Tiivistelmä
This study intends to analyze possible constructive solutions applied when adding more floors to the existing buildings. The objective was to design the best applicable storey-adding structure, scenarios when strengthening scheme is adopted or not being considered. The work was commissioned by AlfaGasStroyServis LLC.
In the study, the emphasis is on the jacket type storey-adding technique when the portal frames on independent foundations are erected around the existing building. The frames joined together to form a structure that bears the load from the superstructure being built. Solutions with reinforced concrete, steel, and timber frame are discussed. In addition, the question of an effective floor system that can be used in the reconstruction is considered.
The estimates are based on existing scientific researches and developments. Calculations are carried out by means of special software using data obtained from the previous designs of the existing building.
As a result of this thesis, it is deduced that the load-bearing performance is weak to withstand the weight of additional structures. The extra storey in the form of a self-bearing system is designed. Materials are chosen considering their effectiveness and construction site conditions, cross-sections of the elements are selected.
