A complete design of a steel structure frame of an industrial area with a crane system according to EN Eurocodes, which is a prevalent structure. Given the geometry, the technical specifications of cranes, and other analysis data, the structure will design step by step. First, load cases will specify and then they will assign to the analysis model elements appropriately. The design includes all possible, relevant crane positions. Then, load cases will combine appropriately, multiplied by load factors, producing Ultimate Limit State and Serviceability Limit State load combinations. Then comes the analysis of the structure model and the steel frame design, so that Ultimate Limit State and Serviceability Limit State criteria will be fulfilled. Frame sections will optimize, so that they will economically worthy. Last, some typical weld and bolt connections will calculate and they will show in detail drawings.

The aim of this thesis, is to present an analytical example for the design procedure of that type of structures or equivalent, according to EN Eurocodes.
