Abstract: In a multi-span bridge support system, the superstructure includes a row of elongated single-span girders arranged end-to-end and supported at their ends on vertical support columns. At least two adjacent girders in a row are provided with fixed bearings at the juxtaposed ends over a common support column. The opposite ends of the girders are mounted on horizontally movable bearings. The location of the fixed bearing and the common support column forms a fixed point. At the fixed point the ends of the girders are notched so that the vertical and horizontal surfaces within the notched region face corresponding surfaces on the top of the support column. A vertical bearing for transmitting horizontal forces extending in the elongated direction of the girders, is located between the top of the support column and the juxtaposed vertical surface within the notched region of the adjacent girders.
