Vertical edge distance: The minimum distance (in the primary dimension " Units " or other units ) from the top or bottom edge of the shear plate to the center of the nearest hole.

Lv = vertical edge distance.

Effect on connection design: The vertical edge distance entered here is the minimum vertical edge distance that connection design applies to shear plates. The minimum applies to shear plates for both beams and joists. If there is a conflict between this minimum edge distance and the per diameter " Default bolt edge distance " in Bolt Design Criteria , connection design uses the larger minimum.

Horizontal edge distance: The minimum distance (in the primary dimension " Units " or other units ) from the center of the nearest column of holes to the free edge of the shear plate. The shear plate's free edge is the edge that is interior to the supported beam or joist and opposite to the edge that welds to the supporting member. When " Keep shear plate symmetrical " is checked, the designed bolts-to-free-edge distance will likely be larger than the distance that is entered here.

Lh = horizontal edge distance.

Effect on connection design: The vertical edge distance entered here is the minimum horizontal edge distance that connection design applies to shear plates. Per AISC, the minimum value for the horizontal edge distance is 1 1/2 inch. This applies to shear plates for both beams and joists. If there is a conflict between this minimum edge distance and the per diameter " Default bolt edge distance " in Bolt Design Criteria , connection design uses the larger minimum.

End connection failure message: Invalid bolt edge distance

Minimum thickness: The minimum thickness (in the primary dimension " Units " or other units ) of the plate used for moment shear plates and beam-to-beam splice plates .

Effect on connection design: When connection design creates a moment shear plate or splice plate, the plate that is used is as thick or thicker than the thickness entered here. How much thicker depends on the shear load on the connection.

Tip: To set the minimum thickness for single-plate shear connections (shear tabs) and through plates, use the Schedule of Minimums for Single-Plate Shear Connections .

Standard hole type: Standard round or Short slot or Long slot or Oversized round or User slot #1 or User slot #2 .

Effect on connection design: The hole type entered here applies to the connection design of shear plates (beams & joists). Connection design determines the specific hole size applied to shear plates per " Connection design method " specifications, based on the hole type entered here and the diameter of the bolt that is used.

Non combined vertical brace hole type: Match beam or Standard round or Short slot or Long slot or Oversized round or User slot #1 or User slot #2 . This applies when the option to " Combine beam/vbr shear plates " is set to ' No '.

A vertical brace to a beam and column with a non-combined shear connections on the beam and vertical brace gusset plate.

' Match beam ' instructs connection design to create the shear plate on the gusset plate using the same " Standard hole type " that is specified for the beam.

Selecting one of the other menu choices (' Standard round ' or ' Short slot ' or ' Long slot ' or ' Oversized round ') instructs connection design to create all non-combined shear plates (except user and user defined) using that specified hole type.

Shear plate alignment: Opposite or Offset . This applies to shear plates on the same beam (or joist) when the " Shear plate/tee side " (beam) or " Shear plate side " (joist) is set to ' Automatic ' under the " Connection specifications " on the beam/joist window or at Home > Project Settings > Job > Connections > Auto Standard Connections or User Defined Connections

' Opposite '
' Offset '
To get the results shown here, the " Shear plate/tee side " must be set to ' Automatic ' for both the left and right ends of a beam. For a joist (not shown), " Shear plate side " must be ' Automatic '.

When the " Shear plate/tee side " or " Shear plate side " is ' Automatic ' (both ends) . . .

' Opposite ' designates that both the left-end and the right-end shear plates be fastened to the near side of the web of the beam (or knife plates of the joist).

' Offset ' designates that the shear plates be fastened on opposite sides of the beam's web (or knife plates of the joist). The left-end shear plate will fasten to the near side of the beam or joist. The right-end shear plate will fasten to the far side.

Keep shear plate symmetrical: or . This applies to shear plates for beams or joists. It does not apply to " Extend past flange " shear plate connections and may also not apply to skewed shear plate connections.

Keep symmetrical
Keep symmetrical

If this box is checked ( ), connection design centers the column of holes between the fixed edge and the free edge of the shear plate. To design a plate that is symmetrical, connection design may add extra space between the bolt column and the free edge of the shear plate, thus increasing the width of the plate. The free edge of the shear plate is the edge that is interior to the supported beam or joist.

If the box is not checked ( ), connection design may create shear plates that are not symmetrical. The distance from the center of the holes to the free edge of the shear plate will likely be smaller, closer the Horizontal edge distance ."

Cope on connections that extend past flange: or . This applies to perpendicular beam-to-beam shear plate connections when the " Extend past flange " box is checked.

Cope ...
Cope ...

If this box is checked ( ) and the plate is extended past the flange of the supporting beam, connection design copes the shear plate and not the supported beam.

If the box is not checked ( ), connection design cuts the shear plate square and copes the supported beam to clear the shear plate.

Cope extended shear tabs to reduce beam cope: or . This applies to beam-to-beam shear plate connections when the " Extend past flange " box is not checked and ' Both flanges ' is selected for " Extend size to ."

Cope ...
Cope ...

If the box is checked ( ), the shear tab is coped to reduce the cope length on the beam.

If the box is not checked ( ), the shear plate is not coped.

For a shear plate to be coped, it must stick out at least 1/2 inch past the supporting beam flanges. The supported beam's " Field clearance " or " Minus dimension " must be sufficiently large for the shear plate to stick out this much.

Extend connection and cut flange flush: or .

Extend ...
Extend ...

If this box is checked ( ), connection design will, if necessary to create a connection with sufficient capacity, cut the flange flush to the web so that the shear plate can be extended to accommodate another row of bolts.

If the box is not checked ( ), connection design does not extend a shear plate and cut the flange flush in this manner. Connection design may still be able to create a connection with fewer bolt rows (for example, by using larger-diameter bolts), or it may fail the connection.

Combine beam and vertical brace shear tabs: or . For a vertical brace to a beam and column, connection design creates a shear plate for the gusset-to-column interface if the beam connects to the column with a shear plate. This field lets you set the default for whether or not you want the shear plates combined into a single plate. It applies when " Combine beam/vbr shear plates " is set to ' Automatic ' under the shear " Connection specifications " on the Beam Edit window or at Home > Project Settings > Job > Auto Standard Connections or User Defined Connections .

  Combine ...
  Combine ...

When " Combine beam/vbr shear plates " is ' Automatic ' . . .

If this box is checked ( ), connection design creates a shear plate that connects both the beam and vertical brace gusset plate to the column. The shear plate uses the " NM bolt diameter " and " NM bolt type to supported " that are set for the beam.

If the box is not checked ( ), connection design creates two separate shear plates, one to connect the beam to the column, the other to connect the vertical brace gusset plate to the column.

Skew holes in shear tabs: or . This applies to shear plates on slightly sloping beams or joists. For beams, the box also needs to be checked at Home > Project Settings > Fabricator > Detailing > Member Detailing Settings > the " Beams " section > "   Square cut ends of sloped beams ." It applies when " Skew holes in plate " (beam) or " Skew holes in plate " (joist) is set to ' Automatic ' under " Connection specifications " on the beam/joist window or at Home > Project Settings > Job > Auto Standard Connections or User Defined Connections .

  Skew holes ...
  Skew holes ...

When " Skew holes in plate " or " Skew holes in plate " is ' Automatic ' . . .

If this box is checked ( ). connection design creates the shear plate with bolts that run parallel with the sloping member's web (square-cut beam) or knife plate (joist).

If the box is not checked ( ), connection design creates a shear plate with bolts that are parallel to the edge of the shear plate that welds to the supporting member.

Center shear tee on beam centerline: or . This applies to shear connections with " W Tee " selected as the " Material type " and ' Bolted ' selected for " Attachment ."

  Center ...
  Center ...

If this box is checked ( ), connection design centers the columns of holes on a bolted shear tee with respect to the center line of the beam.

If the box is not checked ( ), connection design centers the holes with respect to the center of the stem of the tee.

Use expanded vertical bolt spacing: or . This can apply to a ' Non-moment ' shear plate or shear tee connection. It applies when ' Automatic ' is the choice made to " Use expanded vertical bolt spacing " (beam) under the " Connection specifications " on the beam/joist window or at Home > Project Settings > Job > Connections > Auto Standard Connections or User Defined Connections .

Use expanded ...
Use expanded ...

When " Use expanded vertical bolt spacing " is ' Automatic ' . . .

If this box is checked ( ), connection design attempts to expand the vertical spacing of bolts to 1.5 times or 2 times the Home > Project Settings > Fabricator > Detailing > Connection Erectability Settings > " Bolt spacing " that is set per bolt diameter. The program may also adjust to a spacing other than 1.5 or 2 times the standard bolt spacing in order to accommodate piecemarking issues, loading conditions and unusual geometries.

If this box is not checked ( ), connection design uses the Home > Project Settings > Fabricator > Detailing > Connection Erectability Settings > " Bolt spacing " that is set per bolt diameter

Tip: Expanded vertical hole spacing can help to reduce fabrication costs by minimizing the number of rows of bolts in shear plates and shear tees.

Cope dissimilar through plate sides: This applies to shared shear through plates with sides of unequal depth.

VIDEO

Two beams with single-plate shear connections frame to an HSS column. These connections are changed to through plates, resulting in a tapered shear through plate connecting the two beams through the column. Then " Cope dissimilar through plate sides " is checked, giving a coped shear through plate. ( SDS2 Detailing , v2018)


Cope dissimilar . . .
Cope dissimilar . . .

If this box is checked ( ), the cut between the two dissimilar sides of the shear through plate is a cope, which is a 90-degree cut with a radiused corner. The cope is made at the side of the through plate that is less deep.

If this box is not checked ( ), the cut between the two dissimilar sides of the through shear plate is an angular cut.

Related options on this window: " Cope radius " and " Free edge through plate projection ."

Weld split plate to through plate: or .This applies when " Weld split plate to through plate " is set to ' Automatic ' under " Connection specifications " on the Beam Edit window or at Home > Project Settings > Job > Auto Standard Connections or User Defined Connections .

Weld split plate ...
Weld split plate ...

When " Weld split plate to through plate " is ' Automatic ' . . .

If this box is checked ( ), connection design welds split plates to the through plate.

If this box is not checked ( ), connection design does not weld split plates to the through plate.

Bevel shear plate as required: or . This applies when " Bevel shear plate as required " (beam) or " Bevel shear plate as required " (joist) is set to ' Automatic ' under " Connection specifications " on the beam/joist window or at Home > Project Settings > Job > Auto Standard Connections or User Defined Connections . Per AISC, beveling of a 5/16- to 3/8-inch shear plate is required when the dihedral angle is between 45 and 60 degrees. A 1/2-inch shear plate is required to be beveled from 22° to 45° from perpendicular. This applies to beams or joists framing skewed to beams or to columns. See What "as required" means.

VIDEO

SDS2 connection design's compliance with AISC 14th Edition, pages 10-176 and 10-177 is demonstrated by adjusting the framing angle of beams with shear plates that are 3/8- and 1/2-inch thick. ( SDS2 Detailing , v2018)


  Bevel shear plate ...
The shear plate is beveled.
  Bevel shear plate ...
The shear plate clashes with the web.
The dihedral angle is the angle between the web center lines of the intersecting beams. Model > Ruler can measure the acute angle between two member lines.

When " Bevel shear plate as required " or " Bevel shear plate as required " is ' Automatic ' . . .

If this box is checked ( ) and shear plates are beveled " as required " (see below), " Bevel precision " sets the decimal precision (places after the decimal point) to which the shear plate is beveled.

If this box is not checked ( ), shear plates that are required to be beveled will not be beveled.

What "as required" means: A 5/16- to 3/8-inch thick shear plate is required to be beveled if the dihedral angle between the connecting members is less than 60 degrees. This is another way of saying that it is required to be beveled if the shear plate is skewed at an angle from perpendicular that is greater than 30 degrees. AISC specifies that a 1/2-inch shear plate be beveled from 22° to 45° from perpendicular. See AISC 14th Edition, pages 10-176 and 10-177.

When beveling of a shear plate is not required, the shear plate will not be beveled, regardless of the choice made here. Also, when beveling is not required, the shear plate will not clash with its supporting member's web or flange. For dihedral angles from 60° to 90°, a 5/16- to 3/8-inch shear plate is not beveled.

Bevel precision: 0 or 1 or 2 or 3 or 4 . This sets the decimal precision (places after the decimal point) to which a shear plate will be beveled when " Bevel shear plate as required " (beam) or " Bevel shear plate as required " (joist) in " Connection specifications " is set to ' Yes ' or, possibly, to ' Automatic '.

' 0 ' bevels the shear plate to the nearest degree ( x ° ).

' 1 ' bevels the shear plate to the nearest tenth of a degree ( x.x ° ).

' 2 ' bevels the shear plate to the nearest hundredth of a degree ( x.xx ° ).

' 3 ' bevels the shear plate to the nearest thousandth of a degree ( x.xxx ° )..

' 4 ' bevels the shear plate to the nearest ten-thousandth of a degree ( x.xxxx ° ).

Cope radius: A distance in the primary dimension " Units " or other units . This applies when a shared through plate has been coped due to the option " Cope dissimilar through plate sides " being checked.

Vertical and horizontal construction lines at the vertex points ( vtpt ) of the cope meet at the center point of a construction circle whose " Radius " is equal to the " Cope radius ."

Free edge through plate projection: The distance (in the primary dimension " Units " or other units ) that the through plate projects past the outside HSS wall on the free-edge side of a single-sided through plate. As shown the bottom example, this projection also applies when a shared through plate has been coped . The projection is needed to accommodate weld.

VIDEO

In the model, it is confirmed that the free edge of a coped through plate projects 1/2 inch beyond the face of an HSS column, a distance which matches the " Free edge through plate projection " distance specified in Shear Plate Settings . ( SDS2 Detailing , v2018)


p = free edge through plate projection. In this example, the projection is for the free-edge side of a single-sided through plate.
In this example, the " Free edge through plate projection " positions where the cope begins on the coped side of a shared through plate.

End of beam to face of shear tee setback: The distance (in the primary dimension " Units " or other units ) that the end of the beam is to be set back from the face of the shear tee connection.

s = end of beam to face of shear tee setback.

A related setting: " Shear tees " ( Field Clearances ).

Orientation of stiffener: Inline or Perpendicular . This applies when the box is checked for " Stiffener opposite " (joist) or " Stiffener opposite " (beam) in the " Connection specifications " for a joist or beam with a shear plate connection that is framed skewed to a supporting beam. Also in connection specifications, something other than ' As required ' needs to be selected for " Extend size to ."

' Inline '
' Perpendicular '
The above screen shots were taken from beneath the top flange of the supporting beam. Since the joist flush frames to the beam, the view of the joist is also beneath its top of steel.

' Inline ' aligns the stiffener at the same skew as the shear plate.

' Perpendicular ' orients the stiffener perpendicular to supporting beam.

Note: If the supported beam or joist is perpendicular to the supported beam, then either choice (inline or perpendicular) will produce the same results.
