RC Columns Strengthened with Novel CFRP Systems: An Experimental Study

This paper presents an experimental study undertaken to investigate the seismic behavior of full scale square (300 mm × 300 mm) reinforced concrete (RC) columns strengthened with novel systems employing carbon fiber-reinforced polymers (CFRP) wraps. Experimental tests were carried out by subjecting...
