Preliminary analysis for the structural retrofitting of the Church of St. Stefano in Frassino.

The purpose of this thesis is to conduct a comprehensive structural evaluation of the Church of Santo Stefano. The research is conducted in accordance with the “Norme Techniche per le Costruzioni 2018”, Eurocodes, and Guidelines for Seismic Risk Assessment and Mitigation in Cultural Heritage. The theoretical framework of the study is primarily based on the aforementioned standards and guidelines. The research methodology begins with an extensive data collection process, including the examination of historical records, documentation of modifications over time, and analysis of past extreme events. Additionally, a thorough investigation of the structural materials is conducted, yielding valuable mechanical parameter data. Following the research phase, two calculation models are developed: a global model to comprehend the overall structural behavior, and a local model to analyze potential kinematic mechanisms. Advanced calculation software is employed to facilitate these modeling processes. The outcomes of the research provide a comprehensive understanding of the current structural condition of the church, highlighting areas that require intervention to ensure structural stability. The findings contribute to the preservation and conservation efforts of the church, assisting in the formulation of effective strategies for the safeguarding of this cultural heritage.
