The objective of this case study is to investigate the structural failure of a 20-year old building due to local buckling of a reinforced concrete (RC) column at lower floor. Firstly, the stress history of the concrete and steel rebar in the column is reproduced through analysing the core samples. Secondly, the buckling event is simulated using the computer code, LS-DYNA. The failure mode was successfully reproduced. The simulation would show the process of concrete spalling and buckling of steel re-bars. It agreed well with the failure scene.
