The project focuses on investigating the seismic vulnerability and risk of rammed earth houses, particularly those characteristic of Eastern Croatia. These houses represent a valuable part of Croatia’s cultural heritage but are often at high risk of damage or collapse during earthquakes due to the lack of seismic regulations and engineering data on their structural properties. The project combines experimental testing and numerical modeling to improve the understanding of the seismic behavior of rammed earth walls and houses. The experimental campaign includes destructive testing of full-scale physical house models on a shake table at the Žrnovnica laboratory – the first such research in Croatia. The data generated from these experiments are used to validate advanced nonlinear numerical models that simulate structural behavior under various seismic scenarios. The project also involves behavior factor analysis, seismic fragility assessment, and earthquake risk quantification through the development and application of methods such as multivariate statistics and parametric analysis. The ultimate goal is to propose guidelines for earthquake-resistant design and the preservation of traditional earthen houses, contributing to the advancement of both European and national construction standards. The project is part of the broader RE-forMS research program, ensuring continuity of research beyond the completion of the core project while simultaneously supporting the education and training of a new doctoral researcher.
