Abstract: This analysis and design of an out-of-code high-rise building in Shanghai were introduced detail. Several out-of-code characteristics exist in structure, including torsion irregularity, discontinuous floor and discontinuity of lateral-resisting components. Foundation design, out-of-code characteristics and corresponding seismic measures were introduced. The results of the elastic analysis, elastic time-history analysis, slab stress analysis, moderate earthquake analysis and rare earthquake analysis show that all the indices can meet the code requirements.

Keywords: out-of-code high-rise structure; elastic time-history analysis; slab stress analysis
