Abstract

The BUGA fibre pavilion built in April 2019 at the Bundesgartenschau in Heilbronn, Germany, is the most recent coreless fibre winding research pavilion developed from the collaboration between ICD/ITKE at the University of Stuttgart. The research goal is to create lightweight and high-performance lattice composite structures through robotic fabrication. The pavilion is composed of 60 carbon and glass fibre components, and is covered by a prestressed ethylene tetrafluoroethylene (ETFE) membrane. Each of the components is hollow in section and bone-like in shape. They are joined through steel connectors at the intersecting nodes where the membrane is also supported through steel poles. The components are fabricated by coreless filament winding (CFW), a technique where fibre filaments impregnated with resin are wound freely between two rotating scaffolds by a robotic arm. This novel structural system constitutes a challenge for the designer when proving and documenting the load-carrying capacity of the design. This paper outlines and elaborates on the core methods and workflows followed for the structural design, optimization and detailing of the BUGA fibre pavilion.

BUGA纤维馆的结构设计、优化和细节

BUGA纤维馆于2019年4月在德国海尔布隆的Bundesgartenschau建成，是斯图加特大学ICD/ITKE合作开发的最新无芯纤维缠绕研究馆。研究目标是通过机器人制造制造轻质高性能的晶格复合材料结构。展馆由60个碳和玻璃纤维组件组成，并由预应力乙烯四氟乙烯(ETFE)膜覆盖。每个部件都是中空的，形状像骨头。它们通过相交节点的钢连接器连接在一起，其中膜也通过钢杆支撑。这些组件是由无芯纤维缠绕(CFW)制造的，这种技术是通过机械臂将浸渍树脂的纤维丝自由缠绕在两个旋转支架之间。这种新颖的结构体系在证明和记录设计的承载能力时对设计师构成了挑战。本文概述并详细阐述了BUGA纤维馆结构设计、优化和细节设计的核心方法和工作流程。

期刊介绍： The aim of the journal is to provide an international forum for the interchange of information on all aspects of analysis, design and construction of space structures. The scope of the journal encompasses structures such as single-, double- and multi-layer grids, barrel vaults, domes, towers, folded plates, radar dishes, tensegrity structures, stressed skin assemblies, foldable structures, pneumatic systems and cable arrangements. No limitation on the type of material is imposed and the scope includes structures constructed in steel, aluminium, timber, concrete, plastics, paperboard and fabric.
