Abstract:

According to the construction challenges of the super⁃heavy and large⁃span curved steelstructure connecting corridor between the twin towers of the Shenzhen Super Headquarters Base Tower Cproject, a ground assembly construction technique is summarized. The approach involves reinforcing theground bearing capacity, setting pre⁃cambered distribution beams to rationally transfer loads to the lowerconcrete columns, and implementing full⁃process precision control through physical pre⁃assembly and 3Dlaser scanning technology. Furthermore, construction numerical simulation is utilized to analyze thedeformation and stress of the connecting corridor truss, the mechanical behavior of the distributionbeams, and the stress state of the lower concrete columns. The results indicate that this technical systemeffectively ensures the safety, stability, and forming accuracy of the corridor structure assembly.
