This work focuses on the design and assessment of the steel crane runways for two separated craneswith the capacity of 20 t, respectively 50/12.5 t. The main girder of the crane runway is designed as a welded uniaxially symmetric I-section consist a lattice horizontal reinforcing beam. The individual crane tracks are located within the building two-aisle production hall (one in each boat) with dimensions of 75 x 48 m and height of 14.9 meters. The building is located in an industrial area Holešov and its supporting structure is designed from crosslinks consisting of solid-welded columns and truss. Spatial rigidity of the hall is provided by tension bracings. The structures are made of the steel S 235. For designing of a production hall (for...
