Used to set haunch and chords specifications



SettingDescription
Upper Chord Sets the width and thickness of the haunch top chord.
Lower Chord Sets the width and thickness of the haunch bottom chord.
Web Sets the thickness of the haunch web plate selected from the drop-down list, or entered a new value.
Bt. Chord

When checked, creates a bottom chord instead of a complete haunch. No top flange is created, e.g. for the construction of frame corners.

Disables the Upper Chord setting, and enables Turn and Coped Shape settings.
Turn When checked, and the Bt. Chord (Bottom flange haunch) has been selected as haunch type, the haunch on the topside of the shape is selected.

If the connection appears to be turned, you can rotate it here.

Cone If this field is checked, a tapered haunch is created by fitting the width of the haunch flanges to the support and connection shape and then tapering them. Use the ‘Cone Width’ field to specify a cone width if you have a specific value in mind. However, the ‘Link Size’ field cannot be checked as well.
Link Size If this field is checked, the head width and any existing cone width are fitted to the shape to be connected. Inputs in these fields will be ignored in this case.
Coped Shape

When checked, and you selected Bottom flange haunch as haunch type, the haunch is not made from individual plates but from a coped shape. The shape size corresponds to the connection shape; all other shape size fields are then ignored.

In the neighboring input field, the value sets the head height of the bottom chord. This is the distance from the bottom flange haunch at the end of the cropped shape (analogue to the ‘Haunch Head Width’).

Group When checked, top flange, bottom flange and web plate are arranged to form a group.
Bottom / Top Stiffeners Adds stiffeners to the foot and head points.
  • Bottom Stiffener – When checked, a stiffener is attached to the base point of the haunch of the support shape.
  • Top Stiffener – When checked, a stiffener is attached to the head point of the haunch of the connected shape.
You can select a stiffener type in the list displayed here. Just select a stiffener template, which you previously saved using (Stiffener) tool.
  • When unchecked, the Edit Style icon is enabled.
  • (Edit Style) – Opens Stiffener dialog used to create a new style or get one to use in the Haunch.
Length, Width, Angle.. Sets the haunch length, roof pitch, bottom width, head width and offset. A modification in the input field roof pitch has only an effect if a haunch has been created without supporting shape. In the input field Cone Width you enter a width to which the haunch tapers if required.
You may use , by selecting a haunch connection to transfer existing connection to the connection to be created.
