Abstract: A super-tall building with 31 floors and a total height of 144.55m adopts frame-supported shear wall structural system with high-level conversion part. The project preliminary design idea, out-of-code condition, performance-based seismic design, specific analysis on high-level conversion structure and the corresponding structural strengthening measures were described. In specific analysis, check calculation of the stiffness ratios of upper and lower layers to the structural conversion layer, the application of section steel components in conversion members, out-of-code analysis of upper wall of conversion layer, ultimate bearing capacity calculation of frame-supported members were introduced. The results show that the stiffness ratios of upper and lower layers to the structural conversion layer can be effectively increased by using the space of equipment conversion to increase the height of the upper layer of conversion layer and calculating the height according to the beam stiffness point; the use of section steel conversion beams and columns can make structural members meet the requirements of building space size and can also effectively solve the out-of-code problems of column axial compression ratio and out-of-code problem of shear capacity of shear wall in the upper layer of conversion beam. 

Keywords:out-of-code structure； frame-supported shear wall structure； high-level conversion； performance-based seismic design
