Comparative structural analysis of public buildings in the three periods of the first Pahlavi, the second Pahlavi and after the revolution in Tehran

One of the most important factors in defining the scope of discipline in the field of Iranian architectural stylistics is comparative research of different time periods based on the study of the causes of various approaches and trends and their impact on the cognitive construction of architecture. For this purpose, the present study, with an analytical-historical method, has comparatively studied the cognitive structure of government buildings in the three periods of the first Pahlavi, the second Pahlavi and after the revolution. Because such buildings have a significant role in promoting different architectural styles due to the full support of the government. Since the coup d'etat of 1299 AD, the whole country came under the domination of the capital and government and public activities and buildings were first concentrated and built in the capital, the city of Tehran has been selected as the study area. In this regard, it was tried to measure the relationship between thought and action by extracting the structural components as subsets of the characteristics of different periods, ie the degree of adaptation of the works with the common theories of their period. Scope of the discipline It is possible to obtain study strategies to formulate theoretical foundations for support in the future.
