Abstract: The Poly Commercial Central Tower with the height of about 252m adopts frame-core wall structural system. The project is an out-of-code super high-rise structure. According to super high-rise structure, large span and heavy load roof, super altitude monolayer cable curtain wall structure and other key issues, a variety of structural analysis including elastic analysis, elasto-plastic analysis and component damage analysis under the long-period seismic wave were carried out. The corresponding seismic strengthening measures which ensure the structural performance meets the seismic performance goal.

Keywords: super high-rise structure; seismic performance; elasto-plastic analysis; long-period seismic wave; super altitude cable curtain wall
