steel on steel min. bearing lengths

steel on steel min. bearing lengths

(OP)
Does anyone know where I can find minimum bearing lengths for steel on steel? I looked in the AISC manual, but could not find anything. Thank you in advance.

RE: steel on steel min. bearing lengths

Don't know about AISC, but in the case of a steel joist CSA S-16 requires a minimum of 65mm (2.5") but where bearing area is restricted, this may be reduced, provided that the shoe is adequately proportioned and anchored to the support. (Article 16.5.11.3)

RE: steel on steel min. bearing lengths

Cmbyrd77:
You have to define your bearing problem better than you have. Steel ball bearings actually have a fairly small bearing length and width. Under what situation would we want AISC defining a min. bearing length of steel on steel, and restricting our design options, as long as our design does not exceed the allowable bearing stress, or some other critical design consideration. I suppose that next year they will come out with an all new Design Guide #356, 738 pages, on min. allowable bearing lengths for all possible steel on steel situations. But, within two days, three conditions that they hadn’t thought about will come to light, so then they will be hawking an all new 2nd Ed. before the second printing of the 1st Ed.
