What does "fixation" mean in steel structures?
In general, the rigid connections of steel structural members can be completed by welding, riveting and high-strength bolts.
The solid connection is the rigid connection, which completely limits the relative displacement and the rotation angle of the two members at that point. The rigid joint can transfer the axial force, the lateral force and the bending moment to each other.
It is one of the connecting patterns between two components.
