Using modified strip distributed transfer function method, a strip element model with two nodal lines and four degrees of freedom is built for the analysis of static response. The rectangular region is divided into strips by nodal lines. The border lines are discrete. The displacements and angles of the inner lines and boundary nodes are unknown. An super element, which can couple with finite elements, is given using cubic interpolation. By using generalized function, an accurate integration method is developed to get the explicit formulation of the matrixes involved. This can improve the accuracy and efficiency of the method.
