| A semi-analytical Plate-beam super-element is developed in this paper.It is composed of plate-beam super-dement of bending and plate-beam super-eiement of plane stress,The mode shape functions for beams are used as the displacement functions of super-element of bending,the developed super-eiement has the merits of high accuracy and less degrees of freedom. It is a highly efficient super-element for the overall analysis,especially for dynamic analysis,of large complex structures with a great lot of plate and beam members.All the matrices of this super-element are derived herein. |
