摘要：

It has been observed in experiments that the localization of plastic buckling patterns has a large influence on the strength deterioration of steel structures under cyclic loading. In this study the theoretical aspects of this cyclic localization phenomenon were investigated, The localization behavior is caused by a plastic bifurcation on the decreasing equilibrium path subsequent to the maximum load point. Thus, we first show a precise numerical method based on the finite element method for analysis of the plastic bifurcation. Then, using this method, we examine the localization behavior of cylindrical shells and plates under cyclic loading, Specifically, we investigate the effect of structural parameters and that of constitutive models on the strength deterioration.
