Jacketing:
Jacketing is a strengthening technique used to enhance the load-carrying capacity of structural members like beams or columns.
It involves adding a new layer of concrete, along with reinforcement, around the existing member.
Why Jacketing is Effective:
It increases the cross-sectional area of the member.
It improves its strength, stiffness, and durability.
It provides additional confinement and improves resistance to axial and lateral loads.
