Seismic analysis of the hung curtain wall structure in Shanghai Center Tower

摘要

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