The article delves into the seismic vulnerability analysis of a Pombalino style building situated in Lisbon, recognized as a heritage site of Municipal interest. The structure, showcasing typical post-1755 earthquake construction features, underwent a detailed assessment using non-linear analysis methods. By employing the 3Muri software for structural modeling and calibration with in-situ dynamic tests, the study revealed the building’s seismic weaknesses and behavior. The research emphasizes the significance of advanced analytical techniques and understanding the unique historical context of the building to accurately evaluate its seismic performance.
Furthermore, the study scrutinized the structural characteristics of the Pombalino building, transitioning to Gaioleiro style at some point, to identify potential vulnerabilities. The analysis highlighted the necessity for structural reinforcement due to the structure’s failure to meet EC8 criteria based on the N2 method. The research underscores the importance of considering local collapse mechanisms and ensuring adequate safety checks for both global and local structural assessments.
In conclusion, the study sheds light on the challenges and solutions in assessing the seismic vulnerability of historic masonry buildings, particularly those with unique architectural and structural features. By integrating advanced analytical methods and historical context, the research provides valuable insights into enhancing the seismic safety of existing structures, emphasizing the need for meticulous analysis and reinforcement strategies to ensure structural integrity and safety in seismic events.
