2nd Croatian Conference on Earthquake Engineering 2CroCEE

The historic building of “Sokolski dom” in Kumanovo belongs to the plain masonry type of buildings. Built in the thirties of the last century for the needs of the “Sokolski Society”, this building was once the main impetus for enrichment of cultural, entertainment and sports life, enabling the proper development of many generations. Due to its significance it was put under the protection as cultural-historic heritage in the country.
The subject of this paper is a detailed analysis of the stability of existing structure, which proved the need for its repair and seismic upgrading. With detailed analysis of the bearing and deformation capacity it was determined that the existing structure does not meet the requirements according to the national regulations. Therefore, the need for repair and strengthening was imposed, with the main goal of ensuring seismic stability of the building. Considering the possibilities and certain limitation for structural interventions from one hand, and the required bearing and deformation characteristics of the elements and the structure as whole from other hand, a traditional solution for strengthening was adopted, by reinforced concrete jackets and horizontal belt course. This technical solution provides increase of the structural bearing and deformation capacity of the system, as well as its ductility capacity, which is especially important for this type of buildings in case of seismic excitations. By increasing the deformation capacity, the input energy in the system would be consumed, which would greatly increase the seismic safety and security of the building.
