The RAM Manager is the gateway to the RAM Structural System Software. It contains commands that serve five main functions: creating, selecting and deleting databases, specifying design criteria, invoking the RAM Modeler for creation or revision of models, invoking the Analysis and Design modules, and invoking Post‑Processing commands. These functions are described in this chapter essentially in the order they appear in the RAM Manager menu. This is also, generally, the order followed when using the Structural System to analyze and/or design a structure: create a database, specify design criteria, generate a model, invoke the analysis and/or design modules, and obtain output.
