Within the framework of this paper, the design of steel structure of the eight-storey building intended for a hotel is carried out, on the basis of Eurocodes. According to EN 1991-1-7, the building is classified to the upper risk group - CC2b and therefore additional requirements to the design has to be applied. The steel structure of the building should be checked in order to sustain an extent of localised failure from an unspecified cause without disproportionate collapse. It has been achieved by the three-part studies. In the first part, the frame structural members and the semi-rigid beam-to-column joints are verified for the normal design situation. The second part is related to the study of the structure subject to accidental damage due to a column loss. Three various accidental load cases are considered, in which the columns of the lowest storey are removed from three different positions. Finally, a design of the frame subject to the accidental situation has been performed using the key elements method based on the selection of the structural elements that are notified as the most critical and adoption of the recommended value of the accidental load, simulating an exceptional event within the accidental load combinations.
