In addition to vertical loads, horizontal loads are transferred to the substructure/foundation at the fixed point.
In bridge construction, all horizontal forces, for example from wind, traffic, prestress, brakes, impact are introduced into the subsequent structures at the fixed point (1). In order to avoid constraints, the other supports (2) are designed as movable supports. Roller bearings are suitable for movable supports.

In the case of long, continuous bridges, the horizontal forces can also be distributed over several fixed points (3). In this way, you can reduce the maximum displacement distances on the movable supports.
