Alphen aan den Rijn Municipality – FietsappelAlphen aan den Rijn 市政府 – Fietsappel

A unique bicycle parking facility in the shape of an apple, large enough for 1000 bicycles, aptly named the ‘Fietsappel’ now takes centre stage at the new station boulevard in Alphen aan den Rein, the Netherlands. Two parallel upward spiralling curves constitute the basic geometry of the structure. The structure consists of a triangulated space frame shell (‘apple peel’), 9 CHS columns with spiral beams (‘apple core’) and bearing mounted stalk with a cable staying suspension system (‘apple stalk’ and ‘apple leaf’). By implementing XML scripts coding with FE technique, a parametric model is built which saves lots of modelling time. Various challenging detail engineering is required to resolve the complicated spatial geometry.一座苹果造型、可容纳 1000 辆自行车的独特停车设施——恰如其名的 “Fietsappel”（自行车苹果）——如今矗立在荷兰 Alphen aan den Rijn 新车站林荫道的中心。结构的基本几何由两条平行向上的螺旋曲线构成：三角化空间网壳（“苹果皮”）、9 根带螺旋梁的圆管柱（“苹果核”）以及支座安装、带斜拉索悬挂系统的果柄（“苹果柄”与“苹果叶”）。通过 XML 脚本结合有限元技术建立参数化模型，大幅节省建模时间。复杂的空间几何需要多项具有挑战性的细部工程来解决。
