explaining the methods of architecture representation using semiotic analysis (umberto eco’s theory of architecture codes)

In this paper, it is tried to explain the concept of representation and architectural representation through a qualitative methodology, approach its procedure for gradual creation in architecture and then according to scholars and to obtain the effect of this concept in the process of architectural facts the concepts are presented. in addition, it is referred to theories and practical texts by philosophers, and archaeologists and architects who have spoken about the architectural representation, and its definitions are also provided from the perspective of semiotics. then through a deductive view aiming to clarify the fundamental differences between types of architectural representation and according to the presented ideas, three fundamental roles in the representation of architecture as mimesis and imitation, architectural representation as abstraction and architectural representation as simulation are described and examples are cited for each of them. in the end, by a qualitative methodology and with an interpretive approach using the theory of umberto eco in architectural codes, the comparative tables are provided, and to clarify the relationship between the three methods of representation and the procedure of their ideas on the formation of the architectural reality are analyzed through the semiotic approach. finally, these comparative tables are separately classified in three groups of three so a variety of architectural representation techniques in diverse historical periods in architecture are explained as a result of this research.
