    Bolts torque requirement ?

    Erection team are asking for these values and I was never asked for them before , I search in AISC and didn't find any related info. Bolts used are A325M for bearing type connections, can someone tell me what exactly is required to provide this information ? Thank you very much in advance.

    Best steel column-beam-brace joint to the column weak axis (web direction) ??

    Thanks for your contributions. I have a question regarding extended plates, If I'm a fabricator with connections design scope, EOR is giving me only a criteria for connections design (no Staad.Pro model), in that case who is responsible for checking column for eccentricity moment ? That's...

    Best steel column-beam-brace joint to the column weak axis (web direction) ??

    do you mean this one ? It's not similar to the connection I'm asking about I generally want to know why it's not more used compared to UFM or KISS Joints ? Is there a disadvantage that I'm not getting ?

    Use a haunch to avoid local failures of column section or web doublers ?

    As the title suggests , ignoring cost impact & total weight of structure. Would you prefer adding a web doubler to make the panel shear zone safe or use a haunched connection to minimize shear force in the panel zone ? I never liked doublers myself but would like to hear everyone's opinion .

    Best steel column-beam-brace joint to the column weak axis (web direction) ??

    This has turned into a very informative discussion. Can someone give me any design guide/steps for this connection? specially the effect of tension/comp. balance effect on gusset plate ? how can I make sure it will not buckle or twist or any rupture would happen to it ?

    Best steel column-beam-brace joint to the column weak axis (web direction) ??

    Is IDEA STATICA reliable when analyzing all of these connections ? because manual calculations will take really long time

    Best steel column-beam-brace joint to the column weak axis (web direction) ??

    Thank you for your answers. Is there any design guide for the second connection ? Furthermore, if I take the connection further inside the column web to avoid eccentricity , would it be impossible to erect or just little more difficult ?

    Best steel column-beam-brace joint to the column weak axis (web direction) ??

    As the subjects suggests , this joint has been giving me headaches. In the direction of the column main axis, I have a moment connected main beam and I need the back transverse stiffeners in the column. How do I connect the strut and brace in the other direction while maintaining erect-ability...
