GB 50017/GB 8408

The GB 50017 is a chinese standard for the design of steel structures. The implementation of the code includes the following features:

  • Static strength assessment of base material and welds against material/weld strength
  • Fatigue strength assessment of base material and welds using predefined SN-curves:
    • Assessment against cutoff (1e8 load cycles)
    • Variable amplitude fatigue

The strength assessment of welds uses the nominal stress concept.

Typical applications of the GB 50017 in combination with GB 8408 are the assessments of large-scale amusement devices.
