Title:Inelastic buckling of columns with elastically restrianed ends
Author(s):Collins, William H.; Sidebottom, Omar M.
Abstract:Two methods were presented for constructing curves showing the relationship between average stress and deflection at the central section for columns with elastically restrained ends. Both methods used constant depth of yielding interaction curves, but differed in the assumptions pertaining to the shape of the deflected column. One method assumed that the deflected shape was that of a sine curve. A more exact method divided the column length into several equal segments over which the curvature was assumed to be constant. For the latter method, a digital computer solution was presented. The experimental portion of the investigation involved the testing of twenty 2024-T4 aluminum alloy columns. Two slenderness ratios, 75 and 50, were considered, and axial loads were applied at eccentricities ranging from 5 to 50 per cent of the cross sectional height. Four of the columns were tested with a concentrated lateral load at the central section in addition to the axial load.
