- Abstract
- This paper introduces a new steel-jacketing method for reinforced concrete (RC) columns using external pressure. Experimental tests of concrete cylinders and RC columns are performed to assess the effectiveness of the proposed method. Single-and double-layered Jackets are introduced. The newly jacketed cylinders show good results in terms of increasing the compressive strength and ductility compared to plain cylinders. The double-layered jackets are estimated to show equal performance to that of a single steel jacket having the same thickness as the double-layered jacket. Four columns are prepared and two of them are confined by steel jackets with external pressure; one is a single-layered jacket and the other is a double-layered jacket. The proposed steel-jacketing method increases the ductility of lap-spliced RC columns. The double-layered jacketed column produces more ductile behavior than the single-layered jacketed column.
