Apex Haunch connection with both end plates, both top flange stiffener, filler plates and web stiffeners.
Apex Haunch connection with both end plates, both top flange stiffener, both bottom flange stiffener, bottom flange stiffener, haunch profiles, haunch webs, haunch flanges, filler plates and web stiffeners.
6. Before you start
Create two beams or tapered sections beams.
7. Selection order
For regular beams:
1. Select the main part (supporting beam).
2. Select the secondary part (supported beam)
The connection is then created automatically.
For tapered sections:
1. Select the main part (flange or web of the supporting tapered section).
2. Select the secondary part (flange or web of the supported tapered section).
The connection is then created automatically.
Note: The connection does not support any contour plates so make sure that the selected web or flange isnt a contour plate.
