Passive Electromagnetic Damper is a new type of damper that can be used as an alternative as a tool to improve structural performance in carrying earthquake loads which is one of the biggest challenges in infrastructure designing in Indonesia. Passive electromagnetic dampers offer advantages that other types of dampers do not have, including flexibility in adjusting the desired damping capacity and dissipated energy that can be stored in the form of electricity the dissipated energy does not damage the dampers due to self-heating that will occur if the energy is dissipated in the form of temperature increase. Two structural models are created to see structural behavior with and without passive electromagnetic dampers. The structure used is a 30-story steel frame structure that functions as an office and is located in Bandung City. The steel profile used is WF 608 x 477 for columns and IWF 650 x 300 for beams. The profile is determined by iterations with a specific target of strength and rigidity. The passive electromagnetic damper used is assumed to behave linearly with a damping coefficient of 906 kN-s/m. From response spectrum and time history analysis, it was found that the structure without dampers did not pass the earthquake resistant building conditions required in SNI 1726:2012, while the structure equipped with passive electromagnetic dampers with certain configurations escaped all earthquakeresistant building requirements. Overall, the addition of passive electromagnetic dampers with the configuration used decreases the structure period by 8.15 percent, the average story drift by 15.85 percent, the average interstory drift by 6.81 percent, and the average ? (parameter of the P-Delta effect) by 13.84 percent.
