Abstract:The key issues of structural design of complex super high-rise buildings over 250m were analyzed, including optimization analysis of structural column network, side-resistant structural system, structural materials, and crown structure. During the structural design process, ABAQUS, YJK software were used to carry out special analysis on key components such as through-story columns, unclosed frames, inclined columns and joints. Through calculation and analysis, it is ensured that the structural design is reasonable, the overall safety requirements are met, and the mechanical performance of each component reaches the expected goal.

Keywords:Guangzhou International Cultural Center； super high-rise structure; structural scheme optimization; inclined column analysis; unclosed frame analysis; creep analysis
