Abstract: C Tower of EVERGRANDE International Center with the height of 174.4m and 42 floors on the grand, uses the frame-shear wall structure system and the standard L-shaped plane layout. Firstly, combined architecture scheme and economic analysis, the structural system selection of the main structure is explained in this paper. Then, the calculation measures and the design measures about the plane irregularity, the vertical irregularity and the other irregularity of the structure systematically were introduced. At the same time, the performance design method of the structure particularly was stated. Finally, supplement calculation method and structure strengthening measures about the key component of the structure were emphatically presented. Research and design results show that, by using reasonable computational measures and design measures, the irregularity of the original structure has been effectively controlled, and the structure calculation index can better meet the requirements of the standards. The structure is safe, reliable and the structural design is feasible.
