Originally, the typified moment-resistant connections of the DSTV guidelines were not designed to be subjected to normal force. However, a load of up to 5% of the plastic normal force resistance of the connected beam may be neglected according to the instructions given in the guideline. If the beam contains a higher normal force, a warning message is also given in RF‑/JOINTS Steel - DSTV.
With the additional volume of the 2018 guideline, additional moment-resistant connections of the IM designation were added. In the beam-to-beam connection type, they are also designed to resist the normal forces. If you design such a connection, the normal force resistance design including the MN interaction appears instead of the warning message.
For beam-column connections, the normal force resistance of column components is not included in the table values according to the DSTV guideline. Therefore, the connection must be designed separately again. Consequently, the warning message appears anyway. As an alternative, you can use RF‑/JOINTS Steel - Rigid.
