    Republic of North Macedonia is a seismic prone country with a long tradition and positive experience in the field of seismic design of new and strengthening of the existing buildings up to pre-defined levels of seismic protection. The principal seismic design philosophy which is stipulated in the regulations is based on protection of human lives against strong earthquakes and partially on controlled damage due to the so called frequent earthquakes. The current construction practice generally target only one of the seven basic work requirements for construction works defined in Construction Products Regulation (CPR, 2011) i.e. mechanical resistance and stability. Starting from 2013, when the first national regulation for energy performance of the building was issued, there are some positive initiatives/ examples at national and local scale. These initiatives encompassed building capacities in construction sector in order to provide competent and qualified national workforce, necessary for achievement of national energy efficiency targets; launching the energy efficiency programs for public buildings at municipality level (pilot-project), research experimental program for developing innovative technology for earthquake resistant and energy efficiency buildings, etc. However, till today there is no integrated methodology which will target simultaneously earthquake resistance and eco-efficiency of the existing building stock in the country.

    <jats:p>For the past few decades, during each disastrous earthquake, severe damage and poor seismic performance of masonry infilled RC frames, including many newly designed ones, have been reported extensively. Inherent problems related to analysis and design methods for tight-fit infilled frame structures have not yet been solved and are recognized as being far from satisfactory in terms of completeness and reliability. The primary objective of this research was to propose and test an innovative method that can effectively mitigate undesirable interaction damage to masonry infilled RC frame structures. This proposed technical solution consists of connection of the infill panel to the bounding columns with steel reinforcement connections deployed in mortar layers and anchored to the columns. This is practical, cheap and easy to implement without any specific technology, which is especially important for developing countries. A three story, two bay RC building model with the proposed connection implemented on the infill walls was designed and tested on the shake table at IZIIS in Skopje, N. Macedonia. The test results and design guidelines/recommendations from the proposed research are also expected to benefit the infrastructural development in other countries threatened by earthquakes, preferably in the Balkan and the Mediterranean region.</jats:p>
