Analysis on the Effect of Shear Deformation on Buckling of Compression Bar
Based on the differential relationship between shear strain,axial strain and bending deflection,the bending differential equation of the compressed bar is established,and the buckling load formula of the compressed bar under elastic instability is derived.The calculation results show that the effect of shear deformation on the buck-ling load of the solid compressed bar with uniform cross-section is negligible,but the effect on the latticed compres-sion bar should be considered.At the same time,it is pointed out that it is not proper to say that the deep beam has the same stability problem as the primary beam under the axial force in the relevant literature.
