Earthquakes are among natural disasters that cause serious human and financial damage to structures. Our country, Iran, is not exempted from this rule due to its earthquake-proneness due to past earthquakes such as Khoi, Sarpol Zahab, Bam and Rudbar earthquakes. In this regard, engineers and researchers have pushed the design methods in a direction that is preventive. and to minimize possible damages. For this purpose, it is important to examine and eva‎luate the resilience of structures against earthquakes. In this regard, an example of a hospital in Noor city, whose skeleton is concrete, was selected. In this thesis, a bending frame with a shear wall was selected in each direction of the structure for modeling and analysis. And the basis for calculating resilience. FEMA P58 framework has been used. In this regard, the desired frames were first modeled in OpenSees open source software. and were subjected to nonlinear time history analysis. And the fragility curve corresponding to each frame was drawn. Then the results obtained from this analysis were given as input to PACT software. whose task is to assess the amount of damage caused to the components and the time required for repair. The reason for using PACT is that it extracts the mentioned items based on the same regulations. In this thesis, the 10% risk level in 50 years according to the 2800 standard was used to calculate the seismic resilience factor. After extracting the data, the performance curve corresponding to each of the frames was obtained. It was observed that the M frame suffered less damage than the 15 frame due to having fewer components. The M frame suffered 19% damage and the 15 frame was damaged by about 27%. It was also observed that the M frame required less time than the 15 frame to Full recovery is reached for frame M in about 112 days and frame 15 in about 153 days, which indicates that fewer components caused them to suffer less damage and recover in a shorter period of time. And finally, the resilience index obtained for 15 frame is around 93% and M frame is around 97%.
