An HBIM-Based Protocol for Damage Classification and Severity Assessment Through Monitoring

Interpreting crack patterns and assessing their severity is essential for evaluating risk, planning interventions, and ultimately conserving historic buildings. Despite this importance, there is a notable lack of standardized protocols for classifying crack patterns, which need to be analyzed critically to effectively determine the most probable damage mechanism. Historic Building Information Modelling (HBIM) offers a valuable tool for visualizing and interpreting damage, as it facilitates the integration of crack data with other relevant factors, such as deformations, transformations and construction features. Furthermore, cracks and deformation can be spatially located within the model, allowing for a comprehensive understanding of damage. However, mapping cracks within HBIM remains challenging due to the absence of suitable tools and standardized methodologies. This paper proposes a damage analysis protocol that begins with the classification of crack patterns based on relevant features and guides the abstraction of the kinematics associated with these patterns. Additionally, the integration of monitoring data into the model allows for the assessment of damage progression over time and helps to validate the diagnostic hypotheses.
