索膜建筑的找形与工程设计

近１０年来，索膜建筑体系在我国有较快的发展，但在工程设计领域对此了解与认识相对滞后。“找形”是索膜结构设计的一个专用语，它的含意是在特定结构体系中，在已定的支撑边界条件下，通过结构计算分析确定膜面的形状，建筑师的参与是索膜建筑发展的首要条件。“找形”这一概念引入工程设计中，目的是向建筑师介绍索膜结构的几种基本体型，建筑师可以直接利用它，也可以用它的组合构筑符合功能和造型需要的体型。

THE FORM-FINDING AND DESIGN ARCHITECTURE OF TENSIONED CABLE AND MEMBRANE STRUCTURES

The system of tensioned cable and membrane structures was developing rapidly in the last ten years in China, but the knowledge and understanding fall behind in the engineering design field compared with that development. Form-finding is a professional term on the design of membrane structures. It means that in a specifical structure system. membrane shape is established by analysis and structure calculating according to. a given supporting borderline. The participation of architects is most important on the developing of membrane structures. Importing the conception of Form-finding, into engineering designs is to introduce several essential patterns of tensioned cable and membrane structures to architects, They may use those directly. or combine those into required shapes according to the function and sculpt of on architecture membrane design.
