During a comprehensive investigation and research phase in building repairing process following the 2020 Croatia Earthquakes, a significant number of originally embedded steel ties were found, not only in common masonry residential buildings, but in masonry arches and domes as well. Many of these ties were embedded in brick masonry, but also in stone masonry. The findings are graphically documented through overall disposition sketches, including anchoring and connection details, accompanied by photographs. During the assessment phase, numerical 3D models were used to analyze the influence of originally placed steel ties, revealing a significant impact on the behavior of arches and domes. So, the general comparative analysis is shown, illustrating basic differences in arches and domes behavior with and without ties. Additionally, several examples of embedded ties with conceptual variations and their influence on future structural interventions are discussed. In conclusion, strong recommendations are given about types and necessity of investigation procedures during the structural assessment phase.
