Final Design
| Setting | Description |
|---|---|
| Diagonal Stiffeners | RAM Structural System does not design the diagonal web stiffeners. However, the program does indicate where these are required and also reports the magnitude of the horizontal shear in the panel-zone section. |
Results
- Panel Zone
- Diagonal Stiffener Req'd to Resist = The horizontal shear force that the diagonal stiffeners are required to resist.
- Required Stiffener Area
- This is the total area of the two stiffeners required at a location to meet the bearing and tension requirements. The reported area accounts for the cope dimension, which reduces the area of the stiffener at the column flange. The smaller of the column and the stiffener yield strength is used to calculate the required area. Note the stiffener yield strength specified by the engineer is not modified according to the final thickness the stiffener.
Stiffener Design
Where a full-length stiffener is required to resist web buckling, then the design is performed according to specification 8.7.1. The 'stiffener column' dimensions are calculated as prescribed in these sections. The smaller of the column design yield strength and the stiffener nominal yield strength is used to perform the check. Refer to the technical notes and the joint criteria section for more information on the stiffener design.
