Abstract	The strength of a hybrid girder with a high manganese non-magnetic (Hi-Mn) steel / carbon (SM490; SM) steel (Hybrid girder) was investigated based on the results of the elastic-plastic large deformation analysis. The yield stress and Young’s modulus of Hi-Mn steel were 16% larger and 20% smaller compared with those of SM steel. When the upper half was assembled with Hi-Mn steel and the lower half of the cross section of the Hybrid girder was assembled with SM steel, the yielding moment was 2% and 18% larger than those of the girder with only Hi-Mn steel and the girder with only SM steel. The bending stiffness was 8% larger and 11% smaller than those of Hi-Mn and SM girders. The out-of-plane deformation of the web was larger than those of Hi-Mn and SM girders. By moving the position of the horizontal stiffener of the Hybrid girder 10% lower, the out-of-plane deformation of the web was controlled to smaller than those of Hi-Mn and SM girders.
