［摘要］珠西金融中心1#綜合樓結(jié)構(gòu)總高度為336m，地上70層，地下3層，因核心筒截面尺寸限制，建筑單向體型收進較大，此外還存在地基承載力偏低以及沿海風(fēng)壓較大等設(shè)計難點，采用了一種新的帶加強層的鋼管柱框架-排鋼管鋼板混凝土剪力墻核心筒結(jié)構(gòu)體系。重點介紹了新型的排鋼管鋼板混凝土剪力墻截面構(gòu)造形式及與墻、梁、板的連接節(jié)點，超高層基礎(chǔ)設(shè)計及沉降控制，環(huán)形加強帶設(shè)計，關(guān)鍵節(jié)點（鋼筋混凝土梁-鋼管柱連接節(jié)點以及分叉柱節(jié)點）的設(shè)計。計算結(jié)果表明，關(guān)鍵節(jié)點符合規(guī)范及安全性驗算的要求。

Abstract: The 1# comprehensive building of Zhuxi Financial Center has a total height of 336 meters, 70 floors above ground and 3 floors underground. Due to the limitation of the cross-sectional size of the core walls, the building has a large one-way body shape, In addition, there are design difficulties such as low foundation bearing capacity and high coastal wind pressure. A new core tube structure system with strengthened story, the steel tube column frame-row steel tube steel plate concrete shear wall was adopted. The new row steel tube steel plate concrete shear wall construction shape and the connection joints with wall, beam and slab, super high-rise foundation design and settlement control, annular strengthened belt design, and the design of key joints（reinforced concrete beam-steel tube column connection joint and bifurcation column joint）were mainly introduced. The calculation results show that the key nodes meet the requirements of the specification and safety check calculations.
Keywords:super high-rise building； steel tube column frame-row steel tube steel plate concrete shear wall； composite structure； soft soil foundation； key joint
