LIMCON Design Using the EC3

Question

Greetings, 
 Regarding Limcon V3.63.1.16, designing of moment end plate using Euro Code 3, Limcon is referring to the following while performing some of the required checks. 
 
 AS 4100, code and design guide 12. 
 AISC 360-10, design guides 4 and 16

The checks where AS 4100 & AISC 360-10 references are used: 
 CHECK 5 - Bolts in Shear: 
 CHECK 6 - End Plate in Bending: 
 CHECK 7 - End Plate in Shear: 
 CHECK 10/16 - Unstiffened Column Flange Bending at Beam Tension Flange: 
 CHECK 14 - Unstiffened Column Web Buckling at Beam Compression Flange: 
 CHECK 22A - Stiffened Column Flange Bending at Beam Tension Flange: 
 CHECK 23 - Transverse Stiffeners at Beam Compression Flange: 
 
 Please advise why these references are used instead of EC3; since it resulted in deferent nominal connection strength compared to values of EC3 
 
 Sincerely,

Limcon configured for EC3 does not make reference to AS 4100 or AISC 360-10. However, it does make reference to the ASI and AISC design guides mentioned above because it uses the AISC design model for this connection type. Design codes such as EC3 generally do not contain detailed design models for connections. Limcon uses the AISC design model for bolted moment end plates. 
 
RAM Connection 11 (coming out soon) configured for EC3 uses the design model in the BCSA/SCI publication P398.

The two primary standards for Europe in Ram Connection are 
 BS 5950-2000 (British standard) EN 1993-2005 (Europe standard) 
 The BS 5950 code does incorporate BCSA, and column Base Plates are included. Here are the references from the manual:
