UX indicates the displacement in the longitudinal direction of the bridge; UY indicates the displacement in the transverse direction of the bridge; UZ indicates the displacement in the vertical direction of the bridge; ROTX indicates the rotation around the X-axis; ROTY indicates the rotation around the Y-axis; ROTZ indicates the rotation around the Z-axis. The following is the same as here.
