Sensitivity of lift core positions for T-shaped reinforced concrete buildings subject to seismic loads

T-shaped buildings are classified as buildings with plan irregularity and vulnerable to damages under seismic loading. This study investigates the sensitivity of lift core positions by comparing the percentage difference of the maximum torsional moment and building deformation for T-shaped reinforced concrete buildings. Building models having 6-storey and 12-storey were generated and analysed with the aid of SAP2000 software package. The results showed that the locations of the lift core significantly influenced the magnitude of the torsional moment and particularly true for all building heights. It is highly recommended that the position of the lift core must be carefully determined in order to reduce or arrest the failure associated to torsional moment
