Abstract

Cultural Heritage (CH) assets are a distinctive and valuable fragment of many areas worldwide, often representing a very important component of individual and collective identity. CH assets encompass not only individual buildings but also historic urban centres which are commonly formed by clusters of single units, undergoing to continuous transformations overt time. Although these additions tend to maintain the original shape, they very often modify the global structural behavior of the compounds. Furthermore, owing to their low-engineered construction features, CH assets are also perceived to be highly vulnerable to different natural hazards. To date, much research effort has been devoted to thoroughly understand the mechanism of damage that CH assets undergo in case of earthquakes. However, there is still a compelling need to develop quantitative methods able to assess the structural vulnerability of these buildings against different co-occurring perils, such as flooding or high wind speeds. Knowledge would be of great important to advance current mitigation measures for the retrofit of CH assets in multi-hazard prone countries, enhancing the decision-making process of their preservation to future generations. This paper presents a mechanic-based procedure for the collapse load evaluation of a specific category of CH assets, namely historical masonry structures (HMS), undergoing to earthquake, flood and wind. The procedure has been currently applied to a single wall, aiming to be extended to the whole façade element, considering variation in geometry, layout and material characteristics.
