Hierarchical data management for structural analysis

The use of formal data bases management systems is becoming increasingly necessary in computer programs for structural engineering. This paper briefly reviews data base requirements and the organization of integrated computer program networks and identifies a need for hierarchical data base management in computer programs for structural analysis. The nature of the data hierarchy is illustrated with reference to a building that has been analyzed by using substructure techniques. The organization and features of the hiearchical data base manager STRATA are then described. STRATA has been developed specifically for use in structural analysis.
