Challenge in the Structural Design of Suzhou IFS

초록

Core-outrigger-mega frame system is used in a 95-story, 450 meters-tall Suzhou IFS, which is beyond Chinese code limit.

Besides simple introduction on design principle, presented in this study are structure system and analysis, key techniques including performance-based design criteria, frame shear ratio, capacity check of mega column, human comfort criteria under wind induced vibration and TSD design, all of which are presented in details for reference of similar super-tall building design.
