La matriz es la misma que un elemento normal, en donde los factores de Inercia se transforman de acuerdo a los factores de las cartelas.
Revisa el Libro II de Biaggio Arbulu , sobre secciones variables, ahí están todas las ecuaciones para cada tipo de cartela (recta, parabólica, etc)
Saludos

Otra opción es discretizar los tramos acartelados en varios elementos de longitud e inercia correspondientes.
aunque es algo burda esta simplificación, suele servir para vigas de menor tamaño donde sobre dimensionar la cartela no supone un problema.
