In this study, the probability of failure of steel frames with Tuned Mass Damper (TMD) is investigated. A 20‐story steel frame was designed using SAP software and then, it was modelled in OpenSees. The behaviour of the frame towards accelerations in the range of 0.1 to the maximum acceleration of seismic records was investigated in this study. Using Incremental Dynamic Analysis (IDA) and extracting seismic fragility curves, it was observed that TMD increased the stability of the structure against the earthquakes by absorbing the input energy to the structure. This significantly reduces the possibility of failure due to small PGAs. For example, for the acceleration scheme equal to 0.35 for Tehran (the capital of Iran), the probability of failure in all stories of the structures equipped with TMD will be insignificant.
