Design of embeded shear plate with welded side plates

[lancha2001]

Is there any body who has any experience in designing embeded shear plate with welded side plates to sustain heavy shear load on column base. I have design experience for shear lug, but I couldn't find any example for the mensioned one. I don't want to use shear lug for column base seeing shear on both x and y direction since I have to use shear lug in both direction. I attached the embeded shear plate diagram to give you a better idea of what I have in mind.

Thank you all for your suggestions.

I found a design procedure in PCI design handbook.

Thanks guys

I have been using type C for quite awhile and both I and the contractors like it.
