In many large structural analysis problems, due to the limitations in digital computer hardware, one is forced to partition the problem into smaller units to complete the analysis. When the partitioning is done by the analyst it is called substructuring. The paper is concerned with those partitionings that stem from the need of solving a large problem with a small computer. Considering only the displacement method of analysis, the important parameters of rational partitioning are displayed and the means of systematic partitioning are examined. Algorithms are given to improve present practice of partitioning from the standpoint of total computing cost.
