Although the collapse of structures and loss of life caused by natural hazards have been effectively controlled in the last two decades, the economic losses caused by them continue and are considered one of the main concerns in the discussion of the resilience of urban areas. Since the earthquake is one of the most destructive natural disasters, the damages caused by it have been discussed in this study. FEMA P-58 has provided a method for estimating earthquake damage. In this method, damage assessment has been done at the component level and access to this level of information is the main challenge of using this method. Today, building information modeling (BIM) has been proposed as one of the new and powerful tools in the design and construction of structures, which leads to the production of a valid database throughout the project's life cycle. Therefore, building information modeling can be considered as a solution to the challenge of FEMA P-58 seismic damage assessment method. On the other hand, the heartbreaking events that have occurred in recent years have forced researchers to examine a new concept as resilience and change their attitude from the side of vulnerability and assessment of possible risks, to a new attitude in which many It has included social from other areas. In this thesis, for the first time, the combination of FEMA P-58 and BIM method has been used to eva‎luate the seismic resilience of a steel frame building. For this purpose, a school with convergent bracing system located in Tehran city was selected as a study sample and was modeled in Revit software. Then, using Etabs software, it was subjected to nonlinear dynamic analysis under the effect of earthquakes in the nearby area, and using PACT software and the mathematical functions available in it, the fragility curves of structural and non-structural components and The amount of damage caused to them has been assessed. In fact, the results obtained from Etabs and Revit software were entered as data in Pact software, and finally, the effects of detail modeling on resilience index in five different seismic acceleration g 0.125, g 0.512, g 8 0.0, g 0.1 and g 1.15 were investigated. The calculated results show that the modeling of intermediate frames causes an increase of 1-7% of resilience and the modeling of non-structural elements causes a decrease of 1-15%, and the modeling of the columns does not cause a noticeable change.
