Seismic Retrofitting of Reinforced Concrete Buildings with Rotational Friction Dampers
The recent earthquakes in Türkiye have caused massive destruction to many buildings and structures, particularly reinforced concrete buildings which were not sufficiently engineered to withstand major seismic events. This paper presents a seismic retrofit using Rotational Friction Dampers, a supplemental energy dissipation device that can be installed during the normal function of the structures. The most effective damper configuration and capacities were selected after an iterative trial-and-error linear study using simplified methods developed by authors. Nonlinear push-over and time-history analyses are also conducted for confirmation of results. The proposed retrofit scheme satisfies desired performance goals for both DBE and MCE events. It provides the optimal solution for stakeholders from a performance, design, constructability, and economical point of view. The paper includes application photos and explanations of the retrofit methods used. Overall, rotational friction dampers provide passive energy dissipation and protect buildings from structural and nonstructural damage during moderate and severe earthquakes. It is worth noting that testing of dampers of this type with different slip capacities has been carried out at the Technical University of Denmark and other Japanese and USA laboratories over the last two decades, providing a solid basis for their use in seismic retrofitting. Additionally, at the time of this paper, more than 25 different structures and buildings in Türkiye have been retrofitted with Rotational Friction Dampers. The paper concludes that retrofitting with Rotational Friction Dampers is a viable solution for earthquake protection of precast reinforced concrete structures.
