A list of bracing heights (inches or mm) by group, between top and bottom connections. This is the distance between the centroids of the top and bottom chords used in the analysis. Bracing height for groups that are either specified as TYPE D BRACING, i.e. diaphragms, or defined by section properties with GROUPI and GROUPJ, is defined as 0.
