## 5 Conclusions  
The innovative connection detailing method, named Model IW-SB, proposed in this research was proved to be an effective and favorable solution in high seismicity areas. Under low seismic excitation, minor cracks could be observed in the infill panels and the frame members tended to behave in the expected mode according to the structural analysis. Under medium and high seismic excitation, the infill walls interacted with the bounding frame and provided structural redundancy to resist horizontal actions, and because of steel wire connections deployed in the mortar layers, satisfying in-plane stability and integrity of the infill panels could be achieved until the ultimate level of excitation. A general conclusion can be drawn that based on the comparative analysis between Model IW-SB and the referent Models 1 and 2, the Model IW-SB has better capacity for strength and deformation, especially for high seismic excitation. From the extensive experimental investigation performed in this study, it can be concluded that the proposed innovative connection detailing method can effectively mitigate undesirable damage to masonry infilled RC frame structures. The proposed technical solution consists of connection of the infill panel with bounding columns with steel wire connections, which are deployed in mortar layers and anchored to columns. The proposed simple connection is practical, cheap, and easy to implement without any specific technology, which is very important for developing countries in seismic regions such as N. Macedonia. Globally, the structural stability and integrity, the displacement ductility and the energy dissipation capacity of the masonry infilled RC frame are substantially improved. In view of the large number of masonry-infilled frame buildings in N. Macedonia and the Balkan region, the presented research is expected to provide useful guidance for seismic assessment and design of safer frame structures. Unlike traditional bed-joint or surface-mounted techniques, theIW-SB system offers a simplified internal anchorage approach that responds to observed stress demands while minimizing material and installation complexity. While the proposed method is primarily designed to offer a low-cost and easily implementable solution suitable for developing countries, it also has potential benefits in reducing overall construction costs in modern high-rise projects by serving as an effective alternative or complementary technique to more expensive methods, such as rubber bearings etc. Real-world applications would further support the practical relevance of the proposed method. While this study is primarily experimental, the reinforcement technique was developed in close collaboration with local construction practitioners, using readily available materials and tools. Future work will focus on field implementation and validation to further demonstrate the method's low cost and ease of use in practice. While the current study focuses on structural integrity and ultimate capacity under a single strong event, it is also important to test the method on potential impact on serviceability after multiple seismic events. It should be specifically noted that while some reduction in stiffness and minor cracking may occur, the proposed reinforcement aims to limit damage progression, suggesting a positive effect on maintaining serviceability. However, further cyclic or repeated loading tests would be beneficial to fully evaluate long-term performance in future studies. Even though the IW-SB method was primarily developed for new construction, it may also be adapted for retrofitting existing RC frame buildings. In such applications, particular attention must be given to the local stress concentrations introduced at the anchorage zones within the existing columns. A prior structural assessment is necessary to verify whether the column cross-sections and detailing are sufficient to accommodate the added forces, or whether local strengthening is needed before implementation.
