In terms of earthquake disaster mitigation, one thing that needs attention in structural engineering is developing concepts to improve structural performance and safety level of existing building due to earthquakes. This study combines findings among the effectiveness of passive, active and semi-active controls systems. The first part of this paper describes the seismicity in Asian region, the second part discusses methods of energy dissipation, and the third part focus on low-rise building with dampers. It was found from references that the behavior of the semi-active control system shows better performance in seismic protection when compared to the passive control and active control systems. Passive control devices, when integrated into the structure will partially dissipate the input energy, thereby reducing the need for energy reduction in the main structural elements and reducing the structural damage. Base isolator can provide a good foundation for large and heavy structures that are located on hard ground against earthquakes. Base isolators and viscous dampers that work in a hybrid system can behave well under strong earthquakes. Semi-active control is the best in energy dissipation, but for easier and cheaper the purposes that are appropriate for Asian developing countries, passive control is more suitable for implementation. In addition, for the purpose of improving the performance of existing buildings, passive control is the best system applied to old and low rise buildings, that were built referred to old seismic code, without having to make major improvements to structural elements. Further numerical analysis and experimental programs specifically for existing buildings with recommended damping systems are needed in order to obtain verification for further application purposes. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
