Advancements in Seismic Isolation Technologies for Super High-rise Buildings

Abstract

With the progress of modern building technology and the rapid development of social economy, super high-rise buildings have become an important part of urban landscape, and the number and height of construction in the world are rising. Therefore, it is particularly important to ensure the safety of these buildings and their internal facilities, especially the seismic performance in earthquake-prone areas. In this context, seismic isolation technology has been widely used as an effective seismic solution. The traditional seismic design method mainly resists the earthquake by enhancing the strength and stiffness of the structure itself, while the damping or shock insulation reduces the impact of the earthquake on the building by introducing energy-consuming components or isolation layers. In addition, seismic isolation is the hybrid systems of damping and shock insulation, which combines the advantages of both. Compared with a single method, which not only reduces the energy dissipation, but also improves the overall stability of the structure, and provides a more comprehensive and efficient guarantee for the seismic design of super high-rise buildings.
