Abstract: Macro-elements are one of the powerful means in reducing number of equations to be solved in finite element analysis. This is because a single macro-element will represent many finite elements. In this study a rectangular plate bending macro-element was developed. This macro-element is based on equivalent energy theory. The developed macro-element was tested and the results were compared with the results of the conventional plate bending finite element solutions. Excellent results were achieved with substantional reduction in number of equations required for the solutions. This reduction in number of equations will save computer storage and time especially for large structures.
