BBDL

 

Purpose:  Used to indicate bays where bracing is unbolted for noncomposite dead load.

 

-->    Given in girder system input

 

Followed by a list of zeros and ones to indicate which bracing bays are selectively unbolted for construction loading.  Only intermediate bracing in those bays can be unbolted.  For example, BBDL  1 1 0 1 1 would be used if intermediate bracing in the third bay was unbolted for noncomposite dead load analysis.  The first value in the list is for the bay between girders 1 and 2.  Also see BRACING NOT BOLTED FOR DEAD LOAD 1, in which case all intermediate bracing in all bays is unbolted for construction loading.
