Repetition of triangle fountain of aldo rossi: Geometrical analogy of architecture

The study elucidated geometrical consistency among the architectures designed by Aldo Rossi (1931–1997), and showed the connection geometry and what he called “analogy”. In view of analogical connection, Rossi repeated ‘Triangle Fountain’, defined as geometrical compositions of triangular prism in his realized architecture. In order to define what caused analogy to connect his architectures, the study specified several “Triangle Fountain” in the entire of his architecture and simplified them to three types of geometrical diagram. One type was seen as “Lifted by Pillar” where the extruded triangular prism was lifted by supports. In the type, the triangular prism worked as bridge, where people or water go through inside. The second type was “Cantilevered”. In this type, one shorter triangular prism was on the wall, and water ran through from the wall and dropped into the cube drain. The third type is “Synthesized”, where Triangle Fountain was supported by pillar and wall. Despite several materials, Triangle Fountain gave consistency to his architecture. For the conclusion, geometrical analogy of the repetition of Triangle Fountains could be expressed as a geometrical formula, which showed the third type equaled to the first and second type. Like chemical formula of equilibrium, the repetition of geometry was rendered to another geometry enabled us to evoke another architecture in several sites.
