Rammed earth is one of the oldest building materials in the world and is present in Portugal with a particular focus in the South of the country. The mechanical properties and the structural behavior of rammed earth constructions have been the subject of study of many researchers in the recent years. This study is part of a broader research on vernacular seismic culture in Portugal. Numerical analyzes were carried out to assess the influence of different retrofitting solutions in the behavior and seismic performance of an rammed earth building representative of the vernacular heritage of Alentejo region. Understating the structural fragilities of this type of constructions allowed determining the most appropriate retrofitting solutions.
