Play an AI-generated podcast conversation about this lesson

In the context of torsion design, how is a beam idealized according to the text?

As a solid beam with stirrups and longitudinal bars providing resistance.

As a hollow tube with stirrups and longitudinal bars ignored.

As a thin-walled tube with the core concrete cross section neglected. (correct)

As a solid beam with core concrete cross section considered.

After cracking in torsion, what primarily provides the torsional resistance in a reinforced concrete beam?

Closed stirrups and longitudinal bars near the surface. (correct)

Core concrete cross section.

Closed stirrups located at the core.

Longitudinal bars located near the core.

What part of the cross section is assumed to provide resistance in the thin-walled tube analogy for torsion design?

Core concrete cross section.

Hollow sections of the tube.

Longitudinal bars at the center of the beam.

Outer skin of the cross section roughly centered on closed stirrups. (correct)
