The stiffness matrix is derived for a finite element representing a beam column with rectangular cross section and a single edge crack. The element has zero length, and the standard nodal degrees of freedom associated with beam‐column elements. To illustrate its capabilities, the element is used to model propagation of multiple cracks in a self‐loaded fixed beam.
