Performing torsion testing on steel reinforcement - But Why?

[MatthewMansfield]

Hi all

Its been a while since I posted - its good to be back.

I wanted to ask a question related to torsion specifically why it is important to perform torsion testing on steel reinforcement?

The only reasons why its important in my mind is because:-

1) You can calculate the sheer stresses a steel reinforcement will experience and thus can design steel reinforcement such that what withstand such forces?


Can I ask the community what they think? why is it important to perform torsion testing on steel reinforcement.

Thank you all.

Are you suggesting torsion testing of individual bars? Or, torsion testing of reinforced concrete members? Never heard of torsion testing of bars. Tension testing of reinforcing bars is common.

I've done thousands of materials tests, including steel, aluminum and other metals including rebar....never seen or heard of a torsion test for rebar. Not even sure there's a machine for such. Could be related to shear modulus, but not something we normally consider in design.

Torsion testing of a reinforced concrete beam section makes sense, but not the rebar alone.
