摘要
张拉整体网架结构是由离散的受压构件和连续的受拉构件组成的特殊结构体系.由于其轻质、网状、智能等特征,张拉整体网架结构一直成为国际研究热点.张拉整体网架结构作为新型大跨度空间结构,其研究正发展成为当今空间结构领域中最前沿的课题.寻找张拉整体网架结构稳定自平衡状态是研究这类结构的关键,是后续静力分析、动力分析和振动控制的基础,同时将影响这种新型结构体系在工程实际中的应用.主要叙述了张拉整体网架结构过去50年来找形的发展历程,总结归纳了各种找形方法的优缺点,并对后续研究做了展望.
Tensegrity grid structures are a special structural system composed of discontinuous compression member and continuous tension member. Characterized by lightness,reticulation and intelligence,the tensegrity grid structure has been an internationally-heated topic in the research filed. As a novel type of large-span space structure,the exploration of tensegrity grid structure is becoming the most advanced subject in the field of spatial structure. It is the key point for exploring tensegrity grid structures to search the steady self-balance status and it is the basis of following static analysis,dynamic analysis and vibration control,which will affect the application of novel structural system in the engineering practice. This paper mainly presents the development process of the form finding of tensegrity grid structure in the past fifty years,summarizes and concludes the advantage and disadvantage of different form finding methods,and makes a prospect of the future research.
