Vibration Energy Dissipation Analysis of a Shear Wall Structure

This paper studied on vibration energy dissipation analysis of a shear wall structure with viscous liquid dampers for reinforcement and reconstruction. Viscous liquid dampers and herringbone steel shotcrete were used for seismic control and the elastic-plastic time history analysis had been carried out. The results show that: the first layer shear force decreases. The minimal average damping rate of layer displacement in X direction is 4.68% and the maximum is 12.92%; the minimal average damping rate of layer displacement in Y direction is 6.47% and the maximum is 19.8%. So using viscous fluid dampers , the vibration response of the structure could be effectively reduced．
