Abstract:The structural designs of C and D tower buildings and the super large-span connected structure in the business center of Fuzhou East New City were introduced. Four connected design schemes  bottom support scheme，bottom cap lifting scheme，integral vierendeel truss scheme and integral support scheme were compared and analyzed from the perspectives of internal force, cross-section, connected body stiffness, economy and overall coordination. The design concept of connected structure of mega double-web H-typed cross-section member was proposed, and the reasonable connected structural form was selected, providing reference for similar structural design.

Keywords:super large-span connected structure; scheme selection; integral support; mega double-web H-typed cross-section member
