1, structural prototype: observe the structural form produced by the combination of shape and force in nature. Such as soap bubbles formed by surface tension, spider webs hanging in the air and other flexible structures. And the rigid structure of shells, eggs and trunks. Compared with arch coupons, shell folded plates, suspended cable roofs, gas films, reticulated shells, beams, columns and frames in building structures. Similarity of honeycomb, snowflake and space grid structure related to building structure, such as space curved structures such as light bulbs, spoons, cups, helmets and airplanes; Composite tension structures such as spokes, wheels and badminton rackets of bicycles; The membrane structure displayed by the sail blown by the wind. These phenomena, which integrate structure, form and function, reflect people's actual needs, just like architectural structures.

2. Feature description: observe the appearance form, especially the shape features related to its structure, and generally describe the relationship between appearance and structure, as well as the relationship between usage and shape structure.

3. Force analysis: According to the force characteristics of the structural prototype, the force analysis is carried out with the knowledge of basic mechanics, structural mechanics and material mechanics. Distinguish between the structural part that plays a supporting role in the building and the non-structural part that is used for enclosure. Such as supporting beams and walls, and closing roofs and walls.

4. Structural space: taking the structural prototype as a reference, select similar structural systems from the building structure, such as truss system, frame system, cable system, thin shell system, etc. For a specific space, there are many possibilities to choose the structural system, and the structural system with a certain scale, convenient structural calculation and construction, and stable and reliable material characteristics is the most economical choice. After the structural system is determined, it should be optimized to determine the most effective geometric form of the structure. Reasonable structural selection is also one of the important conditions for creating architectural beauty.

5. Functional organization: according to the characteristics and requirements of the exhibition space, such as spatial adaptability, functional variability, expansion feasibility, etc.

6. Design expression: drawings, words and models.
