The algorithm capability was compared with that of others in the literature. A computer program has been developed to analyze reinforced concrete cantilever retaining walls using the IWDA algorithm. The results show that the IWDA algorithm is able to optimize retaining walls from viewpoints of cost and weight. The effect of the wall geometry has been investigated by considering four types of T-shape walls in order to discover the influence of contributing variables on objective functions. It has been found that backfill slope, unit weight and friction angle are important parameters affecting retaining wall cost and weight. Also, the Coulomb method in computing lateral earth pressure on retaining walls leads to lower cost and weight for retaining walls than the Rankine method. In general, optimizing retaining walls may lead to approximately 44 percent saving. Manuscript profile
