Resumo: This paper presents experimental results about the fatigue damage accumulation behaviour of a structural component made of P355NL1 steel. The structural component is a rectangular double notched plate. Two and multiple alternated constant amplitude block sequences were applied for various combinations of remote stress ranges. Three stress ratios were investigated, namely R=0, R=0.15 and R=0.3. Variable amplitude blocks were also investigated according predefined stress spectra. Constant amplitude data was also generated which is applied for damage calculation purposes. In general, the block loading demonstrates that fatigue damage evolves nonlinearly with the number of loading cycles, function of the load sequence, stress level and stress ratios. Generally, the application of variable amplitude loading suggests an important stress ratio effect on fatigue damage accumulation. In particular, a clear load sequence effect is verified for the two block loading, with null stress ratio. For the other (higher) stress ratios, the load sequence effects are almost negligible; however the damage evolution still is non-linear.
