Abstract
in which Ps is the allowable short-column load; Fco is the column yield stress; L' = L/\/c, where c is the fixity coefficient; p is the radius of gyration; and K is a constant of such a value that the short-column and Euler curves of allowable stress versus V / p are tangent at the critical value of V'/p. It is not easy to find from Eq. (1) the proper size tube for a given design load because both A and p are unknown. One way to overcome this difficulty is to construct grid-type nomograms similar to those given by Niles and Newell.* A second method is to construct curves of allowable column load versus L for both the short-column and Euler range, f Unfortunately, Niles and Newell exhibit only one such gridtype nomogram and Bulletin ANC-5 gives curves of allowable column load versus L for X-4130 steel only. Hence, designers might find use for a simpler formula for Ps than that given in Eq. (1).
