Abstract

A new diagrammatic procedure for reducing the bandwidth of a structural stiffness matrix is proposed. The minimum value of the bandwidth is one of the inherent properties of a structural configuration. It is sought without a node labeling procedure but through a redrawn configuration in a proposed coordinate system (with some restrictions) whose one axis corresponds to the size of the bandwidth. This strategy arises from the fact that the bandwidth reduction problem does not fit the characteristics of digital computers but neccessitates manual treatment in accordance with past experience in node labeling.
