Abstract : The layout of steel piles is optimized to find the least weight structure. The pile cross-sections and the pile orientations (batters) are varied using optimality criteria. The handling of topological variables by the optimality criteria approach is thoroughly discussed. Several examples are given. One example is a retaining wall for which a two-dimensional pile layout can be used to represent a segment of the wall. Another example is a control tower. Four other examples are dam structures Anchorage, Steel piling, Piling, Structural optimization
