Abstract

Based on the theory of structural reliability, the whole use process of a steel crane beam was considered as a random process.The effect and resistance of the steel crane beam were considered as random variables, and the fatigue dynamic reliability calculation model for the limit stress was studied.The fatigue reliability factors of the steel crane girder were analyzed by using the fatigue dynamic reliability calculation model.Based on the study, the suggestions for fatigue design, operation and maintenance of steel crane beams were put forward.

Key words
