| Abstract: |
A new steel jacket is proposed for retrofitting of circular reinforced concrete short columns. The installation of this jacket saves time, labor and cost in comparison to available jacketing systems. The assembly procedure would induce active confinement on the concrete column. Retrofitted column would be credited with the advantages of concrete-filled tubular columns The jacket can be utilized for the repair and strength of already existing columns and for new work regardless of column loading state; i.e. loaded or unloaded. A total number of 17 cylindrical short columns were tested under concentric axial loads until failure. Concrete axial strength was increased in value more than twice. The results obtained are presented in tables 3 and 4. Design method. |
