Inelastic lateral stability under moment gradient
Lateral stability of mild steel I beams simply supported on single span and loaded beyond yield with concentrated load at mid span is examined; analysis uses theorem of stationary potential energy and tangent modulus; it compares certain approximations regarding buckled shape, variation of lateral, warping and torsional rigidities with moment beyond yield and stress-strain properties of steel and shows that assumed linear relations agree well with set of experimental results from tests on small scale steel models; approximate method for calculating critical moment-length relations for standard I and WF beams under similar loading conditions is suggested.
