Abstract
The intensity-reduced method based on fluid viscous dampers is proposed in this study. The analysis model of fluid viscous dampers is firstly introduced. The intensity-reduced design procedure is thoroughly discussed. Taking an 11-story reinforced concrete frame shear-wall structure as example, the intensity-reduced method is implemented in this study. The dynamic responses of the structure with and without fluid viscous dampers, including the maximum inter-story drift angle, base shear force, are discussed. The results show that the proposed intensity-reduced method for structure with fluid viscous dampers is feasible, and the responses of structure satisfy the code for seismic design of buildings. The earthquake input energy is mainly dissipated by fluid viscous dampers, which guarantees the safety of the main structure.
