-
In the conjugate beam method, the bending moment diagram of the real beam is treated as the load on the conjugate beam.
-
The support conditions in the conjugate beam change according to the boundary conditions of the real beam:
-
A fixed support in the real beam becomes a hinged support in the conjugate beam.
-
This is because a fixed end in the real beam (zero displacement and rotation) corresponds to a point in the conjugate beam where the slope is zero but rotation is allowed, like a hinge.
-
-
This transformation helps analyze beam deflections and rotations using simpler static analysis of the conjugate beam.
