Fixed Point

Glossary Term

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