Aluminium alloy is characterized by the high strain-hardening rate relative to Young's modulus and round stress-strain relationship above elastic limit. The reduction of strength (softening) in heat affected zone of welded aluminium structures is also one typical characteristic of aluminium alloy. In addition, the shaped stiffened plates with a taper cross-section in plate are widely used in aluminium ship structures. In this paper, the influences of the strain-hardening rate, stress-strain relationship, welding residual stress, reduced strength in heat affected zone and taper cross-section on the buckling/plastic collapse behaviour of aluminium stiffened plates are investigated by using FEM analyses. The simplified method to estimate the ultimate strength of aluminium stiffened plates is developed considering the observed behaviours.
