Therefore, a stress-strengthinterferencemodel for the reliability calculation of rock mass under two-end truncated probability distribution was proposed with the help of distribution theories.
Since the main failure reason of the steel rope is the fatigue of the metal, the fatigue reliability design of the crane steel rope can be executed by means of stress-strengthinterferencemodel.
Then, the complex integral calculation problem in the reliability model of stress and strengthinterference was simplified by using the Monte Carlo Simulation Method.
