Standability of rods from hardening materials and normative calculations
Abstract: On the base of rigorous analysis of equilibrium paths of compressed elastic-plastic bars under central and eccentric compression the influence of hardening on limit loads is studied for modern materials whose stress-strain diagram has no explicit yielding plateau. It is shown that a certain “threshold” value of the hardening parameter exists below which the limit loads do not practically depend upon hardening. In this range the existing design codes provide a rather good prediction of limit loads. However for modern materials with hardening, which exceeds the threshold value, the existing design codes are not able to predict limit loads in the whole range of slenderness ratio.
Keywords: metal construction, standability, stress and stress-bending elements, strain diagrams, hardening, codes.
