    This research aimed to strengthen heritage masonry buildings using fiber-reinforced paint (FRP) and evaluate seismic responses, including the Arias intensity scale, peak acceleration, peak displacement, lateral drift, and dissipated energy. In the numerical phase, the prototype model was studied using the Applied Element Method (AEM) and similitude law, resulting in a well-performing scaled model with error percentages of approximately 5 % for element results and 4 % for spring results. This validated the model's accuracy, leading to its adoption for experimental work. The experimental phase involved shake table testing of the scaled models, revealing that the unreinforced model (URM) collapsed at run 44, whereas the FRP-retrofitted specimen collapsed at run 52. Cracks in the FRP-retrofitted specimen began at run 39, compared to run 10 in the URM, with the FRP-retrofitted specimen arch masonry roof remaining undamaged prior to collapse. The FRP-retrofitted specimen demonstrated superior seismic performance, with an Arias intensity scale 3.67 times higher, base shear over 400 % greater, and lateral drift 10.89 times higher than the URM, indicating its ability to resist significant displacement and deform plastically. Additionally, the FRP-retrofitted specimen exhibited stable, wider hysteretic loops, leading to 6.1 times more energy dissipation than the URM, thereby offering enhanced safety for occupants.

    The authors regret that the affiliation of the fifth author (Wasim Khaliq) was wrong in the published article. The correct affiliation is “National Institute of Transportation, National University of Sciences and Technology (NUST), Islamabad, Pakistan.” The acknowledgement section should be updated by including the last line in the acknowledgement. The revised acknowledgement should read as: This project received the Fundamental Fund (FF) from Thailand Science Research and Innovation for the fiscal year 2024 (Contract No. 128/2567). Thanks are also extended to the Asian Institute of Technology (AIT) for supporting test facilities. The authors are also thankful to Dr. Yamamoto Kenjiro and Dr. Shanthanu Rajasekharan from Aster Co. Ltd., Japan., for support and guidance in executing this research. The authors would like to apologise for any inconvenience caused.
