Bearing

This section defines the bearing construction stage.

Navigation: Construction > Substructure Construction > Bearing

Overview

The construction of bearings in a steel girder bridge is typically represented by two-node springs between the pier cap and the girder in a finite element analysis model. To prevent instability issues, it's usually recommended to incorporate the bearing construction stage into the girder construction stage. If the pier cap construction stage is used instead, the top node of the spring may not be connected to any elements, leading to unrestricted movement in non-fixed directions.
