摘要
大型扭曲结构是一种能较好地实现建筑美学与结构逻辑完美融合、协同创新的新型结构,具有将水平荷载转化为构件轴向力、充分发掘结构空间作用潜力的典型特征。首先,介绍了扭曲结构及其演变产生的过程,分析了其5个典型特征,指出了其不足,给出了其适应范围;其次,介绍了该类结构的组成,给出了基于不同特征的6种分类方法,为今后该类结构创新奠定了基础;最后,较为系统地收集、梳理和统计了国内外48栋高层或超高层扭曲结构的相关资料,给出了他们的直观图片,介绍了国内外采用扭曲结构的4栋典型工程案例,为全面认识、了解、推广应用扭曲结构提供了有益借鉴。
The large twisted structure is a new type of structure that perfectly integrates and collectively innovates architectural aesthetics and structural logic.It has the typical characteristics of transforming horizontal load into axial force of components and fully exploiting the potential of structural spatial effect.First,the article introduces the twisted structure and its evolution process,analyzes its 5 typical characteristics,points out its shortcomings,and gives its scope of adaptation.Secondly,the article introduces the composition of this type of structure,and gives six classification methods based on different characteristics,which lays the foundation for future innovation of this type of structure.Finally,the relevant data of 48 high-rise or super-high-rise twisted structures at home and abroad were collected,sorted and counted systematically,and gives their intuitive pictures,and introduces 4 typical engineering cases using twisted structures at home and abroad.It provides a useful reference for the comprehensive understanding,promotion and application of twisted structures.
