安联足球场（Allianz Arena）外墙，德国慕尼黑 »
安联球场 Allianz Arena 位于德国拜仁州首府慕尼黑的北部，安联体育场被选作 2006 年德国世界杯开幕式赛场。
Arena 球场半透明的外部膜结构幕墙可以改变颜色，现代化的膜结构技术构造了它精巧的结构壮丽的外观。
张拉膜结构分析设计软件
主体结构有限元分析计算
有限元结构分析软件 RFEM 是组成模块化软件系统的基础。主程序 RFEM 定义结构、材料、外力以及空间的板、墙和杆件结构。同时可以用程序创建混合结构以及处理体单元和接触单元。
膜结构找形
模块 RF‑FORM‑FINDING 可以对膜结构和索结构进行分析，形状由表面应力（给定的预应力和附加的外力，例如自重、压力等）与几何边界条件的平衡方程计算得出，分析得出的预变形模型将作为继续计算的基础。
膜结构裁剪
模块 RF‑CUTTING‑PATTERN 对膜结构进行剪裁分析设计。在弯曲几何尺寸上的剪裁边界条件是由边界线和独立的平面或者测地线确定。平滑处理是根据最小能量理论进行。

索膜结构找形分析和裁剪
This paper is focused on the specific aspects of designing membrane structures. These structures have specific requirements such as form-finding and cutting patterns generation. These topics are the focus of many research works and there are many methods proposed to achieve the desired results. However in this paper these issues will be discussed more from the practical point of view than from the theoretical one. The paper will be followed by examples, which will complement the discussed topic and show the special attention required during the design process.

在 RFEM 中找形
The RF-FORM-FINDING add-on module determines equilibrium shapes of membrane and cable elements in RFEM. In this calculation process, the program searches for such a geometric position in which the surface stress/prestress of membranes and cables is in equilibrium with natural and geometric boundary conditions. This process is called form-finding (hereinafter referred to as FF). The FF calculation can be activated in RFEM globally in the "General Data" of a model, "Options" tab. After selecting the corresponding option, a new load case or a calculation process called RF-FORM FINDING is created in RFEM. An additional FF parameter is available for defining surface stress and prestress when entering cables and membranes. By activating the FF option, the program always starts the form-finding process before the pure structural calculation of internal forces, deformation, eigenvalues, etc., and generates a corresponding prestressed model for further analysis.
