The input parameters adopted for the study to identify the influence were longitudinal tensile as well as compressive reinforcements and torque to bending moment ratio (T/M) as 1 to 3.

Textile Reinforced Concrete (TRC) as Torsion Strengthening

IABSE Congress, Chicago 2008: Creating and Renewing Urban Structures – Tall Buildings, Bridges and Infrastructure, 2008
<p>More and more old buildings must be strengthened. There are various methods by which to improve the torsional resistance of existing reinforced concrete elements. One method entails the use of Textile Reinforced Concrete (TRC). Test results will be used to demonstrate that TRC combined with AR-glass can be used to strengthen the torsional ...

Torsion Tests on Reinforced Concrete Slab Elements

Journal of Structural Engineering, 1987
Results of torsion tests to failure on nine orthogonally reinforced concrete slab elements are described and compared with various theoretical predictions. The specimens had dimensions of 200 mm × 1700 mm × 1700 mm (8 in. × 67 in. × 67 in.). Geometrical reinforcement ratios ranged from 0.25 – 1.0%. Post-cracking behavior of the specimens was accurately

FIBRE REINFORCED CONCRETE IN PURE TORSION AND IN COMBINED BENDING AND TORSION.

Proceedings of the Institution of Civil Engineers, 1979
The paper studies the influence of steel fibres on the torsional and flexural rigidity of concrete beams. Ultimate load tests were carried out on square beams subjected to pure torsion and on rectangular beams subjected to combined bending and torsion.

Torsional stiffness of reinforced concrete rectangular members

Magazine of Concrete Research, 1979
Synopsis The paper deals with the determination of the torsional stiffness of rectangular reinforced concrete members under pure torsion and torsion combined with bending and shear. The energy principle is applied to a four-plate shear wall model representing the member to obtain the stiffness under pure torsion.

Response of Reinforced Concrete Slab Elements to Torsion

Journal of Structural Engineering, 1987
Methods of predicting the load‐deformation response of orthogonally reinforced concrete slab elements subjected to pure torsional moments in the reinforcement directions are presented. Uncracked, cracked, and ultimate behavior are discussed, treating the reinforcement as linearly elastic‐perfectly plastic and using linear, nonlinear (parabolic), and ...
