摘　　要：凯博易控产业园研发办公楼为框架-剪力墙结构,由4个塔楼连接组合而成。各个塔楼的各楼层内存在标高变化,不同楼层之间存在层间连接。顶部2层采用大跨度空腹桁架作为悬挑梁支座。通过对包括方案选择、性能控制、计算分析在内的结构设计全过程的回顾,探讨了多重复杂高层结构设计的原则和要点。结果表明:在一定条件下,空腹桁架是兼顾结构性能和建筑需求的较优的结构形式;对于存在层间连接、层内高差的结构,层数、层高概念不同于常规,必须准确理解总体指标的含义,方能把握好结构总体性能;对于复杂结构,需对关键部位设定合适的抗震性能目标,全面考虑各种工况并应用多种方法,在整体结构、子结构、结构构件、构件节点等各个层次进行详细的计算分析,方能保证结构的安全性和适用性。The R&D office building in Kaibo Yikong Industrial Park is a frame-shearwall structure,which is composed of 4 towers linked and combined.There are elevation changes in each layer of different tower,and interlayer connections between different layers.Large-span vierendeel trusses are applied as supports of cantilever beams in the top 2 layers.By reviewing the whole process of structure design including scheme selection,performance control,calculation and analysis,the principles and key points of multi-complex high-rise structural design were discussed.The results shows that under certain conditions,the vierendeel truss is a good structural form that takes into account the structural performance and building needs.For the structure with interlayer connection and intralayer height difference,the concepts on the number of layers and the height of the layer is different from the conventional one,so that the meaning of the overall index must be accurately understood to grasp the overall performance of the structure.For complex structures,in order to ensure the safety and applicability of the structure,it is necessary to set appropriate seismic performance targets for key parts,comprehensively consider various working conditions and apply a variety of methods for detailed calculation and analysis at various levels including overall structure,sub-structure,structural components,component nodes.
