Seismic Response Control of High Rise Mass Varied Structures using Friction Dampers

When a seismic event causes unwanted motion in buildings, energy dissipation techniques in civil engineering are required. There are a variety of structures with passive energy dissipation provided by Passive Constant friction damper systems (CFRD). This technique is being used more and more to increase seismic protection for both existing and new constructions. The CFRD system results are explored in order to compare the structural response with and without this device of energy dissipation compared for low and high rise mass varied buildings, the damper put at different storey and altering the slip force has been focused in this study which gives an insight into the variation of slip load and its locations. The CFRD's potential to boost the structure's dissipative capacities without increasing stiffness was discovered. In the case of high-rise buildings, CFRD performance has been examined using top-storey displacements, allowing for a conclusion.
