Enhancing seismic performance of structures: A comprehensive review of hybrid passive energy dissipation devices
When an earthquake occurs, a substantial amount of elastic strain energy is released, and its intensity is typically measured by Peak Ground Acceleration (PGA). Installing dampers in buildings is a recognized method for dissipating this energy. Passive energy dissipation devices perform effectively under both high and low PGA conditions. Hybrid dampers combine two or more devices into a single unit and are designed to overcome individual weaknesses and enhance overall strength. This study provides a comprehensive review of hybrid passive energy-dissipating devices, emphasizing their crucial role in enhancing the seismic performance of structures. Hybrid dampers are instrumental in reducing roof displacement, drift, inter-story movement, floor acceleration, and base shear, thus significantly improving seismic resilience. The review also outlines various types of devices that are combined to create hybrid dampers, highlighting their importance in ongoing research. Despite numerous numerical analyses and experimental tests, research into implementing hybrid dampers in concrete structures remains limited. Consequently, there is a significant opportunity for improvement, design, development, and implementation of hybrid damping devices in buildings. These devices offer superior vibration control characteristics, making them an attractive option for enhancing the overall structural stability of structures.
