Aims The defect in the protection, conservation, maintenance, solidification, and restoration of historic brick buildings of Iran is a performance failure indicator in preserving the authenticity of Iranian architectural heritage in structural interventions. The aim of this study was to decode the seismic stability model of historic brick buildings of Iran.
Instruments & Methods The present descriptive research with survey method was conducted on the community of valuable and stable Iranian historic monuments; 36 cases were selected by judgmental non-random sampling method. A researcher-made questionnaire was used to determine the technical and engineering qualities of the buildings structures. Initially, a design model was developed and, then, modified with experimental data and path analysis aid. The data were analyzed by SPSS 19 software, using exploratory factor analysis and the varimax method in Kaiser standardization and AMOS 15 software with structural equation modeling (SEM) and absolute fit, adaptive fit, parsimonious fit, and regression.
Findings Three main high-value factors of 37.19%, 36.95%, and 22.07%, were found with the names of earthquake damage marvelous, affordability of direct seismicity, and indirect seismicity. There was a significant relationship between the destruction potentiality and tremor with the affordability of seismicity resistance of the monuments. Destruction and tremor potentiality had a significant effect on affordability and indirect resistance of seismicity. Conclusion The seismic stability model of historic brick buildings of Iran is confirmed, in such a way that with the proliferation of destruction potentiality or tremor, the seismic destruction of the buildings is intensified and with the development of direct resistance to earthquakes, the seismic stability of the buildings is intensified. Increasing indirect resistance and, in fact, the dimensional proportions factor, as an intervention, increases seismic stability of the buildings.
