Abstract:The super high\|rise building 1# of No.C03-3 Plot in Gangxi District of Dalian is joined by three units at corners, and it adopts RC shear wall structure. The main content of the out-of-code design was introduced in detail. The mechanical features of the shear wall structure with special plane under earthquake action were analyzed. The corresponding measures were put forward to tackle obvious torsion effect caused by eccentricity. The floors in the corner of weak parts and at the waist parts were reinforced. Changes of position of tensile shear walls under different earthquake actions were concerned and relevant performance-based seismic design was carried out. The results of performance-based seismic design of the structure show that the structure can meet the expected seismic performance objectives.

Keywords:super high-rise building; seismic performance objective； structure with special plane; seismic design
