Fluid viscous dampers can be utilized to control structural vibration as well as to meet the requirements of structural stiffness and strength under both wind and seismic excitations. As they can operate with a wide range of excitation frequencies, a double-excitation vibration mitigation system is introduced. Moreover, various deformation amplification devices, double dampers configurations, and fluid viscous damper parameters are comprehensively analyzed for the system selection for wind and seismic excitations. Using the sensitivity analysis method, structural optimization with the proposed system is demonstrated in the case study of a tall steel residential building. |
