Delete Type 10 or 11 Stiffeners (Alt Web)

Always consult a Designer before removing a Type 10 or 11 Stiffener.

This option is used to insert a new member 9" away from the Type 3, 9 Stiffener so the haunch member can have a different thickness than the rest of the member. The haunch web thickness will be changed to the alternate web thickness provided by frame design.

From the toolbar select the “Geometry Tools” (hammer icon)

1. Select the Frame that will have the stiffener removed from the Active Frame list. 2. Select the Member ID that has the Type 10, or 11 stiffener. The screen should show the member selected. 3. Select Add Member – Delete Type 10, 11 Stiffener in the Intersection Methods box. (When using this option, there is no need to insert lines or select an element) 4. Select the Modify Frame check box. 5. Select the Intersect button and the intersection points should be shown in the Intersection Points list and the member should be modified. 6. The Stiffener should now be removed and the Alternate Web thickness applied to a new Web Member

Note: Revise weld size only if required to satisfy min weld size based on material thicknesses Increase the Knee Plate to Web weld as necessary to Minimum Weld size based on the thickness thinner part joined. Example: Web Thk= 1/2, Knee Plate Thk = 3/4, Weld = Fillet 3/16-2-x-x Example: Web Thk= 5/8, Knee Plate Thk = 1, Weld = Fillet 1/4-2-x-x
