Abstract
Earthquake causes damage to many lives and properties. To decrease the effect of earthquake, energy dissipating devices are used for the dissipation of earthquake energy, due to which effect of earthquake on lives and properties get reduced. This study presents the Numerical investigation on the use of friction damper to connect two parallel structures. A numerical model (Viscoplasticity model) is used to model the friction forces in the damper. Seismic responses of single structure (SDOF) equipped with friction damper and two parallel structures (SDOF) connected with friction damper is calculated. The base excitation considered is Imperial Valley 1940 earthquake recorded excitation. A numerical model (Viscoplasticity model) is used to model the friction forces in the damper. The equations of motion are solved by Newmark’s step-by-step method. MATLAB computer program are generated to calculate the seismic response of connected structure under earthquake excitation. Result shows that when friction damper is used to connect two parallel structures, there is reduction in earthquake response.
Keywords- Energy dissipating devices, friction damper, parallel structures, seismic response.
