ENERGY DISSIPATION PERFORMANCE OF OUTRIGGER IN TALL BUILDINGS

  • The outriggers are the key components of super-tall structures. Increasing the energy dissipation capacities of outriggers is of a great significance on improving the structural aseismic performance. The commonly used outriggers include regular outriggers, buckling restrained braces (BRB) outriggers, and outriggers with dampers. Based on a super-tall frame-core-outrigger structure, the energy dissipation and aseismic performance of regular outriggers, buckling restrained braces (BRB) outriggers, and outriggers with dampers are investigated and compared. The results indicate that different outriggers have some impacts on the seismic energy input and energy distribution of the structure. Compared with the ordinary outrigger system, the BRB and damped outrigger systems have better energy consumption performance. In addition, the damped outrigger has a more obvious effect on the damage control of the core cylinder, while the BRB outrigger has the best effect in the displacement response control for the overall structure of a super-tall building.
