Deflection of single angles

If a single angle is continuously restrained the major geometric moment and major geometric section properties are used in the general equation governing the beam deflection.

Single angle deflections (continuously restrained, unrestrained)

However, because single angle geometric axes are not coincident with the principal axes; a different procedure is required if the angle is not continuously restrained, the procedure being as follows:

  1. External loads are transposed from the geometric axes to the principal axes.
  2. The deflection equations are used to calculate deflections in the principal axes.
  3. These principal axis deflections are then transposed to geometric axes again.
