Zigzag giant column frame-core tube structure system adopting bidirectional dense rib floor system

The invention discloses a zigzag huge column frame-core tube structure system adopting a bidirectional dense rib floor system, which is characterized in that turning joints are arranged at floor system positions of turning floors, and the bidirectional dense rib floor system is adopted as the floor system of the turning floors; the transverse rib beams are parallel to two of the four large-span frame beams, corresponding to the turning floors, of the outer frame, and the longitudinal rib beams are parallel to the other two of the four large-span frame beams; an inner ring solid part is arranged between the inner side edge of the rib beam part and the core tube, and an outer ring solid part is arranged between the outer side edge of the rib beam part and the turning joint of the outer frame at the corresponding turning floor and the frame beam, so that concentrated horizontal force of the frame column at the turning joint is more uniformly and effectively transmitted; the redundancy of the frame-core tube stru
