A new analysis method for bending problems of beam by the boundary element method has been developed. Main points of this study are (1) to improve the composition of the simultaneous equations by introducing a new formulation process, (2) to establish a scheme without any variables at intermediate points and (3) to establish a generalized solution scheme for an inhomogeneous beam. This report will describe (1) and (2). Size of matrix as well as the computing time are greatly reduced owing to these new algorithm, and therefore, high efficiency on the repetitive calculations is brought about. Using these algorism, it will become much more efficient to build an optimal design system by such as the genetic algorithm and so on.
