Behavior of Reinforced Concrete Plates under Pure Torsion

Published 2021. The behavior of reinforced concrete members under torsional loading has interested many researchers during the last decades. These researches focused mainly on the response of reinforced concrete beams at different reinforcement conditions and the size effects. On the other hand, the behavior of concrete plates or slabs has not ...

Torsional Behavior of Plain High-Strength Concrete Beams

Sep 01, 1990  The plain high-strength concrete beams under torsion failed suddenly and violently along a smooth surface. The skew-bending theory is found suitable for predicting the torsional capacity of plain high-strength concrete beams, provided that the splitting tensile strength is taken to represent the concrete tensile strength.

BEHAVIOUR OF CONCRETE UNDER TENSION - The Constructor

Concrete has a low failure strain in uniaxial tension. It is found to be in the range of 0.0001 to 0.0002. The stress-strain curve in tension is generally approximated as a straight line from the origin to the failure point. The modulus of elasticity in tension is taken to be the same as that in compression. As the tensile strength of concrete ...
