Abstract:Compared with the traditional seismic scheme, the energy-dissipated scheme can effectively increase the energy dissipation line of the structural system and improve the seismic performance of the main structure by adding energy dissipation devices. Based on a practical 310m super high-rise project in the 8-degree high seismic precautionary intensity area, the comparison selection, parameter optimization and energy dissipation effect analysis and evaluation of the energy dissipation devices in the energy-dissipated scheme were carried out. The similarities and differences of two different structural systems of traditional aseismic scheme  and energy-dissipated scheme  were discussed, and the calculation and analysis were conducted under different fortification levels of earthquakes, and the advantages of energy-dissipated scheme were illustrated from the aspects of overall structure index, seismic performance and economy.

Keywords:super high-rise structure; high seismic precautionary intensity area; energy dissipation; viscous damper
