In the present thesis, two seismic retrofitting systems by Progetto Sisma S.R.L. from Modena, namely Sismagrid and Resisto 5.9 Tube, were examined. Both systems are installed on the exterior façade of the building. Sismagrid is composed of steel sheet strips, while Resisto 5.9 Tube represents a strengthening solution that combines seismic strengthening with improved energy efficiency and is designed as a steel frame system. Both systems are mounted on the existing façade using chemical anchors. Since these systems are not yet applied in Slovenia, this master’s thesis aimed to present them through presentation of laboratory test results, component descriptions, and installation procedures. To determine the effectiveness of the systems, pushover analyses were performed on an existing building in Grado, Italy, specifically at Hotel Montecarlo. Prior to the numerical analyses, in-situ inspections were conducted to determine some of mechanical and material properties of built structural elements. To illustrate the effects of these retrofitting systems, additional analyses were conducted using a system commonly applied in Slovenia, namely the FRCM system, specifically the SRG system by Kerakoll. A comparison of different strengthening systems was made considering additional load-bearing capacity, installation and material costs, as well as complexity of implementation of strengthening measures. For a better presentation of the building in both its existing and design states (with and without the Sismagrid and Resisto 5.9 Tube systems), structural models were developed using BIM tools in Autodesk Revit. Based on IFC models provided by Progetto Sisma S.R.L., the reinforcement elements could be modularly adapted and installed on the building façade.
