The aim of this thesis is to design a load-bearing structure for the ultimate and serviceability limit state of a civil building. The structure is designed as a cast-in-place concrete structure, composed of columns and floor slabs. The building has total of 5 floors, two are under-ground and three above-ground. The thesis contents of a structural design and design options, structural design report for load-bearing elements, processing of the drawings, details, visualizations. Internal forces calculation is carried out in SCIA Engineer and validated by the moment accumulation method for slabs. The columns are assessed by interaction diagrams, one is verified by hand calculation. The resulting internal forces are taken from the computational programme. Foundations are not subject for solution.
