I think some of you above need a thanks from me – getting my head out of the sand.

I have also attached a sketch. Please first log in with a verified email before subscribing to alerts.
JAE, Still good advice, since I am doing the calcs in Mathcad to semi-automate the design, I am still going to check the section for it’s compactness, however there’s also a simplified clause for rectangular sections I will check out.
Their thickness is generally driven by bearing checks on the pin hole that make this plate much much stockier vth typical structural elements.

For a square plate, like your lug, local buckling is not possible. Back-calculate a t required to ensure a compact behavior and you go from there. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. bthh

The next available drill size will be used to make the hole slightly larger than the pin. Same the document is revised or amended, you will be notified by email. Any help would be appreciated.
Almost invariably, pin bearing, shear and yielding in the area of the pin, and good quality welding detailing controls the design of lifting lugs. We have no amendments or corrections for this standard. As the voice of the U. It’s easy to join and it’s free. The provisions in this Standard apply to the design or modification of below-the-hook lifting devices. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
I think what I posted above is correct but WillisV and others posts are right on – buckling isn’t really an 200 with lugs like this unless the plate is thin and the lug is really long and extended.
Download Now White Paper: I have never seen a lifting lug that would not be classified as compact by a long shot. Already Subscribed to this document.
For now, I am working on a single case and detailing the calculations. Hi Everyone, Baseed on thread Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Usually the “b” is the length of the free, unstiffened edge which undergoes compression. In your case, I would see the b distance as the straight vertical edge to the base center of hole to base weld line. WillisV, Agreed, this makes sense to me despite being a mechie.
The problem I have is that it’s not clear to me if I am dealing with a compact or non-compact section as per table You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
I also need to determine this for a flexion analysis in the weak axis. Therfore it is inherently compact.
