Conjugate beam is also known as the imaginary beam that contains the similar dimensions (length) as that of the original beam but load at any point on the conjugate beam is equivalent with the bending moment at that point divided by EI.
. The conjugate beam method belongs to one of these geometric methods. Because the meaning of the term “Conjugate” is ‘related or reciprocal’, this method highlights substituting a real beam with an reciprocal imaginary beam for analysis.
