?中建五局科技研發(fā)課題：大空間城市綜合體功能提升結(jié)構(gòu)改造關(guān)鍵技術(shù)研究（CSCEC5b?2022?72）摘要：
以徐州德基廣場(chǎng) C 地塊項(xiàng)目為依托，研究滿足功能提升及結(jié)構(gòu)性能提高的大空間城市綜合體改造施工技術(shù)，主要涉及超高層結(jié)構(gòu)抗震性能增強(qiáng)、超高層核心筒內(nèi)縮、商業(yè)裙樓及地下室內(nèi)部布局調(diào)整和建筑外圍造型變化等。東塔樓 10—— 12 層核心筒豎向構(gòu)件斜向收縮 2m,逐層內(nèi)收，避免墻體豎向剛度突變，并增加每層外圍戶內(nèi)面積。將東塔樓斜向鋼板剪力墻調(diào)整為勁性柱剪力墻，提高結(jié)構(gòu)自身剛度，滿足斜向施工要求。采取原結(jié)構(gòu)拆除、粘貼鋼板、粘貼碳纖維布、擴(kuò)大梁柱截面、新增剪力墻、新增梁板、新增梁抬柱等措施完成商業(yè)裙樓及地下室功能提升、布局調(diào)整與建筑外圍造型變化。

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.
