超高顶部大悬挑钢-混凝土组合结构施工技术

Construction Technology of Large Cantilever Steel-concrete Composite Structure at the Top of Super-high

随着超高层建筑的发展,传统混凝土结构越来越难以满足人们对大空间、多样化和复杂化立面体型的需求,相比传统混凝土结构,钢-混凝土组合结构具有承载力高、刚度大、抗震性能好、施工快速方便、可利用空间大等优点,越来越受到人们的重视。对于一些设计顶部"凹入"或部分"凹入"的悬挑钢-混凝土组合结构或钢结构,采用该技术可保证施工安全,节约施工工期和施工成本,应用前景广阔。

With the development of super high-rise buildings,traditional concrete structure is more and more difficult to meet people＇s demand for large space,diversification and complex facade,compared with traditional concrete structure,steel-concrete composite structure has the advantages of high bearing capacity,large stiffness,good seismic performance,fast construction and convenient,and great space for use,which is paid more and more attention by people. For some cantilever steel-concrete composite structures or steel structures with ＂concave＂ or ＂concave＂ in the top of the design, this technology can guarantee the construction safety,save the construction period and construction cost,and have a broad application prospect.
