The task of this work is the structural analysis and design of the reinforced concrete structure of the two-storey bistro building. The calculation was carried out manually, in accordance with engineering practise and Eurocode standards, and also using the SAP2000 computer programme. The calculation was carried out for slabs in the field and beams in the field and above the columns as well as for the ceiling and roof slab. Requirements were made for the gross area of the characteristic floor and the size of the cadastral plot, while other data were taken according to engineering practise. A manual calculation showed that the slabs of the ceiling structure that are only restrained on two sides require the most reinforcement. Slabs that are clamped on three or four sides require less reinforcement. As the slabs are load-bearing in two directions, most of the reinforcement is required in the direction of the shorter span of the slab. When calculating the beams, the largest amount of reinforcement is required above the columns and in the edge spans of the beams. In addition, beams located at the outer edge of the structure require significantly less reinforcement than those located in the centre of the floor plan of the structure. A computer model was created in the SAP2000 computer programme and used to calculate the reinforcement. When comparing the results from the manual calculation and the calculation in the SAP2000 programme, it was found that the computer programme requires more reinforcement for the design of beams and slabs in the field, while the transverse and longitudinal reinforcement for beams over columns is greater in the manual calculation. From this comparison it can be concluded that manual and computer calculations provide similar results for the internal forces, but significantly different amounts of reinforcement are required. The calculation in the computer programme is faster and also more detailed due to the many graphical representations of the structure, the internal forces and the reinforcement quantities
