Comparative Analysis on the Allowable Stress and Limit State Methods of Crane Structure Design Standards at Home and Abroad

Abstract:

This paper adopts the allowable stress and limit state methods of Chinese and European crane structure design standards(GB3811-2008 and FEM-1998 ), and illustrates correspondingly in detail the computing means on the overall checking of strength, static and dynamics stiffness, buckling of bar and plate, and fatigue. Taking a real crane as an example, according to the above three specifications, it designs the crane’s metal structure again, checks all aspects and guarantees the strength, buckling and fatigue indexes all reach 90 percent of the permissions, then comparative analyzes the new design parameters and checking indicators, combining failure probability obtained by PDS. It provides helpful and reference value for understanding the transition from the allowable stress to limit state method in design standards and the differences of theirs’ at home and abroad.
