On Stability Theory of Thin-walled Rods of Open Profile Taking Account of Shears

摘要

Let us consider a thin-walled, constant-section, rod of open profile with one plane of symmetry which is simultaneously the plane of greatest stiffness;the rod is loaded by longitudinal and transverse loadings in this plane.nUnder such conditions buckling of the first kind /l/ is possible, i.e., when the loading reaches some critical value, a new equilibrium mode accompanied by side deflections and angles of twist will appear in addition to the fundamental equilibrium mode.nIn order to obtain the stability differential equations, let us examine the equilibrium of rod in the strained state.
