Shear connections are system connections that may be applied, in a full-featured SDS2 program , on the end of a W or C or tube (HSS rectangular) beam under beam-to-beam or beam-to-column framing situations.
Shear thru connections may frame into HSS rectangular or HSS round columns.
W tee shear connections and built-up plate tee connections must be shop welded if framing to a tube column.
W tee shear connections and built-up plate tee connections must be shop welded if framing to a tube column. Bolted-bolted W tee or pate tee connections can have a different " NM bolt type to supported " and " NM bolt type to supporting "
Single-plate shear connections and bolted-bolted W tee or built-up plates tee connections may optionally be detailed on (shop attached to) the supporting member (column or beam). Or they can be detailed on (shop attached to) the supported beam. Click here for more information.
Single-plate shear connections are often used in skewed framing situations. W tee and built-up plates shear connections can be designed on a sloping beam but not on a skewed beam.
For a vertical brace framing to a beam and column, a shear plate is designed for the gusset-to-column interface if the beam connects to the column with a shear plate. The beam's "
"
During connection design in a full-featured SDS2 program , the program will look to relevant setup options and shear connection type specifications to determine shear plate design. If necessary to meet loading conditions, the program will first increase rows of bolts, then bolt diameter and last plate thickness to design a connection that works. If a tee connection has been designated and no appropriate WT material is entered under ' Preferred WT Sizes ', the program will design a sheer plate connection instead.

" Connection specifications " are read-only in SDS2 review stations. You can find this set of conn specs on the Beam Review window when ' Shear ' is the " Input connection type ." For auto standard or user defined connections, conn specs are not on the Beam Review window, but can be found at Home > Project Settings > Job > Auto Standard Connections or User Defined Connections. |
Material type: Plate or W Tee or Built-up plates . This " Connection specifications " option sets the material for connecting the supported beam to the supporting column or beam when the " Input connection type " on the Beam Review window is ' Shear '.

| A moment connection can be designed on non-auto standard shear connections that are any of these types. |
In a full-featured SDS2 program . . .
' Plate ' specifies that connection design create a single-plate shear connection (a shear tab connection). A single-plate shear connection can be designed in skewed framing situations.
' W Tee ' instructs connection design to attempt to create a shear W tee connection. For a shear tee connection to be designed, there must be W tee material entered to Home > Project Settings > Fabricator > Standard Fabricator Connections > Preferred WT Sizes . If no WT material is in the list (or if an appropriate size is not listed), connection design defaults to plate material for the connection. Shear tee connections must be shop welded to the column if framing to a HSS/TS column. Also see: " Center shear tee on beam centerline " in Shear Plate Settings .
' Built-up plates ' configures connection design to create a built-up tee connection composed of two plates that are welded together. The " Attachment " and " Attached to " options apply to this type of material in the same way that they apply to ' W Tee ' material. Also, just like ' W Tee ' material, built-up plate material can only be used in non-skewed framing situations.
Attachment: Bolted or Welded . This " Connection specifications " option applies when ' W Tee ' or ' Built-up plates ' is selected as the shear connection " Material type ." The option can be found on the Beam Review window and at Home > Project Settings > Job > Auto Standard Connections and Home > Project Settings > Job > User Defined Connections .

' Supported ' specifies that the connection attaches in the shop to the supported beam (this beam). For a bolted W tee or built-up plates shear connection, this means that the connection shop bolts to this beam and field bolts to the supporting beam or column. Connection design applies the field clearance entered for " Shear tees " in Field Clearances . For a shear plate connection, the plate shop bolts to this beam and field welds to the supporting member. A supporting member is not required to get a connection, and a 3D field weld will be generated in the model even if there is no supporting member.
' Supporting ' specifies that the connection attaches in the shop to the supporting member. For a W tee or built-up plates connection, the tee flange shop bolts to the supporting beam or column and its stem field bolts to the supported beam (this beam). For a shear plate connection, the plate shop welds to the supporting member and field bolts to this beam. The shop welds are shown in the model, and shop welding instructions are provided on the member detail. Weld specifications are also provided in the Connection Design Calculations Report or Expanded Connection Design Calculations Report .
Shear plate/tee side: Automatic or Near side or Far side or Both . This " Connection specifications " option reads " Shear plate side " when ' Plate ' or ' Built-up plates ' is selected as the shear connection " Material type ." It reads " Shear tee side " when ' W Tee ' is selected.

In a full-featured SDS2 program . . .
' Automatic ' specifies, when Home > Project Settings > Fabricator > Standard Fabricator Connections > Shear Plate Settings > " Shear plate alignment " is set to 'Offset ', that the shear plate (or tee stem) be designed on the near side of the web if this is the left end of the beam, on the far side if this is the right end of the beam. When the " Shear plate alignment " is ' Opposite ', then setting the left end to ' Automatic ' places the left-end plate/tee on the near side of the beam, and setting the right end to ' Automatic ' places the right-end plate/tee on the near side of the beam.
' Near side ' or ' Far side ' specifies that the shear plate or thru plate (or tee) be designed on the side of the supported beam's web that is selected. The near side is the face of the web that you are facing when the left end of the beam is to your left and the right end of the beam is to your right.
' Both ' applies when ' Plate ' is selected and the " Section size " is a tube (HSS rectangular).
Flange splice plates on: This member or Opposite member . Flange plates can be designed when ' Bolted ' is the " Moment type " set for this end of this beam in its " Moment " leaf. If the supporting beam is the same depth as the supported beams (they are shown here as different), the choice made here applies to the bottom flange plate as well as the top flange plate.

In a full-featured SDS2 program . . .
' Automatic ' specifies that connection design apply the choice made to Home > Project Settings > Fabricator > Standard Fabricator Connections > Shear Plate Settings > " Use expanded vertical bolt spacing ."
' Yes ' permits connection design 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. Connection design 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.
' No ' instructs connection design to use 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.
Combine beam/vbr shear plates: Automatic or Yes or No . When this end of this beam frames to a column with a single-plate shear connection and a vertical brace frames to this beam and that same column, connection design can either create one combined shear plate or two shear plates (one for the beam-to-column interface, the second for the gusset-to-column interface).

Load calculation 264 applies when the shear plate connection on this end of the beam welds to an HSS beam and the supported beam (this beam) has a " Tension load " applied to it |
In a full-featured SDS2 program . . .
' If required ' results in design calculations 265 and 264 being potential causes of connection failure when applicable. Design calculation 265 is applicable when the shear plate connection on this end of the supported beam has a " Tension load " applied to it and that shear plate welds to a supporting HSS column. Calculation 264 is applicable when the shear plate connection on this end of the supported beam (this beam) has a " Tension " load applied to it and the shear plate welds to a supporting HSS beam.
' For supporting column ' results in calculation 265 being a potential cause of connection failure in the design of the shear plate on this end of the supported beam (this beam) when that end has a " Tension load " applied to it and the shear plate welds to a supporting HSS column. Calculation 264 will not result in connection failure of a shear plate to an HSS beam, though the calculation will still be done, and a for-information-only note reporting the results of the calculation will be provided, when applicable, in both design calculations reports.
' For supporting beam ' results in calculation 264 being a potential cause of connection failure in the design of the shear plate on this end of the supported beam (this beam) when that end has a " Tension load " applied to it and the shear plate welds to an HSS beam. Calculation 265 will not result in connection failure of a shear plate to an HSS column, though the calculation will still be done, and a for-information-only note reporting the results of the calculation will be provided, when applicable, in both design calculations reports.
' Never ' results in calculations 265 and 264 still being performed, if applicable, but not ever causing the connection to fail. In the Connection Design Calculations or Expanded Connection Design Calculations , the results of the check will be reported with a parenthetical, for-information-only note such as "(Allowable local axial transverse force on the HSS wall: K1, (264) 8.7 kips )" for a beam. For a column, the parenthetical note will be something like "(Allowable local longitudinal axial force on the HSS wall: K1, (265) 21.1 kips )."

' Inside wall ' embeds the plate in the concrete wall .
' Outside wall ' locates the plate flat to the wall.
Bevel shear plate as required: Automatic or Yes or No . Per the AISC, beveling of a 5/16- to 3/8-inch shear plate is required when the dihedral angle is between 60 and 45 degrees. A 1/2-inch shear plate is required to be beveled from 22° to 45° from perpendicular. See "What 'as required' means."

| The dihedral angle is the angle between the web center lines of the intersecting beams. Model > Ruler can measure the angle between two member lines. |
In a full-featured SDS2 program . . .
' Automatic ' specifies that connection design apply the choice made to Home > Project Settings > Fabricator > Standard Fabricator Connections > Shear Plate Settings > " Bevel shear plate as required ."
' Yes ' configures connection design to bevel the shear plate "as required" (see below).
' No ' instructs connection design to not bevel the shear plate.
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. This means that for dihedral angles from 60° to 90°, a 5/16- to 3/8-inch shear plate will not be beveled.
