Designing buildings with appropriate resilience to minimize seismic damage to structures is a method that ensures buildings can be rapidly restored to their intended functional purposes after a major earthquake. Examples of this technology include buildings incorporating special connection details, energy dissipation mechanisms, an‎d base isolation techniques. Currently, resilience-based seismic design of buildings using seismic isolation systems has become a critical topic. Seismic isolation plays a significant role in achieving high resilience against earthquakes an‎d reducing earthquake-induced damage. The ultimate goal of this thesis is to eva‎luate the seismic resilience of mid-rise steel moment-resisting frames equipped with a triple friction pendulum bearing system. To achieve this objective, a three-dimensional model of a three-story steel building has been developed in OpenSees for two seismic hazard levels: the design basis earthquake (DBE) an‎d the maximum considered earthquake (MCE). In the design of this model, the force-based beam-column element has been utilized. For the analysis phase, the created models have been eva‎luated for their seismic behavior using time history analysis an‎d Incremental Dynamic Analysis (IDA). To examine the modelʹs behavior, various earthquake records from far-field an‎d near-field seismic events, all compatible with the site conditions of the model, have been selec‎ted. In this dissertation, in addition to estimating the resilience percentage of the structure equipped with the triple friction pendulum bearing system, various parameters such as interstory drift ratio, absolute floor acceleration, base shear, fragility curves, an‎d resilience levels have been analyzed an‎d compared for both fixed-base an‎d isolated structures.
