The stiffness of shoulderbeams is important to maintain the integrity of columns. The requirements for
the stiffness of shoulderbeams to keep the stiff connection between the upper and the lower parts of
columns are studied, by simplifying the shoulderbeam as a spring hinge. And a method to compute the stiffness of shoulderbeams is put forward.
Keywords:  shoulderbeam; stiffness; polystyle column
