Interlocking Column I2_P - Biaxial Bending + Axial Force + Biaxial P-delta effects+ Torsion

Oval shaped reinforced concrete column tested on shake table with the Bidirectional Mass Rig (BMR). This column was tested with axial force and p-delta effects. The mass was placed assymetrically on the BMR to induce torsion in the column. The ground motions input were from the 1994 Northridge earthquake from the Sylmar station in California. The test was conducted in 10 stages using varying intensities of the input motion from a scale factor of 0.1 in the first run to 1.6 in the second to last run. The last run was another run of the 1.6 magnitude labeled 1.6Final.
