This master's thesis deals with designing a steel hall in line with Eurocodes. The hall design involves the planning of the main load-bearing construction, a breakdown of loads, dimensioning and detailed construction drawing. Moreover, it determines continuous and changeable loads as well as seismic loads, all of which have been taken into account in the design process. Special attention was devoted to snow loads, specifically on the roofs bordering or close to taller buildings. The hall is designed in a way that causes exposure to snow loads. The dimensioning part was conducted using Scia Engineer software. Initial dimensioning included continuous purlins, which serve as real distribution of vertical loads. As for static loads, the dimensioning of the main steel construction was carried out on a spatial numerical model using nonlinear global analysis, while taking into account the second-order theory with imperfections. A modal response-spectrum analysis was conducted for seismic loads. The steel hall was designed as a construction with low energy dissipation. Internal forces were calculated using elastic global analysis, while the dimensioning portion corresponds to Eurocode 3 standards (without capacity design rules). Dimensioning of the selected joints is included in the final part of the master's thesis.
