French term or phrase: efforts d'about
I suspect a typo here.

Context: "Cette note de calcul ne vérifie pas l'appui de la poutre métallique sur son support; l'entreprise et le BET devront prendre les dispositions constructives nécessaires pour permettre une bonne transmission des EFFORTS D'ABOUT, de la poutre à son support (vérifier la concentration de contraintes de compression sur la poutre et son support)."
Clayton Causey
end(-block) forces
Explanation:
The constant reference to steel beams is troubling given that much of this document seems to be about concrete ...

In prestressed (or post-tensioned) beams, etc., about is the name given to the "end block", that part of the member with complex forces at play, due both to the fact that anchoring of prestress tendons at the end is all-important, and the stresses particularly high, such that the concrete might burst apart, AND to the fact that the end of the beam etc. is generally where its load rests on supports.

I'm not aware that about is generally used for steel members, but then I don't do a lot of work with steel, so it's entirely possible that it IS the term for the "end" of steel beams. I don't think "end block" would be applicable here because the forces at play are less complex (I think) given that steel is a single material, unlike concrete beams which contain passive and active reinforcing steel.

Strictly speaking, also, efforts is "forces AND moments", but there's probably no need to be so specific and complicate matters unnecessarily.

Appears about is said of the end of all beam-type elements, irrespective of material or materials.

Could be a pad of some material inbetween beam and support: bedplate/soleplate.

agree  Bashiqa: We had baseplate earlier on. Often the 'pad' is some sort of resin to bed the beam onto.

forces about a given point


Explanation:
It appears to be a mix of the two languages, but given they talk about compression etc. this is a possibility.
