The thesis deals with fabric structures, which are made of aluminium or steel frames covered with PVC membrane. First, we analyzed and according to the standard EN 1999-1-1 checked design of existing aluminum structures, which consist of specially designed extruded hollow sections. Such buildings are used for storage and sports facilities, they have low total mass and are very easy and quickly assembled. We analyzed structures of various spans and with different design loads and found out they are all optimally designed. In the next step we focused on a design of steel structures according to standard EN 1993-1-1 with the same technical characteristics as aluminium structures. Structures with different spans, grids, design snow loads and with a use of different strengths of structural steel were analyzed. To ensure smooth outer lines of the building use of rectangular and square hollow sections was dictated. Main goal of design was optimal consumption of material. In the last part of the thesis we dealt with concept and design of improved and optimized solutions for joints. Simple production and fast assembly had to be assured in order to get closer to competitive aluminium structures. We evaluated the results and came to the conclusion thatuduse of steel in industrial fabric buildings with larger spans is better and thus also more competitive than the aluminium.
