The document discusses the structural analysis of seismic friction dampers. It summarizes that friction dampers are installed in buildings in a way that their moving parts slide during earthquakes to dissipate seismic energy. Two building models are analyzed using pushover analysis: a rectangular building with rectangular columns and dampers, and a rectangular building without dampers. The results show that the building with dampers experiences lower lateral displacements, base shear, and story drift compared to the building without dampers under earthquake loading. Friction dampers thus help improve a building's seismic performance by reducing its response.
