This video demonstrates a four-point bending test on an under-reinforced concrete beam.

Learning Outcomes:

Viewers will gain an improved understanding of:

• Elastic behaviour in reinforced concrete.

The beam demonstrates elastic behaviour, returning to its un-deflected position as the load is removed. The video demonstrates how a reinforced concrete beam can behave elastically provided the tension stress in the reinforcement does not exceed the yield stress of the steel.
