Drift investigation of limited ductile RC columns under biaxial bending

The seismic drift capacity and collapse performance of two axially loaded full-length limited ductile reinforced corner column was investigated under biaxial lateral loading using quasi-static cyclic and pseudo-dynamic hybrid testing approach under real earthquake excitation. Furthermore, the effectiveness of carbon fibre reinforced polymer sheets of the strengthened earthquake-damaged limited ductile column was evaluated experimentally. While limited ductile reinforced column have been widely constructed in low to-moderate seismic regions like Australia, the corresponding collapse analyses are limited. Formulae for estimating the drift capacity and lateral load-drift behaviour of limited ductile corner column subjected to biaxial demands were developed.
