heal.abstract	An analytical model is described that includes two types of imperfections: (1) An initial out-of-straightness of the column and (2) an initial eccentricity of the applied axial loading and also the effect of end restraints. The analysis is based on the plastic-hinge concept and takes into consideration the theory of plastic flow in the vicinity of plastic hinges. The effect of end connections is modeled by a combination of elastic rotational springs and connection segments of various flexural strength with the fully plastic moment modified due to axial load. A closed-form solution is obtained using any type of cross-sectional shape by employing a piecewise linear approximation to the analytical expression of the interaction curve. Results are presented that illustrate the imperfection sensitivity of restrained columns under cyclic inelastic loading.	en
