Steel connection

[85778RSAPRO_2012_0F]

Hi

I tried to make a connection for 2 beams. Section forces can be seen in screenshot_1. These forces ar not the same during the calculation of connection. See screenshot_2

Whare is the problem?

Thanks

It is assumed that the connection works in one plane.

BTW: Is anybody familiar with EC provisions for verification of this type connection for bi-directional bending? I don't think that that Eurocode addresses such design situation but perhaps I'm missing something.
