pinned connection bearing stress
pinned connection bearing stress
(OP)
I know this has been somewhat addressed but i often see it addressed as it relates to a bolted connection.
I want to confirm that allowable bearing stress for a pinned connection can be treated in a similar fashion as a bolted connection where allowable bearing stress equals a factor of 1.2 to 1.5 times the tensile yield.
Actual load tests confirm that we see more than 2 times this allowable bearing load before hole deformation which backs this up, however i would just like the theoretical argument to add to the test results.
thank you

RE: pinned connection bearing stress
just to confirm, i can then assume that ALLOWABLE bearing stress with a pin load (not bolt or rivet) lies somewhere in the range of 1.2 to 1.5 times the tensile yield.
This is in fact what i believe to be true, but i just want confirmation on the theoretical. I also believe that the ALLOWABLE bearing load incorporates a safety factor of about 2 - do you also agree with that?
Test data we have is in agreement with these assumptions but a source indicated to me that the above relationship may only apply to a bolted connection where friction plays a role.

The safety factor varies with application and it is meaningless to speculate on a "typical" value.

RE: pinned connection bearing stress
does anyone have a link to material property specs that would actually list the ultimate bearing strength and the yield bearing strength for grade 50 A653 steel?
I've been searching and i find that these values are very seldomly listed - probably due to e/D and t/D variability. I have found it for some steel alloys and some aluminum but I can't find it for Grade50 A653 steel.
The values I have found for other materials seem to show that the yield bearing is about 1.75 times the tensile yield.
thanks
I think that due to the fact that i have a pinned joint with no benefit of wall stiffening from a bolted connection i want to work from specified bearing yield to obtain WLL.
