The authors have proposed a phenomenological fiber model to simulate local buckling behavior of steel structural components in building frames. This phenomenological model captures development of the plastic strain localization of steel columns subjected to high axial load. This study presents the accuracy of the phenomenological fiber models applied to truss members. As a result, the phenomenological fiber model simulates the force-deformation relationship of the truss members including local buckling. This phenomenological fiber model is used for numerical simulation of a braced steel frame with incremental dynamic analysis to investigate the effect of local buckling on the ultimate seismic performance.
