In this paper, we present a new quadrilateral discrete Kirchhoff flat shell element (called DKQ16) with sixteen degrees of freedom (three displacements U, V, W at each corner, a rotation theta, at each mid-side) for the linear analysis of plates and shells. This new element is formulated on the basis of the so-called rational element method proposed by W. Zhong et al. In this new formulation, the rational quadrilateral plane element (RQ4) is employed for the membrane part and a new discrete Kirchhoff plate element DKQ8 proposed by the present authors is taken for the bending part. The DKQ 16 element is one of the most simple quadrilateral flat shell elements. It can be combined with the DKT 12 (or Morley) element. Numerical results for some typical problems demonstrate the overall good performance of the new shell element.
