Slenderness of a tension member

Slenderness of a tension member

Slenderness of a tension member

(OP)
Dear Colleagues,

The AISC code limits the slenderness for both compression and tension members.
Which value we should consider for buckling factor K of lambda=k*l/r for calculate the slenderness ratio of a tension member, taking account that the values of K was stablished for members under compression load under some combinations of external supports? Should we use 0.5 teorical(0.65 Recommended for fixed-fixed ends) for all cases?

Thanks,

Marx Pio

RE: Slenderness of a tension member

The effective length factor, K, does not apply to the slenderness ratio recommendation for tension members.  See AISC specification section B7.  In other words, use K=1 for all cases in tension.

RE: Slenderness of a tension member

Yes,

And additionally:  AISC does not mandate the limit on the slenderness ratio, but rather recommends a limit.  They use the word "preferably".

RE: Slenderness of a tension member

Agree in determining the slenderness on actual length for members in tension, or take K=1.

... and the preferably is preferable, will the member some day enter in -even marginal- compression?. I think they degraded it to preferably because otherwise the cable or tensors practice would become too much in evidence.
