The structural stiffness matrix can now be assembled using a dof. correspondence table, (ref. ยง9.10). Observation of the highest dof. number, i.e. 6, gives the order (size), of the structural stiffness matrix, i.e. 6 x 6. The structural governing equations and hence the required structural stiffness matrix are therefore given as
