In the authors' previous papers, effective methods to investigate elasto-plastic behavior of the steel structures subjected to repeated and variable loads, which are called as "critical response method" and "residual stress, residual deformation method", were proposed. In this paper, critical response method is modified to be able to consider the influence of the loading history, and its formulation for the frame structure is presented. It is shown that it is only necessary for the modification to update the domain of the repeated variable load along the loading path. In order to verify the validity of the new method, elasto-plastic analyses of the rectangular section beam-column subjected to repeated bending under constant axial force are carried out, and the results of both the constant and the incremental amplitude of bending are compared with those of the step-by-step method.
