Steel Pipe Retrofitting Method to Enhance the Seismic Performance of RC Column Under Combined Load

ABSTRACT A reinforced concrete column is subjected to a combination of axial load, lateral load, and torsion during earthquake excitations. Torsion induced under combined load can result in brittle failure in these columns. This study introduces a retrofitting technique using steel pipes designed to...
