%X Defects or violations in protection, maintenance, consolidation and restoration of Iranian historic buildings made of brick are as the indicators of performance failure in the preservation of valuable architectural heritage of Iran during structural interventions. The problem is considered as a factor for disintegration in the essential components of this building that is, incompatibility of physical form, concept, function, technology and integrity. Therefore, inefficiency of some damaging and unnecessary interventions will be significant in the rehabilitation process, lack of codified rules, lack of appropriate awareness and lack of efficient patterns in the seismic protection and rehabilitation plan of Iranian historic structures. The present study hunted to discover a pattern consistent with the seismic stability of buildings against earthquake risks specific to the Iranian plateau. For this purpose, the physical geometrical characteristics of sustainable historic buildings made of brick in earthquake-prone areas with average and high relative earthquake acceleration were studied. With the overall evaluation of quantitative and qualitative characteristics of Iranian historical standing buildings made of brick and determination of the origin seismic condition, physical dimensions in width, length, height and the calculation related to the geometric proportions i.e. relative levels relating to the ratio percentage of relative walls, the raw data of research are acquired. In evaluation of the technical engineering standards, Iran (2800) earthquake code, the world valid charters and cods such as; (FEMA, CHBC, ISCARSAH, ICOMOS, ICCOROM) have been considered. The reliability and validity of the data were assessed by (SPSS) software. Survey evaluation and analysis of quantitative data obtained from the measurements was done by factor analysis between the dimensional components of the building and correlation between effective factors. Path analysis, discovering interactive structure and structural equation modeling process (SEM) for seismic stability model was done through (AMOS) software. Explaining the structural equation modeling related to the final effective factor i.e. the important factor of potential for seismic failure as independent variable, vulnerable factor of direct seismic resistance as the dependent variable and mediating factor of indirect seismic resistance as intermediary, the fitness of direct and indirect relationships among these factors was assessed. The seismic stability model of Iranian historical brick heritage with perfect reliability and fitness were determined. This study can be a criterion for developing rules on assessment, seismic design, seismic retrofitting and structural interventions in Iranian monuments made of brick.
