Abstract

Abstract

Regarding the crane load as a stochastic process,an analybic method of steel crane beams in service is proposed based on Miner cumulative fatigue-damage.It is used to assess the fatigue reliability varing with time of a steel crane beam in service.The result shows that the fatigue reliability of the steel crane beam in service decreases with the increasing of the time,which can predict the residual fatingue life of the steel crane beam.
- steel crane beam,
- fatigue reliability,
- cumulative fatigue-damage,
- residual life
