The graduation thesis examines the analysis and design of a reinforced concrete slab. Slab loads are based on guidelines from standards SIST EN 1990 and SIST EN 1991-1-1, and the design is made according to standard SIST EN 1992-1-1, which covers concrete structures' design. The slab is analysed with finite element method using Safe computer code. The process of modeling slab structure in Safe computer code is described. Based on loads from ultimate limit state reinforcement is calculated and shear resistence of concrete cross-section is checked. It is also proven that deflections and crack widths due to loads from service limit state are with maximum limit values. eflections are
calculated with respect to concrete creep and shrinkage.
