某博士后站复杂混合结构设计研究

STUDY ON COMPLEX HYBRID STRUCTURE DESIGN OF A POST-DOCTORAL STATION

某集团博士后站建筑造型新颖,结构体系采用局部带钢支撑的复杂钢与混凝土混合结构。工程平面呈长条形,多处开大洞,各层存在较多超大悬挑梁,立面存在跃层斜柱,4层至屋顶有通高幕墙弧梁,结构存在较多不规则项,设计难度较大。本研究介绍了工程设计中的关键问题和处理措施,研究了长条形结构的扭转控制、二道防线调整、跃层斜柱、超大悬挑等关键问题以及设计方法,可为类似工程设计提供参考。

Novel structures are applied in the post-doctoral station,namely,complex steel-concrete hybrid structures with local steel supports.The project is in a long stripe shape with many large holes.Oversized cantilever beams are applied on different layers,cross-layer inclined columns on the façade,and full-height curtain walls and arc beams on the fourth layer to roof,with a number of irregular structures,leading to significant difficulties in construction.Key problems and solutions in engineering design are described.In particular,key problems and design methods are studied in terms of torsional control of strip structures,adjustment of two defense lines,cross-layer inclined columns,oversized cantilevers and the like,thus providing a reference for construction of similar projects.
