Unreinforced masonry (URM) walls, widely used in low-rise and heritage buildings, are highly vulnerable to seismic events. Current evaluation guidelines for assessing the lateral strength of URM walls predominantly rely on empirical or semi-empirical methods derived from calibrated datasets. Consequently, a comparative analysis reliability these existing provisions is essential. In this study, comprehensive database 146 was compiled 26 research groups employed evaluate accuracy established guidelines, including ASCE 41-17, NZSEE, Eurocode 6, GB50003. The showed that 41-17 provided most accurate predictions with acceptable safety levels, while NZSEE produced more conservative estimates excelled predicting diagonal shear failure modes. 6 less results under high compressive stress, compared NZSEE. GB50003 model based Mohr-Coulomb theory lowest highest variability predictions.
