Abstract:Avic Capital Building with 43-story, 220m-tall, is a high-rise office building, including the characters of height exceeding limitation and plane and vertical irregular. The concrete filled steel tube column frame and steel reinforced concrete-encased core wall and belt truss and steel floor beam and cast-in-place floor slab were adopted. The structural system and foundation were introduced, and the solving methods of main problems about across the floor pillar and shear wall tensile stress action were also mainly introduced. The principles and methods of performance-based seismic design were introduced by the project on structure overlimit situation. To calculate and analyze the overall calculation results of frequent and intermediate earthquake, the static elastic-plastic ultimate seismic analysis under rare earthquake，as shown in the results, the objective of performance design is reasonable, and the structure is safe and reliable.

Keywords:Avic Capital Building; concrete filled steel tube column; structural system; tensile stress; belt truss; performance-based seismic design
