You may now design a Brace to Column Base Plate Connection in RISAConnection version 8. This connection type combines the original single column base plate with a gusset from a connected vertical brace member. The connection allows tapered or rectangular gussets that frame into either the column flange or web. The location of the workpoint may also be adjusted to match your exact geometry.
The distribution of loading from the brace to the column and base plate is calculated per the AISC Design Guide 29: Vertical Bracing Connections – Analysis and Design section 4.3.
The connection is designed by checking each applicable limit state at each sub-connection interface: the brace to gusset, the gusset to column, and the base plate.
