Stabilizer plate for an extended joist bottom chord

Top of plate: The distance from the workline of the joist to the top of the stabilizer plate (see example ).

Plate length ( length ): The distance between the top and bottom edges of the bottom chord stabilizer plate (see example ). Since the stabilizer plate is rectangular, this could also be defined as the length of the edge of the bottom chord stabilizer plate that welds to the column.

Plate width ( width ): The distance between the edge of the plate that welds to the column and the opposite edge (see example ).

Plate thickness ( thickness ): The distance between the two faces (the largest surfaces) of the bottom chord stabilizer plate (see example ).

Weld: The weld size used to shop weld the length of the plate to the supporting column (see example ). Setting " Weld " to ' 0 ' removes the weld.

Erection hole diameter ( dia ): The diameter (in the primary dimension " Units " or other units ) of the optional erection hole in a joist's bottom stabilizer plate. Per OSHA, the hole is placed 1 1/2 inch (38 mm) from the bottom edge and joist edge of the plate. The hole may be used for guying or plumbing cables. Its default diameter is 13/16 inch (21 mm).

To get an erection hole , you need to set the option " Use erection hole " on the Joist Edit window in " Connection specifications " to ' Yes ' or ' Automatic '. Setting that same option to ' No ' or, possibly, ' Automatic ', removes the hole and also removes the " Erection hole diameter " lock in this leaf.
