    Stiffening Of Wide-Flange Column At Moment Connections

    Hi, I am trying to determine the column strength connected to a beam with end plate moment connection as per the AISC Design Guide - 13. But this design guide offers the equation for calculating "bs" only for two cases - 1. Four Bolt Unstiffened Extended End Plate Connection. 2. Eight Bolt (4+4)...

    Thickness Limitations for welded plates

    its not about the minimum plate thickness. Its about width to thickness ratio. As per AISC i can find compact non compact and slender elements. One more thing. Which is plate girders. If my section elements are slender its strength is reduced as per code. But it does not restrict thickness...

    Thickness Limitations for welded plates

    "I also feel web and flange plates are too slender as per your rules of thumb." Then it will be considered as slender section element and designed that way. Isn't it?? "These structures may land in deep trouble with long-term durability problem after a time, mainly in highly corrosive and...
