heal.abstract An analytical study is made of the hysteretic behaviour of a simply supported prismatic steel strut subjected to cyclic loading. The analysis includes the effect of two types of imperfection, namely an initial out-of-straightness of the strut and an initial eccentricity of the applied axial loading. Basic equations are derived in a closed form through an elastic-perfectly plastic type of analysis in conformity with one-dimensional idealization of the strut. The analysis is based on the plastic hinge concept and takes into consideration the plastic flow theory in the vicinity of plastic hinges. The exact interaction curve of any type of cross-sectional shape is adequately approximated by a piecewise linear interpolation of the fully plastic states in pure bending and in pure tension and compression. Results are presented which illustrate the imperfection sensitivity of struts under cyclic inelastic loading. © 1987. en
