架构师提供的文本描述。位于澳大利亚墨尔本的Chadstone购物中心的扩建是对工程和建筑的无缝庆祝。该项目的核心是一个戏剧性的网格壳玻璃屋顶，它的腾空已经成为最大和最受欢迎的封闭购物中心在南半球。这一扩展可容纳100多家新零售商和一份休闲和食品经营者名册。这座31米高、7000平方米的屋顶是一个由设计师、建筑师和工程师与斯图加特大学和巴斯大学的研究部门合作的多学科合作项目。该设计团队依靠三维参数化建模，通过视频动画和计算机渲染相结合来细化集合。这是欧洲大陆上第一个这样的屋顶。

Text description provided by the architects. The expansion of Chadstone Shopping Centre in Melbourne, Australia, is a seamless celebration of engineering and architecture. The project’s centerpiece is a dramatic gridshell glass roof, which soars above what has become the largest and most popular enclosed shopping centre in the Southern Hemisphere. The expansion accommodates upwards of 100 new retailers and a roster of leisure and food operators. The 31-meter high, 7,000-square meter roof was a multi-disciplinary collaboration of designers, architects and engineers working with research departments from the University of Stuttgart and the University of Bath. The design team relied on 3D parametric modelling, refining the massing through a combination of video animation and computer rendering. The roof is the first of its kind on the continent.

产品说明。设计的突出特点无疑是Chadstone标志性的GridShell屋顶。它的结构是基于网格框架，该框架从其双重曲率导出其强度。由CallionRTKL、BuchanGroup和AtelierOne设计，位于伦敦，由德国和捷克共和国的塞莱制造，屋顶由具有不同尺寸的四边形面板的悬链线钢栅格壳组成。它的高度有效的形式只有210mm厚，覆盖大约7000平方米的面积，并且在一些区域允许高达42米的净跨度。

Product Description. The standout feature of the design is undoubtedly Chadstone’s iconic gridshell roof. Its structure is based on a lattice framework which derives its strength from its double curvature. Designed by CallisonRTKL, The Buchan Group, and Atelier One in London and manufactured by Seele in Germany and Czech Republic, the roof consists of a catenary steel gridshell glazed with quadrilateral panels of varying size. Its highly efficient form of only 210mm thick, covers an area of approximately 7000 square meters and in some areas allows clear spans of up to 42 meters. 

面板布局已被无缝映射到建筑周边，以提供一个优雅的边界之间的屋顶和支撑结构。与巴斯大学合作，我们开发了一个特定于项目的脚本，将二维点控制四边形网格转化为三维参数网格，将屋顶形状、玻璃面板和结构效率的关键相关方面结合起来。面板的尺寸受到限制，以确保没有制造或运输相关的限制，表面是在非常紧的平面极限发展，使小水平的冷弯曲在必要时不会产生明显的压力。

The panel layout has been seamlessly mapped to the building perimeter to provide an elegant boundary between the roof and supporting structure. Working in collaboration with the University of Bath we developed a project-specific script to translate a 2D point-controlled quadrilateral grid into a 3D parametric mesh, combining the critical interrelated aspects of the roof form, the glass panels and structural efficiency. The panel sizes were limited to ensure there were no manufacturing or transit-related restrictions, and the surface was developed within very tight planarity limits that enable small levels of cold bending where necessary without generating significant stress.
