Purpose: Used to specify bracing section properties in Girder System Projects. (Not applicable to Line Girder Projects.)
--> Given in bracing input
A list of flexural moments of inertia (in4 or mm4) by group (see GRP-i) as an alternative to giving bracing types and shapes. Zero values for any groups indicate types and shapes are specified for such groups and flexural stiffness determined for those groups. (Also see GROUPJ , GROUPWT)
For example, GROUPI 0 2094 0 indicates the shapes and bracing type are given for groups 1 and 3, but a flexural moment of inertia of 2094 is to be used for group 2.
