| Reciprocal frame has a time-honored history.With the development of construction technology and computing tools,the practice and application of the reciprocal frame in the building has been refocused.In addition,the unique construction form of the reciprocal frame is closely related to the structural logic.Therefore,it is necessary to analyze the technical level of the reciprocal frame deeply from the perspective of architectural design.Firstly,the historical evolution of the reciprocal frame was traced back.Taking the time axis as the line,the morphology evolution of the reciprocal frame was discussed in detail.Moreover,based on the classification criteria of materials,the work of pioneers of research and design in the related fields of the reciprocal frame was summarized,and the mechanism of morphology presentation hidden behind the reciprocal frame was explored.Then,the technical logic of spatial morphogenesis of the reciprocal frame from the surface to the space was expounded.From the perspective of geometric morphology,types of the reciprocal frame were discussed and sorted out in depth.Besides,under the concept of architectural space,the limitations and potentials of the application of the reciprocal frame were compared.Through case analysis,the morphology expansion strategies of the reciprocal frame were summarized.Lastly,the traditional rainbow-shaped bridge structure was rebuilded based on construction and structural logic.The relationship between the prototype and the rebuilding was discussed.According to the technical logic of combinatorial rebuilding and scale rebuilding,with the help of parametric softwares,the whole process of rebuilding rainbow-shaped bridge,from the morphological topology of reciprocal units to the architectural design morphology,was established.By introducing the new morphology of reciprocal units,the structural characteristics and structural logic of the reciprocal frame could be an effective strategy for the morphogenesis. |
