vivo全球AI研发中心钢结构施工关键技术研究OA

The vivo Global AI R&D Center project is an intricate building,featuring a steel frame core tube structure system comprised of five individual,box-shaped,large-span mega arches.The most prominent arch boasts a maximum span of 39 m,with a maximum width of 77.6 m.The construction is complex,including rare five-story basements with significant height variations and numerous openings.To overcome these challenges,a large crawler crane mounted steel trestle,and a support system was erected beneath the arches,facilitating sectional lifting from the interior outwards.This article mainly introduces the decision-making process behind selecting the construction scheme for the mega arch.A steel trestle suitable for heavy-duty crawler crane operations and a mega arch support system with tower crane standard sections as the main components were designed.The construction simulation analysis and construction health monitoring of the entire process of the mega arch were carried out,and good agreement was observed after comparing the two.In addition,this article discusses issues such as process coordination during construction,and analyzes the technical points that are different from conventional super high-rise steel structure projects during construction,such as spatial tower crowns and temporary tower crane attachments,which can provide a reference for the implementation of similar super high-rise steel structure in the future.
