| description | The application of damping amplification technology to dampers can effectively enhance the energy dissipation efficiency and address the issue of underutilization during small displacements. In this study, a novel horizontal universal damping amplification device (HUDAD) is proposed, and its construction and operational mechanism are detailed. A restoring-force model for the horizontal universal viscous damping amplification device (HUDAD-VD) is derived, which integrates viscous dampers, establishing its equations of motion and energy balance. Furthermore, pseudo-static tests are conducted to validate the damping amplification and energy dissipation capabilities of the HUDAD-VD. Finally, a seismic response analysis of a multi-degree-of-freedom damping system incorporating the HUDAD-VD is performed to evaluate its seismic performance. The results show the close alignment between the experimental and theoretical hysteretic curves of the HUDAD-VD, confirming the accuracy of the theoretical model. The HUDAD-VD demonstrates effective damping performance under all levels of seismic action, successfully controlling the displacement within the seismic isolation layer. In particular, the HUDAD exhibits a satisfactory amplification effect, effectively enhancing the damper energy dissipation. |
