Unlike the tensile effort, which tends to straighten the parts, the compression effort tends to accentuate the effect of the initial curvature. The lateral displacements produced make up the flexural buckling process. The buckling of the part tends to reduce its load capacity.Source: Neto, J. G. R.

Accessed on: 05/10/2024. Checking the safety of compressed parts varies depending on the slenderness of the part. A column with a circular section and buckling length equal to 320 cm is classified as moderately slender. Knowing that it receives a centered force of 480kN, carry out the necessary calculations and select the alternative that presents the requirements associated with its correct dimensioning. AlternativesAlternative 1:A simple compression generated by the load 480.0 kN. Alternative 2:A simple compression generated by the load 512.0 kN. Alternative 3:A flexion-compression caused by a load of 480.0 kN plus a moment of 5.1 kN.m. Alternative 4:A flexion-compression caused by a load of 480.0 kN plus a moment of 24.0 kN.m. Alternative 5:A flexion-compression caused by a load of 480.0 kN plus a moment of 512.0 kN.m.
