Pinned end plate to column

The detail scheme:

Pinned end plate to column detail

The bearing capacity of the connection is given by the minimum

of following vales :

• The shear resistance of beam web F_vbw,Rd (usually critical component for this type of connection)

The shear length of beam web

• The resistance of n bolts nF_b,v,Rd
• The bearing resistance of bolts in end plate nF_b,b,Rd (can be calculated as a sum of bearing resistances of end and intermediate bolts for materials with sufficient ductility)
• The shear resistance of welds F_w,v,Rd
• The shear resistance of end plate V_p,v,Rd in the cross-section with gaps. This can be neglected if A_v,net/A_v> f_y/f_u. In the end plate cross-section is considered only a half of the force in a beam.

The bending resistance and the interaction with shear may be limiting for long end plates.

Cross-section of end plate with gap

The connection may be considered as a pinned one if the beam rotation does not cause the contact of bottom flange with a column The rotation capacity is greater than rotation of simple beam

Rotation of beam end

The remaining tensile resistance for the interaction of tension and shear shall be able to transfer full plastic moment resistance of connected end plate. Therefore, the thickness of the plate should be limited

Where d is bolts diameter. Welds are designed in that way, that they are able to transfer full plastic resistance moment of the plate in tension.
