It is shown that service life of welded structures can be extended using safety factors allowed for in design of these structures and based on differences in their actual operating time and assigned life time. The method is suggested to reveal the above safety factors in order to estimate residual life of the structures on the basis of main design parameters affecting it.
Keywords: structure, residual life, service life, operating time, extension, accumulation of fatigue damage, fatigue resistance, durability, calculation
