Connection N3 – Design of net cross-section For a connection in tension, the design plastic resistance of the net cross- section at bolt holes should be verified only for a connection in tension. EN 1993-1-8 3.4.1 (1) c) 3.3.7. Connection N3 – Design of block tearing Given that this connection is in compression it is not necessary to execute the design for block tearing. 3.4. Connection N1 – Back-to-back double-angle diagonal member N1 to gusset bolted connection We have a shear connection in tension to be designed as Category C. The sizes of the components of this connection and the positioning of the holes are shown on the Figure B.21. The section DD is identical to the section CC of the connection N3 (See Figure B.11).
