Abstract (2. Language): 
The growth of a diagonal fatigue crack in an I-shaped transversely stiffened steel plate girder loaded under predominantly shear may degrade the shear strength of an individual web panel. Analytical expressions were derived for the residual shear force capacity of a cracked web panel. Several limit states were considered including shear yielding, web buckling, brittle fracture, and impending ductile failure. The expressions were validated with finite element analyses and employed to investigate the governing limit states and associated strengths of various web panel geometries. Web buckling was found to be the predominant governing limit state for realistically sized girders. The formulated expressions may be employed in the design and analysis of girders considering prescribed diagonal fatigue crack configurations.
