depression. Chronic fatigue is one of the most diseases that is linked to too much work and depression ( Barroso et al., 2016; Schulz, Bloom, & Kinnunen, 2017 ). Fatigue is described as a subjective feeling, experience, sense or awareness that is akin to
The paper presents a case study that summarizes the monitoring results of a steel bridge strengthening project where a damaged structural element was temporary strengthened with fiber reinforced plastic sheet. The evolution of damage and the effects of strengthening were monitored with a computerized 24-channel displacement measuring system during normal traffic operation. The results of the monitoring project confirmed the efficiency of the proposed strengthening solution by comparing displacement results prior and after the strengthening intervention, and highlighted the need for applying a system that is capable to follow fatigue damage evolution.

The fatigue-life (traction-traction only) is experimentally studied mainly for pseudoelastic NiTi wire of 2.46 mm of diameter
for eventual application in damping of structures under wind or rain. Thermal effects are highly relevant in determining the
fatigue-life. The results shows that the fracture level overcomes 130000 cycles when the moving air is used for cooling. When
the number of working cycles overcomes 30000, the frictional energy decreases 40% vs. N roughly with an exponential behavior.

The paper describes the present methodology for assessment of safety of bridges and the remaining life of steel railway bridges. The majority of railway existing bridges are riveted, and this field has been researched in former studies, but there are also many welded bridges. Many bridges are still in operation after damages, several phases of repair and strengthening. The replacement of old bridges raises some technical and financial problems. This is the main reason why new method for assessment, based on fracture mechanics principles is researched.
Assessment of seismic safety of nuclear power plants requires convolution of plant fragilities with seismic hazard curves. Plant level fragility versus peak ground acceleration is obtained by combining component fragilities according to the Boolean-expression of the sequence leading to core damage. An improvement of the fragility modeling can be achieved via description of the fragility as a function of cumulative absolute velocity of ground motion instead of peak ground acceleration. In the paper the physical meaning and dependence on strong motion parameters is also discussed. The reason why the cumulative absolute velocity is an appropriate damage indicator is analyzed.
