" Column Plate " connection design locks

An auto base/cap plate to a beam or joist is designed per " Column Plate " locks. The " Plate length " is parallel with the workline of the beam or joist. The " Plate width " is symmetrical around the workline of the beam or joist.

• In the general case (top example), the column work point divides the auto base/cap plate into left and right sections .
• The left and right sections DO NOT have to be mirror images of one another.
• A special case (second example) is for a column whose flanges are perpendicular to the workline of the beam.
• The plate in the second example is divide into left within flange and right within flange and right outside flange and right outside flange sections.
• The left edge of the base/cap plate is the edge nearest to the left end of the beam or joist.

(a column, auto base/cap plate connection, to a beam or joist) (" Input connection type " = ' Auto base/cap plate ' or ' Auto standard ' or ' User defined ') (" Section size " = any valid shape) (" Column rotation " = most any -- see "The general case ...")

" Column Plate " ( the general case )

The general case applies to all columns except for a column whose flanges are perpendicular to the beam's workline. For example, it applies to HSS, pipe or tube columns. It also applies to wide flange columns whose " Column rotation " is set so that the flanges of the column are not perpendicular to the beam.

(a column to a beam) (" Input connection type " = ' Auto base/cap plate ') (" Section size " = any valid shape with flanges) (" Column rotation " = column web aligned with beam workline)
" Column Plate " ( a special case )	This special case applies to a column whose " Section size " is a wide flange , S shape or welded plate wide flange . The " Column rotation " is such that the flanges of the column are perpendicular to the workline of the beam. In other words, the web of the column is parallel with the beam. Another special case : Cap Plate (vertical brace)

Left bolts (outside flange)

The connection design locks in this section apply to a wide flange, S shape or welded plate wide flange column whose flanges are perpendicular to the workline of the beam. See " Cap Plate ". Warning : If a vertical brace gusset plate has been welded (by connection design ) to the left portion of the auto base/cap plate, the left, outside flange bolt group should be controlled with the " Cap Plate " connection design locks and the locks in this section should be unlocked ( ).

The connection design locks in this section apply to a wide flange, S shape or welded plate wide flange column whose flanges are perpendicular to the workline of the beam. See " Cap Plate " . Warning : If a vertical brace gusset plate has been welded (by connection design ) to the right portion of the auto base/cap plate, the right, outside flange bolt group should be controlled with the " Cap Plate " connection design locks and the locks in this section should be unlocked ( ).
