The conservation and assessment of masonry and historic structures represent a critical and multifaceted challenge in structural engineering, often requiring the support of advanced and reliable numerical modeling strategies [1]. This mini symposium aims to bring together researchers working at the forefront of computational modeling in the field of masonry and heritage structures. Contributions focused on recent advances in both continuum and block-based modeling approaches [2], as well as on innovative formulations for simulating the dynamic response and rocking behavior of masonry structures [3,4] are invited. Advances in practice-oriented modeling techniques, such as macro-element and equivalent frame models, are also welcome. In addition, the mini symposium will emphasize modeling strategies that tackle key challenges in historic structures including the effects of material degradation and environmental exposure, and the integration of numerical models with structural health monitoring systems. These modeling strategies may be applied to a wide range of built heritage, including buildings, infrastructure, and monuments. Computational approaches that support decision-making in historic structures conservation are strongly encouraged, also considering digital-twin and artificial intelligence (AI)-based tools.  REFERENCES [1] D’Altri, A.M., Sarhosis, V., Milani, G. et al.
