Abstract
Past earthquakes in Iran have caused severe damage to existing steel buildings without adequate resistance and ductility against earthquakes. Competent methods for seismic retrofitting are required in order to prevent damage and casualty. Among effective seismic retrofit methods, passive control reduces seismic vulnerability by mitigating seismic demand and increasing ductility. One of the most suitable methods in passive control system is to use pall friction damper in the braced steel structures. Main advantage of this friction damper is its almost rectangular force-deformation hysteretic loops with high-energy dissipations, without any need to specific technology. In this paper, while introducing the performance of pall friction dampers and their design, seismic retrofit of an existing 4-story steel simple frame in Iran is investigated by using such dampers.
