| Abstract: | By means of local inclined coordinate, a displacement field of parallel quadrilateral plate element is constructed by using parallel quadrilateral web finite strip of unit width, and the computing formulations of the element with 12 degrees of freedom are induced. The C 1 continuity condition is satisfied within the element and across the element boundary, being suitable for computing the large oblique plate structure. The computation examples indicate that the computing method is well reliable and high precise. |
