This paper introduces an efficient and refined special purpose finite element computer program, SUBWALL, for linear elastic structural analysis and design of complex reinforced concrete walls under arbitrary in-plane static loadings. An application of the substructuring technique as a means of reducing computer cost and increasing versatility in the use of finite elements for analyzing very large and complex structural walls is emphasized. Two detailed numerical examples are presented to illustrate the usefulness of the program in a design office.
