［摘要］騰訊濱海大廈通過桁架實現(xiàn)了大跨度多道連接體。與此同時，桁架在匯交節(jié)點上連接的桿件數(shù)目較多，節(jié)點受力及構(gòu)造非常復(fù)雜，初步設(shè)計階段，匯交節(jié)點采用鑄鋼節(jié)點。后對鑄鋼節(jié)點進(jìn)行了優(yōu)化，采用鋼骨混凝土柱過渡至鋼管混凝土柱的匯交過渡節(jié)點。通過采取相應(yīng)的構(gòu)造措施，匯交過渡節(jié)點可以良好實現(xiàn)鋼板、鋼筋、混凝土的連續(xù)性，受力傳遞可靠。和鑄鋼節(jié)點相比，匯交過渡節(jié)點還能極大地減輕節(jié)點重量，降低制作、安裝成本，縮短工期。此外，采用ABAQUS及ANSYS軟件對匯交過渡節(jié)點進(jìn)行有限元受力分析，計算結(jié)果表明，節(jié)點設(shè)計能滿足既定性能目標(biāo)及“強節(jié)點、弱構(gòu)件”的要求。

Abstract:Tencent Seafront Tower has realized multiple large-span connections through trusses. At the same time, the number of components connected to the truss at the transition joint is large, and the stress and structure of the joint are very complicated. In the preliminary design stage, the transition joint adopted a cast steel joint. The cast steel joints were optimized, SRC-CFT transition column joint were used. By adopting corresponding structural measures, the transition joint could achieve the continuity of steel plates, steel bars and concrete, and the force transmission was reliable. Compared with the cast steel joint, the transition joint could greatly reduce the weight of the joint, reduce the manufacturing and installation costs, and shorten the construction period. In addition, ABAQUS and ANSYS software were used to analyze the finite element stress of the transition joint. The calculation results show that the joint design can meet the requirements of the established performance objectives and the “strong joint and weak component”.
Keywords:Tencent Seafront Tower; transition joint; cost of production and installation; component continuity; finite element analysis; performance objectives
