Ductile crack initiation and brittle fracture at steel connections are affected by multiaxial states of stress and strain concentration which occur at discontinuities in shape. Therefore, it is important to find out stress-strain states at steel connections. In this study, tensile test of notched steel plates was performed so that the stress-strain states at steel connection models was measured experimentally, which were compared with analytical solutions by means of a finite element method. It was found that the finite element analysis assuming 3D-solid or plane strain elements is applicable to determining the stress-strain state at steel connections. Furthermore, a criterion for ductile crack initiation in notched steel plates was established.
