Effectiveness of fluid viscous dampers in the seismic performance enhancement of RC buildings
The usage of the passive energy dissipative system is increasing nowadays in the high seismic risk zones, particularly in the important buildings. In this context, the effectiveness of the nonlinear fluid viscous dampers (FVDs) in the seismic performance enhancement of RC buildings is analysed in this study. This research compares the engineering response parameters such as total displacement, drift ratio, residual displacement and the floor acceleration between bare frame only model and the same with the addition of nonlinear fluid viscous dampers for Design Basis Earthquake (DBE) and Maximum Considered Earthquake (MCE). The study is done in three categories of regular buildings from the perspective of Nepalese cities; five-storeyed, ten-storeyed and fifteen-storeyed buildings as this covers the typical high-rise buildings in Nepal. The building is modelled in the 3-D finite element analysis software SAP2000 developed by Computers and Structures Inc. The results show that nonlinear fluid viscous dampers are highly effective in reducing the storey displacement, drift and residual displacement whereas less effective in reducing floor acceleration as compared to the others and the efficacy of the dampers reduces with increasing building height.
