Abstract:The T2 tower of Dongguan International Trade Center is a mixed uses of commercial and office, soaring up to 428.8 meters height. It uses frame composed with CFT column and steel beam + core +outriggers structural system. The following design focuses were illustrated: structural system and its characteristic, the seismic performance objectives of structural members, the design of key joints, the control and evaluation of structural overall index, measures and detail principal of seismic design.
Keywords:ultra limit high-rise building; CFT column; performance-based design; outrigger; rotated column; rigidity-gravity ratio
