PRORAČUN ČELIČNE KONSTRUKCIJE VIŠEETAŽNE GRAĐEVNE

This master thesis presents the design of structural members of a multi-storey steel building to non-seismic and seismic effects. The structure is rectangular in plan, with dimensions of 48x35 m. The height of the building is 14.5 m, and it consists of 4 floors. The height of the ground floor is 4 m, while other floors are 3.5 m high. The building is to be used for office areas, located in Osijek, Croatia. The static system of the structure is such that lateral loads are resisted by bending of the columns and beams. The beams on which the secondary girders rest are IPE profiles, and the beams perpendicular to them are HEA profiles. HEA profiles were used for secondary girders. The columns are HEB profiles, with inner columns made as double (cross) HEB profiles, where one of them is cut in half-height and then welded on both sides of the other profile. The reinforced concrete slab is 15 cm thick and is defined as a horizontal diaphragm. Autodesk Robot Structural Analysis 2020 was used to model the structure. The thesis also includes the design of connections, modelled in IDEA StatiCa 10.1. Finally, structural drawings are presented, which include floor plans, cross-sections and characteristic details.
