Abstract: Based on the urban safety theoretical framework of "Risk Source–Risk Exposure–Risk Mitigation", this paper systematically reviews key technological advances in the wind hazard safety research for rooftop building appurtenances, encompassing computational methods for rooftop wind fields, for detection and localization of rooftop appurtenances with damage identification, for the wind resistance performance of rooftop appurtenances, for debris motion mechanics and risk quantification, and for wind hazard resilience enhancement for rooftop appurtenances. The results indicate that the current rooftop wind field studies are predominantly based on single environmental factors and on stationary assumptions, making it difficult to capture the multi-physics coupling effects of wind–rain–debris under extreme wind hazards. The localization and damage identification of appurtenances under complex disaster and under environmental conditions lack robustness and generalizability. The debris trajectory simulations are mostly based on idealized conditions, with insufficient analysis of multi-scale impact mechanisms of debris transport pathways and, of collision risks on building clusters. The current wind-resistant design of appurtenances neglects building cluster interference and cascading debris effects, and generally fails to account for connection degradation and for performance deterioration resulting from long-term service exposure. To advance the field, the following key scientific challenges need to be addressed through further research: multi-physics coupled simulation methods for wind–rain–debris interactions, adaptive and intelligent recognition frameworks, high-fidelity debris flight dynamics models in complex urban building environments, and the layout optimization of rooftop appurtenances to enhance the wind resilience of rooftop building appurtenances.
