Examination of the damage caused by past earthquakes, such as the Kermanshah earthquake, confirms that infilled-frame buildings, which were built on soft soil, experienced more damage than these buildings on site with hard soil. One reason for this damage is ignorance of the effects of masonry infill on the behavior of the structure, despite the recommendations of seismic codes. Therefore, in this research, the effect of the presence or absence of masonry infills on the seismic performance of steel moment-resisting frames with considering the effect of soil-structure interaction has been investigated. In this regard, incremental nonlinear dynamic analyzes were performed on two-dimensional frames with 3, 6, 9, 12, 15, and 20 stories and three bays, which were designed in soil type B o based on Eurocode-8. For this purpose, 21 far-field ground motions were selected according to the FEMA-P695 and time history analyses were performed in SeismoStruct. Also, the effects of soil-structure interaction on both rigid and flexible substrates were considered. Then, probabilistic evaluation of the frames was performed by obtaining the seismic fragility curves in immediate occupancy (IO), life safety (LS), and collapse prevention (CP) performance levels. The results showed that the presence of infill panels reduces the vulnerability of structures, especially by increasing the frame height. The spectral acceleration required to create collapse prevention performance increases from 1.2 to 3 times. However, considering the effects of soil-structure interaction in the estimation of structural capacity is more reliable and leads to the more realistic capacity estimation of structures.
