The paper presents a numerical analysis of steel brackets supporting a double-span crane runway girders. The purpose of the study was to assess the new structural solution based on the stress distribution in the brackets. In order to simplify the connection, the bottom flange of the crane runway girder is based directly on the upper flange of the bracket. As a result, the support reaction is no longer applied in the plane of the bracket web, but it is carried as ununiform pressure. Known analytical methods are not sufficient to assess the level of the bracket material effort due to the mechanism of the forces transmission. That is why the FE analysis was performed. Twisting of the bracket caused by eccentric load (in addition to the biaxial bending) was observed. What is more it occurred that transverse stiffeners in the bracket structure generate high stress.
