  1. Model, Dimensions, and Loading

    Comparing the Stability Analysis of a Column Containing Internal Forces from Load Combinations with an Enveloping Result Combination

    This example will show what you should consider when you perform column design for bending and compression with regard to the internal forces from load combinations and result combinations.

  2. 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.

  3. Internal Force My and Influence Line for My for x = 1.25 m

    Basics to Determine and Evaluate Influence Lines

    Influence lines have become less important nowadays due to the fast computer systems. However, it might be an advantage to use influence lines in the phase of preliminary design, but also in the actual creation of the structural designs. With the RF-INFLUENCE add-on module, it is possible to generate and evaluate influence lines and influence surfaces easily due to a fixed internal force. This technical article describes with a simple example the basics to determine and evaluate influence lines.
  4. Explanation of Support Nonlinearities on Example | 2.1 Rotation

    In practice, an engineer often faces the task of representing the support conditions as close to reality as possible in order to be able to analyze deformations and internal forces of the structure subjected to their influence and to enable as much cost‑efficient construction as possible. RFEM and RSTAB offer numerous options for defining nonlinear nodal supports. This second part describes the options for creating a nonlinear support for a restraint and provides a simple example. For better understanding, the result is always compared to a linearly defined support.

  7. Revit Interface: Export

    BIM is often used when it comes to data management in civil engineering. The individual disciplines of architecture, structural design, construction, and structural monitoring are coming closer together. Building Information Modeling makes this possible.

    Dlubal Software provides a wide range of formats for data exchange. The following article explains the details of the interface with Autodesk Revit and, particularly the export settings.

  8. Influence of Connection Stiffnesses on Design of Members and Connections

    Building in existing structures has always been an area of expertise for engineers. Additional loads often have to be added to the existing buildings. In this case, steel girders with end plates and dowel connections are frequently used.

  9. Using Network License via VPN

    The network licenses of Dlubal Software provide a very convenient solution for an engineering office as well as for a user who is often on the move. It can be helpful if you are on a consulting meeting with the building owner and want to directly apply the current changes and show the solution immediately. You only need the Internet and VPN connection in your office and you can access all your purchased licenses.

  10. Optimizing Graphic Printout for Page Size

    For a printout of structural analysis in the usual DIN A4 page format, the default settings of graphic quality of 1000 x 1000 pixels are completely sufficient. However, if the printout should be on the larger page format, you can increase the print quality to the maximum of 5000 x 5000 pixels in the options of Graphic Printout, or specify a user‑defined value.
