【Abstract】 A new method for calculating crane structure reliability based on Monte Carlo and finite element method has been put forward, which has been verified by example and can be served as the theoretical base for improvement of design. The method makes full use of the secondary developing and outputs’ ability of existing finite element software and needs little self programming, and the programable peculiarity of regularity is helpful to extend engineering application in practice.更多还原
