备注

针对运动结构日益广泛用于景观构筑物的现象,从影响运动结构稳定构形状态的基本构成单元切入,根据其自身的形变,将运动结构的单元归纳为可变形单元与不可变形单元两类,不同的单元类型对应不同的稳定构形. 研究表明,构成折叠结构的剪杆单元、刚性面板单元与索杆单元,构成充气膜结构的薄膜,构成开合结构的索膜均属于可变形单元; 界面开合、单元重组与整体移动则是基于不可变形单元实现的稳定构形转换. 稳定构形间的灵活切换适应了不同用途下的特定要求,在较短时间内实现了构筑物功能的改变与拓展.

In response to the phenomenon of widespread use of kinetic structures in landscape architecture, we set the key factors affecting stability of kinetic structures, namely the constructing elements. These elements can be categorized as either transformable or non-transformable ones based on their transformability. Each category corresponds to certain stable configuration. We find that the category of transformable elements includes foldable structures constructed from scissor-like element, rigid slab element and rod-cable element, inflatable structures constructed from membrane, and retractable structures constructed from cable-membrane. The transition to stable configuration is also based on non-transformable elements such as unfolding and folder planes, recombination of elements and entire movement of landscape architecture itself. The smooth transition between stable configurations can be tailored to match desired purposes. It will change and extend the functions of landscape architecture.
