Bending failure of a prestressed concrete beam: Materials Lab on-line

This video demonstrates a four-point bending test on a pre-stressed concrete beam. Learning Outcomes. Viewers will gain an improved understanding of: - The concept of pre-stress applied to concrete beams - How pre-stress can be used to create beams of increased stiffness - Ductile behaviour The beam demonstrates ductile behaviour as it is loaded to failure. The video demonstrates how pre-stressing can be used to improve the stiffness properties of a reinforced concrete beam. It also shows how the beam
