Design of viscous dampers based on minimization of first floor interstorey drift
In this study,a viscous damper optimization method is presented for a shear frame.Band limited white noise excitation is employed with constant density.Power Spectral Density(PSD)function of earthquake excitation is taken into consideration.Using the random vibration theory,the mean square response of interstorey drift of first floor is taken as objective function to be minimized considering both upper and lower limits of dampers.After finding optimal damping coefficient of dampers and their optimum distribution,shear building with added damper is tested with El Centro earthquake acceleration record.Findings for each storey is compared to other studies available in the literature with respect to storey displacement depending on time as well as their maximum peak values,Interstorey Drift Ratio(IDR),the root mean square of displacement(RMSD)and the root mean square of acceleration(RMSA)values.The results show that the outcomes of each study are almost the same and optimal damper placement at shear building is very effective in order to reduce the disturbance effect on the structure.
