In this paper, the concept of abnormal column is proposed, which can simply introduce the lateral displacement and influence matrix formulas of the complex girder with multiple height mutations. The characteristics of the static and dynamic analysis of the girder using this formula are as follows: When the stiffness coefficient is directly substituted into the formula, the sideshifts, internal forces, and influence matrices of the trusses are obtained, so it is simpler and easier to grasp than the existing methods. This paper provides a method to avoid tedious mathematical derivation and simply deduces the formula from the mechanical concept.
