| Abstract: |
An additional floor is designed on the top of an existing RC building with frame structure. New transfer columns are supported on the existing beams of the top level. The frame is recalculated and design checks are carried out taking into account the construction stages. The corresponding conclusions about the redistribution of the internal forces depending on the type and the age of the structure are drawn. The necessary strengthening of the existing structure is considered, based on the results obtained by the calculations. Strengthening with FRP and RC jackets of the structural elements is considered as a final solution. |
