        1 - The analysis of the spatial structure of Qom metropolis with emphasis on the formation of sub-cores

        Among the patterns of building a city, a , polycentric cities pattern of larger cities is true, as experience has shown that smaller cities, especially historic cities, often have a metropolitan core, usually located in the central geometric and historical boundaries of the city. This is due to the physical development of large cities towards the periphery, urban sub-centers, and the city’s multi-core spatial structure gradually emerges. The present paper aims to identify the evolution of the spatial structure of the metropolis of Qom from the viewpoint of the nuclei and urban centers, especially in the last three decades. The idea of this research was that the specific characteristics and functions of the city prevented the city from becoming a part of the city’s central depopulation, as compared to other similar cities. For analyzing data, quantitative methods including general G and LISA statistics, standard deviation and kernel density functions have been used in Arc Gis 10.3 software. The results of the research show that the metropolis of Qom despite its special religious features and its second rank in the religious cities of the country after the holy Mashhad, like many other major Iranian-Islamic cities, have been shown to accelerate urbanization and the physical and diffuse development of urban texture during the year. From 1986 to 2016. During this process, the central part of the city still retains many of its functions, and despite the relative burnout and physical barriers and constraints, it is now considered to be the most important urban core in the metropolis’s spatial structure. Consequently, the metropolis of Qom is rapidly increasing due to the rapid increase in population and extent (horizontal expansion), as well as the formation of some urban centers, nodes and sub-centers, although it is changing to several cities, but because of specific religious features and Its extensive functions in the central part of the city are still known as a Single-core city dominated by the city’s historical core.

        2 - The physical-spatial structure analysis of the social classes houses in Oil company town “Abadan” during the boom of the oil industry, with the method of space syntax

        The large consumption of oil for energy has had important implications for urban development and globalization in the twentieth century. One of them was the creation of a company town and, consequently, new physical and spatial forms of housing in them. Much of this has been done by British government, in the exploitation of oil and, consequently, the creation of the Oil Company town. Separated social classes based on social status and the special architecture associated with it are prominent features of the Oil Company town. The aim of this study was to investigate and identify the physical-spatial structure of the allocated spaces to each social class and compare changes in these existing social structures in “Abadan”, Is done by space syntax method.we used the qualitative, descriptive-analytical research method, and finally the logical reasoning based on statistical and quantitative data. Depth map software, in items such as depth, integeration, connectivity,control and distribution, have been used in the selected plans of each class. The results and findings comparatively show the adaptation of the social structure to the architecture structure. In these structures, from the working class to the lesser masters, the structure has moved towards extroversion and fundamental change with its traditional form, and the separation and classification of spaces and the creation of spatial hierarchy, as well as individualism and privacy, in the working class to the bosses, according to the data. Software and analytics have increased step by step, and as of today, existing homes are getting closer. Manuscript profile

        The spatial structure of quarters plays a fundamental role in revitalizing and improving their quality. Emphasizing the reconstruction of cultural heritage, this approach can serve as a suitable catalyst for strengthening related issues or the spatial structure of historical quarters. This research aims to reconstruct the spatial structure of the Arg quarter in Mashhad. The methodology employed is mixed (quantitative and qualitative), where initially, by defining the criteria for cultural reconstruction in both soft and hard environments and categorizing them into seven dimensions of the urban environment, the cultural criteria in the components of spatial structure were elucidated. In the second step, quarter issues in the Arg quarter were extracted through the perspectives of authors, experts, and residents using observation and interviews, then the issue network was drawn and analyzed using qualitative research analysis tools (Gephi software). The results of the research indicate that the most important issues of the spatial structure of the Arg quarter include the lack of day and night activities, neglect of social values, functional disturbances in space and activities, inappropriate environmental qualities, and the loss of a sense of place, which can be addressed by proposing suggestions for improvement based on the identified issues.
