| This paper presents a two-dimensional rectangular super element for analyzing the platetype truss structure. The structure,being partitional into many rectangular super element,being considered to sustain bending,shearing,tension and compression,extrusion andwarp,is analyzed with the FEM,it makes the problem to solving the complex built-up platestructure with many member system is changed into the two-dimensional problem,there-fore,the number of the unknowing varies is decreased,and the accuracy of the proposedmethod is well. |
