Many of the stone monuments in the Angkor archaeological site, a UNESCO World Heritage Site, are currently ruins. The condition of the intact monuments is worsening quickly.

Thus, international experts are looking intensively into the causes of the poor technical condition of these important monuments and trying to find suitable solutions to rescue them. The Czech research team is participating in saving these monuments in Angkor as well, with the five‑year research project "Thermal Imaging and Structural Analysis of Sandstone Monuments in Angkor".

The main objective of the project is represented by an analysis of the stone structures' loading due to environmental temperature changes and the influence of this loading on the static safety of the monuments. In addition to the research work on-site in Angkor, the project includes numerical simulations of the structural behavior of the stone structures, which are mainly subjected to temperature effects.

The structural engineering software RFEM for FEM analysis and design by Dlubal Software was used to create numerical models and carry out the structural analysis.
