Nov 24, 2017 · Counterweight:A counterweight, typically used on lift bridges, draw bridges, or bascule bridges, is a weight that stabilizes and provides balance for the bridge lift system. Cutwater:A cutwater is a wedge-shaped component added onto a bridge pier.It is designed to resist water flow and break up ice, which helps reduce the pressure these elements place on a bridge. Bridges - SteelConstructionfoThe relatively low weight of structural steel components permits the erection of large sections; in some circumstances complete bridges can be moved into position overnight. Speed of steel bridge construction also benefits main contractors even on green field sites, as it allows them to establish and maintain access for haul roads.

The Effect of Bridge Design on Weight Bearing Capacity

Weigh each bridge before testing it so that you can calculate the bridge's strength-to-weight ratio after you break the bridge. Test how much weight each bridge can bear. Figure 10, shows you how to do this. Place the bridge to be tested between two supports (e.g., tables, workbenches, chairs, stacks of Use of High strength steel grades for economic bridge Higher steel grades (e.g. S690) are usually applied in steel members and/or in bridge regions with very high static stresses in order to reduce the cross sectional dimensions and plate thicknesses of these members. As a result the overall steel self-weight of the bridge will be
