    Design of Steel Haunch Bolted End Plate Moment Connection

    We have decided to switch to a fully welded (CJP) WF bracket instead of the bolted bracket detail that was proposed. We'll have full width stiffeners at the column and on the bracket under the girder.

    Design of Steel Haunch Bolted End Plate Moment Connection

    Actually our load on the bracket is more like 106k, not 131k, but still significant. It has to be constructed in this manner because we have a 2nd lower crane operating below, which is sitting on it's own column. The upper crane has a 50T capacity.

    Design of Steel Haunch Bolted End Plate Moment Connection

    Thanks for the replies. P = 131k. SteelPE - Yes, fatigue is a concern. Isn't it always with crane rail structures? That's not a bad idea, though. I take it you added stiffeners to the column at the outrigger flanges, and just designed it like a FR moment connection?

    Design of Steel Haunch Bolted End Plate Moment Connection

    Looking for advice on the design of the attached connection. Steel haunch bolted to column, supporting crane rail beam. See pic. I can't find a design example anywhere in AISC specific to this configuration. It's basically an end-plate bolted moment connection, but I need to design all...

    Strip Footing: Transverse Steel Slways Necessary?

    Thanks for all the replies. Its interesting that many of you have your own way of doing it, and there doesn't seem to be a consensus as far as the 'proper' way to do it. This, of course, is also what I find in practice when reviewing drawings produced by other A/E firms. Another thing I have...

    Strip Footing: Transverse Steel Slways Necessary?

    Obviously I made a typo in the thread title. It should read "Strip Footing: Transverse Steel Always Necessary?" Thanks.

    Strip Footing: Transverse Steel Slways Necessary?

    Let's say you have a small continuous strip footing (wall footing), with a very nominal (small) load. Something like 16" wide x 12" deep with an 8" CMU wall bearing upon the footing. Granted you'll have at least 2 continuous #4 bars longitudinally, but is it really necessary to have transverse...

    Controling Mold During construction

    The way to 'protect' the project from mold growth would have been to keep the rain out, which your GC failed to do. Now, what you can do is try to remediate what damage has been done, and attempt to slow or stop whatever mold growth may already be occuring. This has become a hot topic in the...

    Looking for Old Steel Channel Properties - Please Help

    Thanks for everyone's help. RAY72, thanks for the posts, but I'm afraid the weight per foot doesn't match up with your suggestions. I have also talked to someone at AISC, and they're telling me that it doesn't exist. So, I'm thinking it must be an aluminum shape (even though the plans make no...

    Looking for Old Steel Channel Properties - Please Help

    I'm trying to find an old book or publication that would have old steel channel properties. I have found a few books/publications that have old steel shape properties, but they typically only have wide flange shapes. The particular section I'm trying to find is a C8x4.7. This shape is...
