2D Global-to-Member Coordinate Teaching View

This planar example isolates the rotation of vector components into a member-aligned x′–y′ system. STAAD frame members are three-dimensional and also have a local z direction and cross-section orientation.

2D component transformation

[x′y′]=[cos⁡θsin⁡θ−sin⁡θcos⁡θ][XY]\begin{bmatrix} x' \\ y' \end{bmatrix} = \begin{bmatrix} \cos \theta & \sin \theta \\ -\sin \theta & \cos \theta \end{bmatrix} \begin{bmatrix} X \\ Y \end{bmatrix}
X,YX,Y = global vector components
x′,y′x',y' = components resolved in the rotated member-aligned planar basis

Global X-Y: fixed axes for this planar teaching model.

Member-aligned x′-y′: a rotated component basis, with x′ following the member centerline. For a real 3D STAAD member, confirm local y/z and beta orientation as well.
