Experimental observation on the seismic performance of reinforced concrete columns with a well-confined plastic hinge region

Abstract Seismic performance evaluation was conducted on eight circular reinforced concrete columns. Key design parameters for the columns included the number of longitudinal reinforcements, yield strength of reinforcements, vertical spacing of spirals, aspect ratio, and axial force ratio. Test resu...
