| Abstract: | Normative background for the design of crane structures. For the design of crane structures the CEN Technical Specification CEN/TS 13001‐3‐1: 2005 has been prepared in CEN/TC 147. This Technical Specification refers to EN 1990 – Eurocode: “Basis of Structural Design” and to EN 1993‐1‐1: Eurocode 3: “Design of steel structures”, Part 1‐1: “General rules and rules for buildings”, however there are significant deviations from the Eurocode‐rules. Examples for such deviations are the rules for the choice of material to avoid brittle fracture and the detail classes for the fatigue strengths of various details. Also CEN/TC 13001‐3‐1 does not yet contain design rules for plate buckling. This contribution shows examples for such deviations which possibly are based on different approaches to the experimental background of rules. A standardized approach is given in EN 1990 that specifies how to determine characteristic values of resistances from tests and recommended values for partial factors for the Eurocodes. For plate buckling the design methods given in EN 1993‐1‐5 and the reliability background of these rules are explained. |
