Allowable defects on beams

Allowable defects on beams

Allowable defects on beams

(OP)
Hi, some of the beams we adquired for the construction of a skid, came withs "details" so its there a rule or a specification, that describe the allowable defects on beams?. One of the beams came with a scratch of 0.6 mms deep, on the web section. the question its if we can use that beam or just we have to discard it.

               Thanks.

RE: Allowable defects on beams

AISC has specs on tolerences.  More importantly, a deep scratch in high tension zone will lead to a stress crack under load.  I recommend grainding out and patching the deep scratch.  

RE: Allowable defects on beams

and then (if you can) orient the beam so that the repair is on the compression side of the bending stress field; or at least as far form the peak tension stress..
