Abstract:
Based on the C block project of Xuzhou Deji Plaza, this paper studies the constructiontechnology of large space urban complex reconstruction caused by the improvement of function andstructural performance. The reconstruction mainly involves the seismic performance enhancement of superhigh?rise structures, the internal shrinkage of super high?rise core core tubes, the internal layoutadjustment of commercial podiums and basements, and the changes in the shape of the buildingperiphery. The vertical members of the east tower 10——12 floors core tube are inclined to shrink by 2m,which avoids the sudden change of the wall vertical stiffness and increases the indoor area of each layer.The oblique steel plate shear wall of the east tower is adjusted to the rigid column shear wall to improvethe stiffness of the structure and meet the requirements of oblique construction. Measures such asremoving the original structure, pasting steel plates, pasting carbon fiber cloth, expanding the crosssection of beams and columns, adding shear walls, adding beams and slabs, and set columns on beamswere adopted to complete the commercial podium and basement functional improvement, layoutadjustment and building peripheral modeling changes.
