Considering the support ends (4) of the upper girder (2) as short consoles that are integral part of the soffit plate (1) it is obvious that the shortening of the soffit plate (1) pushes ends of the upper girder (2) towards each-other whereby the upper girder (2) bents upwards resisting in that way their common shortening. ***As a reaction***, ends of the upper girder (2) with major contribution part of the prestressing force push consoles (4), at ends of the soffit plate (1), rotating their ends and producing negative bending moments in the soffit plate (1) bending it upwards.
