Abstract: Cold-formed steel members, which experience complicated prestrain histories, are frequently applied inThis paper aims to predict cyclic plasticity of structural steels with tensile and compressive prestrainMonotonic and cyclic tests on hourglass specimens with tensile and compressive prestrain are conductedsteels, and the second requires both the monotonic tensile test data from the virgin steel and the prestrainThe first approach slightly overestimates the compressive stress for specimens with tensile prestrain
