MSTower Welded Connection

Hi,

I am modelling a 3 faced tower which has horizontal and diagonal bracing members welded to the tower legs. When I run the non-linear analysis there are ineffective or buckled members. I checked the member forces for the brace members which are circular bars and they have no forces. I suspect the brace members have not been accounted for in the analysis leading to ineffective members during the analysis.

 Help on this will be much appreciated.

 I have tried to attach the MSTower model but get errors.

Thanks.
