ADDMEM

Purpose: Used to add bracing in parallel/concentric geometry Girder System Projects. (Not applicable to Line Girder Projects.)

--> Given in girder system input

A list of values given in pairs of integers representing nodes between which additional braces are to be added. For example, "ADDMEM 21 42 36 18" adds braces between nodes 21 and 42 and between nodes 36 and 18. (Also see DELMEM and BRINCD).

If members are to be added as well as deleted, two layout executions are necessary if ADDMEM requires additional nodes (see ADN-i) because adding nodes will shift node labeling which may have been used for the DELMEM command. The procedure should be: (1) make a layout run involving only ADDMEM data, then (2) make an additional layout run involving both ADDMEM and DELMEM data, where node labels used for DELMEM were generated as a result of the first layout run.
