Actually, the top side will buckle and the bottom side will snap. Dissipation Many beam bridges that you find on highway overpasses use concrete or steel beams to handle the load. … A single beam spanning any distance experiences compression and tension.The arch bridge can hold the most weight of the three, the deck truss bridge can hold an average amount of weight, and the beam bridge could hold the least amount of weight. This experiment tested the arch, deck truss, and beam bridges to see which could hold the heaviest amount of weight.

Dead load refers to the weight of the bridge itself. Like any other structure, a bridge has a tendency to collapse simply because of the gravitational forces acting on the materials of which the bridge is made.
Why do bridges have weight limits?
Bridges are typically posted with a weight restriction because a structural member(s) within the bridge has succumb to deterioration resulting in a reduction of that members structural capacity to carry the pre-design loads. In most instances, bridges are weight restricted for the deterioration of a bridge beam.
