I am doing a moment bolted connection design in RAM connection. The moment resistance capacity remains unchange and it shows failure even though i modify the bolting arrangement . I need to pass this in RAM instead of doing a manual checking which i feel is not necessary while having RAM softwareSnap2.docx
If the sign conventions of the forces you have entered are correct, then you may try the following modifications to pass this connection:
1) Add Column web panel zone stiffeners - Supplementary web plates.
Set Position to Both Sides Set Thickness to 16 mm Set Web plates extension to 120 mm Set the required material Set welding electrode Set Support weld size to 16 mm
2) Increase the end plate thickness to 30 mm3) Change bolts to M304) Change Top and Bottom flange weld type to Fillet and set weld size to 12 mm.
With these modifications the connection should pass with ratio 0.99 for the applied forces.
