On the reading of the structural behavior of old masonry: The issue of the seismic assessment of archeological ruins

This paper addresses the problem of assessing the resistance of ancient Roman structures to normal lateral forces. This subject was examined by applying theoretical models, especially for historical masonry. Procedure Guidelines for the Assessment and Reduction of Seismic Risk of Cultural Heritage [1] were followed here. A lack of information exists within the models for seismic safety assessment. They are restricted to four main categories, which do not mention structures that lack integrity (FIGURE 1, a). Archeological findings, such as masonry elements, often lack integrity and suffer from instability of isolated parties under seismic actions. Nevertheless, a realistic assessment of their safety level is crucial for their survival, especially in regions prone to earthquakes. The attainment of the necessary safety targets is difficult to achieve without reinforcement. The practice of strengthening archeological assets avoids possible collapses. Contrarily, it is responsible for irreversible changes to t...
