Hinges

The platform girders are pinned to the concrete rib and the frame girder. As there is no rigid connection, the girders cannot transfer any bending moments into the rib and frame.

Select the section no. 3 - IPE 200 in the navigator. All members featuring this section are highlighted in the graphics.
