Architecture is one of the branches of art and civilization, which has long been the focus of people in different eras. Since historical buildings have been damaged for many years, they need to be consolidated with appropriate methods. So, various methods have been used for the stability of these buildings since long ago. But nowadays minimizing the amount of damage to the building during the restoration of the historical building is crucial. Therefore, the purpose of this research is to analyze the methods of strengthening brick buildings based on international charters and conventional methods of strengthening in the world. So, this research was done in order to answer questions such as "which of these methods is more suitable for the restoration of unreinforced brick buildings? " and "which technique is more compatible with the materials of masonry structures? ". This article is based on survey-descriptive method along with statistical analysis by SPSS software. Also, this study uses library sources to gather data to investigate new and old consolidation methods. In this regard, first, a questionnaire consisting of traditional and common strengthening methods, including the use of wooden piles, the use of micropiles, the implementation of gunite and shotcrete methods with today's modern techniques, as well as using all kinds of geosynthetics, composites and polymer meshes were prepared with different mortars; Then, with the aim of determining the degree of compliance of each method with criteria such as the level of need for expert staff, the degree of coordination in color and texture, reversibility and the minimum amount of intervention, it was provided to experts in the field of restoration. Finally, the findings of the research showed that the traditional methods, such as the implementation of backbands and wooden piles, are more compatible with masonry structures due to the harmony of the materials and often due to the high reversibility. Moreover, traditional methods are not able to guarantee the stability of the building over time, so, modern methods such as geogrids and the use of modern mesh mortars can be a suitable replacement for these methods.
