Checking of connection of the flanges The connection of the flanges is a single lap joint. The flange component and the plate component will be verified. In general rule in the presence of a combination of loads, we obtain for each bolt a design shear force not parallel to the edge of the components. In this case, the Eurocode states that the bearing resistance can be verified separately for the bolt load components parallel and normal to the end of components.
