The resistance of aluminum alloys to the actions that are characteristic of operation in the load-bearing structures of bridge constructions, namely, fatigue, static, impact loads, and crack propagation, is studied. It is shown that, in bridge building, medium-strength aluminum alloys of the Al-Mg, Al-Mg-Si, and Al-Zn-Mg systems should be used. The specific features of deformation and fracture of aluminum alloys that affect their ductility, fracture energy, fracture toughness, and fatigue life are revealed.
