This paper presents an efficient calculation method which eliminates the LDU decomposition process of the stiffness matrix in numerical solutions of the finite element method (FEM). This method is applicable to an in-plane elastic analysis of plane bent and/or curved beams composed of variable cross sections. The FEM using this method decreases CPU time and memory capacity in comparison with the conventional FEM using the LDU process. In addition, this method makes the FEM algorithm simple, and gives more accurate results, Moreover, approximate elements are developed to extend the applicability of this method to beams and/or frame strucutures with various supported conditions. Therefore, this method is effective for microcomputer aided FEM.
