SUMMARY Shanghai Center Tower, which is 632 m in height with 126 stories, will be the tallest building in China at the end of 2014. The extreme height of the building combined with the exterior shrink‐constructed and torsion‐constructed curtain wall imposes a great challenge on the seismic design of the curtain wall. This paper establishes a finite element (FE) model of the real‐scale building by considering the combination of the curtain wall and the main structure. The lower order modes of the building's vibration have been predicted, and good agreement has been observed between the numerical and experimental data, which validates the FE model of the building. Seismic response of the curtain wall was then investigated under three earthquake levels, including frequent, moderate and severe earthquakes. The acceleration magnification factors, the inter‐story drift ratios and the interior forces of the curtain wall met the requirements of the Chinese Design Code, which indicates that the structure is a good solution to withstand earthquakes. The present study provides an important database for the seismic design of curtain wall structure in Shanghai Center Tower, and it can be used as a seismic design reference for similar projects.
