  1. Figure 01 - Flanged Guide

    Horizontal Craneway Loads from Skewing of Bridge Cranes

    For crane runways with large spans, the horizontal load from skewing is often relevant for the design. This article describes the origin of these forces and the correct input in CRANEWAY. The practical implementation and the theoretical background are discussed.

  2. Figure 01 - Loading of Lower Flange by Wheel Loads

    Design for the Lower Flange of Suspension Cranes According to DIN EN 1993-6

    For suspension cranes, the bottom chord of the runway girder is subjected to local flange bending due to the wheel loads in addition to the main load bearing capacity. The bottom chord behaves like a slab due to these local bending stresses and has a biaxial stress condition [1].
  3. Figure 01 - Web Welds as Double Fillet Weld

    Design of Web Fillet Welds of Crane Girders According to EN 1993-6

    The article series about the design of crane girder welds is concluded by this article describing the design of web fillet welds, following the previous articles about the design of rail welds of crane girders at ultimate limit state and fatigue limit state. Both the ultimate limit state and the fatigue limit state are considered.

  4. Figure 01 - Weld Stresses in Fatigue Design

    Fatigue Limit State Design of Rail Welds of Crane Girders According to EN 1993-6

    Based on the technical article about the ultimate limit state design of rail welds, the following explanation refers to the process of fatigue design of rail welds. In particular, this article explains in detail the effects of considering the eccentric wheel load of 1/4 of the rail head width.

  5. Consideration of Eccentric Wheel Load Application for Weld Design at ULS

    Consideration of Eccentric Wheel Load Application for Weld Design at ULS

    The eccentric wheel load application of 1/4 of the rail head width has to be considered only for the fatigue design from damage class S3 according to DIN EN 1993‑6. An additional input option in detail settings allows you to consider this eccentricity for the fatigue design at the ultimate limit state as well. By selecting this option, the design with the eccentric load applied is always considered without regard to the damage class.

  6. Consideration of Eccentric Wheel Loading in Fatigue Design

    Consideration of Eccentric Wheel Loading in Fatigue Design

    In CRANEWAY, the eccentric wheel loading of 1/4 of the rail head width is used for the fatigue design of welds as well as for craneway girder design according to the National Annex of Germany and as from the damage class of S3.

  7. Figure 01 - Arrangement Options

    Ultimate Limit State Design of Rail Welds of Crane Girders According to EN 1993-6

    If crane runway girders are designed with flat steel rails, the welding of these rails is always a detail for the design. As a rail fixing, you can generally select between continuous and intermittent fillet weld. The following article provides an overview of the design processes and their specific features, especially when using the EN 1993‑6.

  8. Reducing Dynamic Coefficient Using DIN EN 1993-6

    Reducing Dynamic Coefficient Using DIN EN 1993-6

    The NCI to DIN EN 1993‑6, part 2.3.1 allows reductions of dynamic coefficients for the values ≧ 1.1. Therefore, you can use these reduced support loads for the design of support and hanger structures. In CRANEWAY, if you select the National Annex ‘DIN’ and the dynamic coefficients ≧ 1.1, the reduction is considered automatically.

  9. Support Forces

    Support Forces

    In CRANEWAY 8, the support forces are displayed in the result window 2.3 ‘Support Forces’. There are three display options available.

  10. Consider Rail Section

    Consider Rail Section

    In CRANEWAY, the action of a rail as ‘statically effective’ or ‘statically ineffective’ is defined under ‘Rail‑Flange Connection’ in the Details dialog box. This setting controls the calculation of the load introduction length according to EN 1993‑6, Tab. 5.1.
