HT_BIM: Parametric modelling for the assessment of risk in historic centers 7HT_BIM: La modellazione parametrica per l’analisi del rischio nei centri storici

The small historic centers are “environment monuments” to be safeguarded because of their vulnerability both from seismic and environmental point of view. The management of these urban realities is particularly complex due to the heterogeneity of data of individual building units, structural aggregates, and entire urban areas. Recently, BIM parametric systems have contributed enormously in the design, planning, construction, etc, of new buildings and also in cultural heritage management. The aim of this work is to develop the historical town information modeling system (HT_BIM), that is a specific BIM system for historical building aggregates that detects vulnerabilities both in structural aspects and in wind exposure and sunshine degradation phenomena.
