    Castellated Beams - Custom

    Hi All,

    Can someone explain so me, what all these "CASTELLATED BEAM PARAMETERS" stand for. I want to create a diff family. I need to create a 609x140x39 I.

    Example

    d1 -
    bf -
    1t -
    f1 -
    tw1 -
    k1 -

    Its crazy.

    Thanks

    They relate to the beam properties.

    Castellated Beams - Custom-steel-sections-w-shape-big.png

    d = height
    bf = flange width
    and so on

    Since castellated beams are made up of two pieces that can be different size members you need to be able to select the sizes independently

    d1=height(top)
    d2=height(bottom)
    etc

    if you look at the OOTB beam the parameters in the profiles are linked to the different family parameters

    I would recommend opening the Manual of Steel Construction and flipping to the Dimension & Properties section. In my book its the first section.

    two questions, me being the curious type: Is the MoSC available in metric format or is this US documentation? And, what's the current issue of the MoSC? I'm using the 1980 8th edition. Probably should spring and upgrade

    That image helps a lot. Not I can refer to steel handbook for properties!

    Where did you get that picture if I may ask.

    Thanks a lot for the help

    google

    that is for a wide-flange beam but the castellated beams are frequently composed of two WF sections.

    I’m not sure what the latest edition is, but I’m using this pdf document (2002 edition) for all of my steel needs. The table with US standard sizes (imperial and metric) begins on page 127.
    …oh, and it’s free
