The aim of this study was to decode the seismic stability model of historic brick buildings of Iran.<br> 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.<br> 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. <span>اﻫﺪاف: وﺟﻮد ﻧﻘﺺ در ﺗﺎﻣﻴﻦ اﻫﺪاف ﺣﻔﺎﻇﺖ، ﻧﮕﻬﺪاری، اﺳﺘﺤﮑﺎمﺑﺨﺸﯽ و ﻣﺮﻣﺖ ﺑﻨﺎﻫﺎی ﺗﺎرﻳﺨﯽ آﺟﺮی اﻳﺮان، ﺷﺎﺧﺺ ﻧﺎرﺳﺎﻳﯽ ﻋﻤﻠﮑﺮد در ﺣﻔﻆ اﺻﺎﻟﺖ ﻣﻴﺮاث ارزﺷﻤﻨﺪ ﻣﻌﻤﺎری اﻳﺮان ﻃﯽ ﻣﺪاﺧﻼت ﺳﺎزهای اﺳﺖ. ﻫﺪف ایﻦ ﭘﮋوﻫﺶ، رﻣﺰﮔﺸﺎﻳﯽ از ﻣﺪل ﭘﺎﻳﺪاری ﻟﺮزهای ﺑﻨﺎﻫﺎی ﺗﺎرﻳﺨﯽ آﺟﺮی اﻳﺮان ﺑﻮد.<br> ﻣﻮاد و روشﻫﺎ: ﭘﮋوﻫﺶ ﭘﯿﻤﺎیﺸﯽ و ﺗﻮﺻﯿﻔﯽ ﺣﺎﺿﺮ روی ﺟﺎﻣﻌﻪ ﺑﻨﺎﻫﺎی ﺗﺎریﺨﯽ ﭘﺎیﺪار ارزﺷﻤﻨﺪ ایﺮاﻧﯽ اﺟﺮا ﺷﺪ. ﺗﻌﺪاد ۳۶ ﺑﻨﺎ ﺑﺎ روش ﻧﻤﻮﻧﻪﮔﯿﺮی ﻏﯿﺮﺗﺼﺎدﻓﯽ ﻗﻀﺎوﺗﯽ اﻧﺘﺨﺎب ﺷﺪ. از ﭘﺮﺳﺶﻧﺎﻣﻪ ﻣﺤﻘﻖﺳﺎﺧﺘﻪ ﺑﺮای ﺗﻌﯿﯿﻦ ﺧﺼﻮﺻﯿﺎت ﻓﻨﯽ و ﻣﻬﻨﺪﺳﯽ ﮐﺎﻟﺒﺪ ﺑﻨﺎﻫﺎ اﺳﺘﻔﺎده ﺷﺪ. اﺑﺘﺪا یﮏ ﻣﺪل اوﻟﯿﻪ ﻃﺮاﺣﯽ و ﺳﭙﺲ ﺑﺎ دادهﻫﺎی ﺗﺠﺮﺑﯽ و ﮐﻤﮏ ﺗﺤﻠﯿﻞ ﻣﺴﯿﺮ اﺻﻼح ﺷﺪ. دادهﻫﺎ ﺑﺎ ﻧﺮماﻓﺰار SPSS ۱۹ از ﻃﺮیﻖ آزﻣﻮن ﺗﺤﻠﯿﻞ ﻋﺎﻣﻞ اﮐﺘﺸﺎﻓﯽ و روش واریﻤﺎﮐﺲ در اﺳﺘﺎﻧﺪاردﺳﺎزی ﮐﺎیﺰر و ﻧﺮماﻓﺰار AMOS ۱۵ ﺑﺎ ﻣﺪل ﻣﻌﺎدﻻت ﺳﺎﺧﺘﺎری (SEM) و اﻧﺠﺎم ﺑﺮازشﻫﺎی ﻣﻄﻠﻖ، ﺑﺮازش ﺗﻄﺒﯿﻘﯽ، ﺑﺮازش ﻣﻘﺘﺼﺪ و رﮔﺮﺳﯿﻮن ﺗﺤﻠﯿﻞ ﺷﺪﻧﺪ.<br> یﺎﻓﺘﻪﻫﺎ: ﺳﻪ ﻋﺎﻣﻞ اﺻﻠﯽ ﺑﺎ ارزش ویﮋه ﺑﺎﻻ ﺑﻪﺗﺮﺗﯿﺐ ۳۷/۱۹%، ۳۶/۹۵% و ۲۲/۰۷% ﺑﺎ ﻧﺎمﻫﺎی ﺧﺮاﺑﯽ ﻟﺮزه اﻧﮕﯿﺰی، اﺳﺘﻄﺎﻋﺖ ﻟﺮزه ﭘﺬیﺮی ﻣﺴﺘﻘﯿﻢ و ﻟﺮزهﭘﺬیﺮی ﻏﯿﺮﻣﺴﺘﻘﯿﻢ ﮐﺸﻒ ﺷﺪﻧﺪ. ارﺗﺒﺎط ﻣﻌﻨﯽ داری ﻣﯿﺎن اﺳﺘﻌﺪاد ﺧﺮاﺑﯽ و ﻟﺮزهاﻧﮕﯿﺰی ﺑﺎ اﺳﺘﻄﺎﻋﺖ و ﻣﻘﺎوﻣﺖ ﻟﺮزهﭘﺬیﺮی ﺑﻨﺎﻫﺎی ﺗﺎریﺨﯽ وﺟﻮد داﺷﺖ. ﻋﺎﻣﻞ ﺧﺮاﺑﯽ و اﺳﺘﻌﺪاد ﻟﺮزه اﻧﮕﯿﺰی ﺑﺮ ﻋﺎﻣﻞ اﺳﺘﻄﺎﻋﺖ و ﻣﻘﺎوﻣﺖ ﻏﯿﺮﻣﺴﺘﻘﯿﻢ ﻟﺮزهﭘﺬیﺮی ﺗﺎﺛﯿﺮ ﻣﻌﻨﯽداری داﺷﺖ.<br> ﻧﺘﯿﺠﻪﮔﯿﺮی: ﻣﺪل ﭘﺎﻳﺪاری ﻟﺮزهای ﺑﻨﺎﻫﺎی ﺗﺎرﻳﺨﯽ آﺟﺮی اﻳﺮان ﺗﺎیﯿﺪ ﻣﯽﺷﻮد، ﺑﺪیﻦ ﺻﻮرت ﮐﻪ ﺑﺎ ازدیﺎد اﺳﺘﻌﺪاد ﺧﺮاﺑﯽ یﺎ ﻟﺮزهاﻧﮕﯿﺰ، ﺧﺮاﺑﯽ ﻟﺮزه ای ﺑﻨﺎﻫﺎ ﺷﺪت ﻣﯽیﺎﺑﺪ و ﺑﺎ ﺗﻮﺳﻌﻪ ﻣﻘﺪار ﻣﻘﺎوﻣﺖ ﻣﺴﺘﻘﯿﻢ در ﺑﺮاﺑﺮ زﻟﺰﻟﻪ، ﭘﺎیﺪاری ﻟﺮزه ای ﺑﻨﺎﻫﺎ اﻓﺰایﺶ ﻣﯽ یﺎﺑﺪ. اﻓﺰایﺶ ﻣﻘﺎوﻣﺖ ﻏﯿﺮﻣﺴﺘﻘﯿﻢ و در واﻗﻊ ﻋﺎﻣﻞ ﺗﻨﺎﺳﺒﺎت اﺑﻌﺎدی ﻧﯿﺰ ﺑﻪﺻﻮرت ﻣﯿﺎﻧﺠﯽ، ﭘﺎیﺪاری ﻟﺮزهای ﺑﻨﺎﻫﺎ را اﻓﺰایﺶ ﻣﯽدﻫﺪ. </span> https://bsnt.modares.ac.ir/article_821_4558dbb6f6f8bb2e16d03b85bde76e2c.pdf
