heal.abstract	We present a combined or mixed method for the dynamic analysis of thin-walled structures, based on the superposition of beam and shell strains and displacements. Polynomial or exact shape functions are used for the interpolation of the shell displacements, while discrete degrees of freedom are introduced instead of the generalized von Karman coefficients. Special attention has been given to the integration schemes, because of the combined beam and shell behaviour of the considered structures. The stability and accuracy of the four-point integration scheme are studied by using the z-transform. The method is applied to thin-walled pipes and is also compared to the von Karman approach.	en
