- An advanced finite element model (FEM) is presented with fiber beam-column element of OpenSees in this study. Using this FEM, non-linear static push-down analysis of a steel frame structure was carried out by the alternate load path method, with two different cases that two different columns are removed respectively. Comparison analysis indicate that catenary action can be development in the case of middle column removal only, which is not developed after side column is removed. The reason for development of catenary action is that obvious axial tension force should be created in beams within damaged bay.
