Default End Plate Connection Design - Limitation

In the design programme, why is the END PLATE DEPTH limited to the Beam Depth between fillets?

This applies to Cleats & Fin Plates but not to an End Plate, I think.

Is this a Gremlin or have I missed an earlier explanation?

This is by design since the connection is assumed to be 'simple', i.e. the supported beam end can rotate without transmitting a significant moment to the supporting member. This rotation is allowed for by intentional deformation of the end plate.

Thanks for a very quick reply.

I tend to fit the end plate at the very top (ie top of plate to top of beam = 0). Is this therefore undesirable and ought I to fit the plate within the net web depth - or am I getting too fussy ?

OR

Is fitting a full depth plate in fact WRONG !? LDS

On checking back in the 'Green Book' (p.83), full depth plates also welded to the beam flanges can be used and will provide useful additional shear capacity. In this case it is particularly important that the detailing requirements of Check 1 are satisfied so not to invalidate the design assumptions, in particular (except for very small sections), 8mm or 10mm end plate and bolt gauge (cross pitch) of 90-140mm.
