Maremat & Me'mari-e Iran

The history and past of Iran's architecture is tied to various patterns and geometric motifs, as geometric motifs have been used to create decorative arrays of buildings and cities. Ahvaz city is one of the cities that has houses with decorative arrays in its old structure. These arrays at the entrance of the buildings and the internal and external walls of the buildings are often of the brick type, which act as the side shell of the building and are made of a variety of geometric motifs and changes in the pattern of the arrangement of bricks. The brick decorations of Ahvaz houses are valuable in terms of studies. The most important research questions are, "How many types are the geometric patterns of the brick decorations of Ahvaz houses divided into?" and "What is the frequency of each type of decoration, separately for internal and external walls?" Therefore, the purpose of this research is to identify the geometric patterns in the decorations of Ahvaz houses, and at the same time, the question raised in the research is answered. The research method is a combination of survey and historical-interpretive methods. The information has been collected through library and personal studies. The data test is based on Vicor's analytical method. The sample population consists of identified Qajar and Pahlavi period houses with brick decorations that are weighted by Shannon-entropy method, then the information obtained from the sample population survey was analyzed using statistical software and the Victor method. Finally, with logical analysis, it is concluded that the decorations of the Ahvaz houses, like their bodies, are in accordance with the climate and have visual and structural diversity. The decorative arrays of Ahvaz houses are more than beautiful, with diversity and functions such as air conditioning, easy passage for passers-by outside the house, spatial privacy in the house, creating more surface on the upper floors, creating shade on the walls and dissipating heat, preventing rain from falling on a part of the house. The facade of the building is to create variety of colors and variety of decoration and variety of form. It was also concluded that criteria such as geometric patterns, type of decoration, proportions, ratio of decoration to the wall, relationships and their arrangement can be used to measure decorations.
