Review of fatigue design rules for welded structures

摘要

Current fatigue design regulations have been revised from the point of view of the latest: research and changes in the needs of the industry. The data obtained indicate that it is necessary to make many amendments in the regulations and broaden their limits. The issues considered include classification of butt and cruciform joints and allow for die welds made by the methods other than arc welding, scale effect, 《hot spot》 stress estimation method, as well as methods for calculation of complex combined loading and cumulative damage.
