Steel Jacketing is ideal for industrial facilities and time-sensitive strengthening projects.. This method encases existing columns with steel plates or sections to rapidly enhance load-carrying capacity, stiffness, and ductility with minimal size increase.
A column jacketing technique where steel plates or sections are added around RCC columns to increase strength, improve load capacity, and enhance structural stability. It provides strong confinement, improving axial strength and seismic performance.
The system is selected based on load requirements, site conditions, and structural design.
Steel jacketing is required when columns show cracks, corrosion, reduced load capacity, or structural weakness due to aging, overload, or seismic damage.
Steel jacketing improves load-bearing capacity, enhances ductility, provides confinement to concrete, repairs damaged columns, and increases overall structural safety.
Steel jacketing offers faster installation, higher strength, and better confinement, while concrete jacketing is more economical for large sections. The choice depends on structural needs.
Steel plates or sections confine the concrete core, reduce lateral expansion, and improve axial load capacity, resulting in stronger and more durable columns.
With proper design and corrosion protection, steel jacketing can last for decades, providing long-term reinforcement and durability to RCC columns.
Column jacketing is a general strengthening method, while steel jacketing is a specific type that uses steel to reinforce and protect columns.
The thickness depends on structural design requirements, but typically ranges from 6 mm to 12 mm or more based on load and damage conditions.
