  1. End Plate
  2. Cover Plate
  3. Knee Plate
  4. Web Stiffener
  5. Outer flange Stiffener

There are two plate length types: one is by total length and the other is projection.
The distances are numbered in red in the dialog box.

 

 

  1. Projection of rafter from the cover plate
  2. Cover plate top from the rafter flange
  3. Projection of the end plate from the web of the column
  4. Total length of the plate
  5. Projection of the end plate from the web of the column

Note: When Total Length is selected, distance box 3 is not available. When Projection is selected, distance box 4 is not available.

The parts are shown in the image on the left:
  1. End Plate
  2. Cover Plate
  3. Knee Plate

 

 

End plate

You can define end plate properties such as width and thickness.

Cover plate

 
Image
2015_08_18_06_50_463.png
There are two ways to define the cover plate width: one automatically calculates the width from the column/rafter flange width and the other is width defined by the user.

Thickness

 
Image
2015_08_18_06_51_254.png
There are two ways to define the cover plate thickness: one automatically calculates the thickness from the column/rafter flange thickness, and the other is thickness  defined by the user.

Knee plate

Knee plate creation is controlled with a Yes or No option.
You can define properties such as thickness for the knee plate.

Note: When the Knee plate option is set to Yes, a knee plate is created and shown only after the rafter member is updated.

Select Yes in (7) Knee stiffener to create a knee stiffener.

Knee stiffener type

 
Image
2015_08_19_05_01_191.png
Knee stiffener types:
  1. Perpendicular to the flanges of the rafter
  2. Perpendicular to the end plate
  3. Parallel to the column flange

Thickness

 
Image
2015_08_19_05_02_052.png
There are two options for thickness: one to calculate the thickness from the column flange automatically, and the other is width defined by the user.

Length

 
Image
2015_08_19_05_02_393.png
Stiffener length:
  1. Total length of the stiffener to the rafter depth
  2. Length with clearance from the top flange
  3. Length defined from the end plate

Width

 
Image
2015_08_19_05_03_254.png
Stiffener width:
  1. Calculated from the flange
  2. Calculated from the end plate
  3. User-defined

Diagonal stiffener

 

Image
2015_08_19_05_03_575.png

Diagonal stiffener controlled by a Yes or No option.

 

 
Image
2015_08_19_05_04_216.png
Location of diagonal stiffener:
  • First option is based on the offset from the diagonal points.
  • Second option is based on the minimum clearance from the nearest faces of flanges / end plate / cover plate / knee stiffener.

Eaves stiffener

 

Image
