Reliability of reinforced concrete beams in torsion

2021
The level of safety associated with the ACI Standard 318-83 design criteria for torsional reinforced concrete members is evaluated. Advanced first-order, second-moment reliability analysis is used to compute the reliability index. Reinforced concrete beams, subjected to both equilibrium and compatibility torsion, are analyzed.

Torsional behaviour of reinforced fibre concrete beams

International Journal of Cement Composites and Lightweight Concrete, 1985
Abstract Pure torsion tests were conducted on rectangular fibre concrete beams reinforced in three different ways: without bar reinforcement, with longitudinal bars only and with longitudinal bars and transverse hoops. Fifteen tests investigated the influence of the volume fraction of discrete steel fibres and the amount of longitudinal and ...

Effective Torsional Rigidity of Reinforced Concrete Members

ACI Structural Journal, 2004
A simple procedure for calculating effective torsional rigidity of reinforced concrete (RC) members is presented. The proposed method relates torsional rigidity, an important parameter for 3-D analysis of RC structures, to the applied torque taking the effect of reinforcement into account.

Cyclic Torsion Tests on Reinforced Concrete Beams

Journal of Structural Engineering, 1987
Reversed cyclic torsion tests on nine normal‐weight and three lightweight reinforced reinforced concrete beams are reported, along with nonreversible cyclic torsion tests on four reinforced concrete beams and two companion static tests. The variables studied were the peak torque, the range and the frequency of loading.

The influence of CFRP on Reinforced Concrete Beams Subjected to Torsion [PDF]

The primary objectives of this research thesis is to investigate the behaviour of reinforced concrete beams subjected to torsion, and more importantly the influences of FRP wrapping on these beams. The effects of wrapping these beams in different configurations also compiles to another objective of this thesis.A controlled experimental procedure was ...

TORSION AND BENDING IN REINFORCED AND PRESTRESSED CONCRETE MEMBERS.

Proceedings of the Institution of Civil Engineers, 1971
WITH RESPECT TO ULTIMATE STRENGTH, PRESTRESSED MEMBERS CAN BE TREATED AS NONPRESTRESSED MEMBERS WITH AN EQUIVALENT AMOUNT OF NORMAL REINFORCEMENT. THE THEORY FOR REINFORCED BEAMS CAN THEREFORE BE EXTENDED TO REINFORCED AND PRESTRESSED BEAMS. THE EXPERIMENTAL BEHAVIOR OF REINFORCED CONCRETE BEAMS UNDER TORSION CONFIRMED THE VALIDITY OF A SPACE TRUSS ...

Failure Mechanisms for Reinforced Concrete Beams in Torsion and Bending

1976
To describe the failure of reinforced concrete beams with thin-walled closed cross section in torsion and bending, Lampert [2, 3] used a space truss model based on the lower bound theorem of the Theory of Plasticity. The good correspondence between theory and test results stimulates to generalize the model.

Torsion and bending in longitudinally reinforced concrete beams

Building Science, 1973
Abstract This paper shows that theoretically the failure moments of a concrete member reinforced with longitudinal steel only and subject to torsion and bending, are related by three theoretical general interaction equations derived by considering two modes of behaviour.
