Steel Plate Jacketing

Steel Jacketing is a technique where the retrofit is done with steel to structural elements. The principle behind this technique is that the steel jacket acts as a passive confined reinforcement. It has been widely used as a strengthening technique to enhance the shear capacity and ductility of beams and columns.


  • To increase the flexural strength of the structural member
  • Prevents the concrete from dilating, forcing it in lateral compression and increasing its compressive strength
  • Increases its effective ultimate compressive strain and its ductility
  • Ease for working, reduction of dead load and cross-sectional area.
  • The gaps are filled with non-shrink grout.
